Presentation
The Schneider Electric range of instrument transformers is designed for voltages from 0.72 kV to 36 kV and rated currents from 5 A to 4000 A. In order to meet requirements for increasingly high short circuit current values in installations, current transformers notably have a short-time thermal current of 60 kA x 1 second. All Schneider Electric instrument transformers are in conformity with IEC standards. b Current transformers can specically meet requirements for: v accuracy classes TPS - TPX - TPY TPZ dened by standards IEC 60044-6 relative to recommendations concerning transformer behaviour during transient short circuit conditions v standard IEC 60079-7 / EN 50.019 concerning enhanced safety electrical equipment for explosive gaseous atmospheres b Through their standardized conguration, their high electrical performance levels, their reduced weight and space requirement, these devices are particularly well suited for use with: v LSC2B type cubicles (metal clad) v LSC2A type cubicles (compartmented) v large motor terminals v explosive gaseous atmosphere environments (Eex).
Conformity with standards

All Schneider Electric instrument transformers are in conformity with IEC standards, sections 2099 - 2134, and recommendations 60044-1/IEC 60044-2. Transformers in conformity with specic country standards can also be supplied (IEEE C57.13, NBR6855, NBR6856).
Main features
The working parts (windings and magnetic cores) are entirely enclosed in an epoxy resin bloc casting whose twofold function is to: b guarantee both internal and external electrical insulation of the device b provide enhanced mechanical strength. Product quality over time is guarantee not only by thirty years experience in manufacturing resin insulated instrument transformers, but also by the use of silica lled epoxy resin which gives: b high dielectric strength, even at high temperatures (18 kV/mm at 180C for 20.000 hours) b insulation class B according to IEC 60044-1 b high ageing resistance, both thermal, resulting from increase in temperature of structures according to IEC 216 (more than 20 years at 120C), and surface through salt mist withstand b lack of emissions of any harmful substances in the case of f re, in conformity with IEC standards IEC 60020-37, IEC 60020-22 and ASTM D 3286 b outstanding behaviour in tropical climates b high mechanical strength, even at high service: epoxy resin glass transition temperature 105C. Rigorous production procedures enable: b no blisters or blowholes in the resin thanks to vacuum casting b a partial discharge value with a low time constant, also due to the quality of insulating materials used b high resistance and very good electrical conductivity at the primary and secondary terminals, even at temperatures reached during short circuit, due to mechanical connections b the consistency of production parameters over time, through a computer controlled system which manages and monitors the whole production line.

Applications and types
Protection or metering devices have to receive data on electrical values (current or voltage) from the equipment to be protected. For technical, economic and safety reasons, this data cannot be obtained directly on the equipments MV power supply; we have to use intermediary sensors: b Current transformers b Voltage transformers. These devices carry out the functions of: b Reducing the size of value to be measured b Providing galvanic separation b Supplying the power needed to process the data, or even for the protection device to work.
Metering transformer applications

In MV electrical distribution, the high current and voltage values mean that they cannot be used directly by metering or protection units. Instrument transformers are necessary to provide values that can be used by these devices which can be: b analogue devices, directly using the supplied signal b digital processing units with a microprocessor, after analogue/digital conversion of the input signal (e.g.: Sepam or Power Logic System).
DE58030EN
Example of a metering transformer application in a protection system
Types
Instrument transformers are of the following types: Current transformers Connected on the MV network primary circuit, they supply a reduced current value to the secondary circuit, proportional to the network current on which they are installed. There are two types: b CT: current transformer b LPCT (Low Power Current Transformer): electronic current transformers. Voltage transformers Connected to the MV network primary, they supply the secondary circuit with a reduced voltage value, proportional to the network voltage on which they are installed.

Technical description
Current transformers (CT) meet standard IEC 60044-1. Their function is to supply the secondary circuit with a current that is proportional to that of the MV circuit on which they are installed. The primary is series-mounted on the MV network and subject to the same over-currents as the latter and withstands the MV voltage. The secondary generally has one of its terminals connected to earth. The secondary must never be in an open circuit (short circuit).
DE58058
Current transformers
Current transformers have two basic functions: b adapting the MV current value at the primary to the characteristics of the metering or protection devices by supplying a secondary current with a reduced, but proportional current value b isolating power circuits from the metering and/or protection circuit.
Composition and types

A current transformer comprises a primary circuit and a secondary circuit connected via a magnetic core and an insulating coating system in epoxy-silica, in the case of Schneider Electric transformers. The device is of the following type: b wound: when the primary and the secondary have a coil wound on the magnetic circuit b slip-over: primary made up of a conductor that is not insulated from the installation b core: primary made up of an insulated cable.
Characteristics
These are dened in standard IEC 60044-1. Insulation Characterized by the rated voltage: b of the insulation, which is that of the installation (e.g.: 24 kV) b of the power frequency withstand 1 min (e.g.: 50 kV) b of the impulse withstand (e.g.: 125 kV). Rated frequency 50 or 60 Hz. Rated primary current (Ipn) Rms value of the maximum continuous primary current. Usual values are 25, 50, 75, 100, 200, 400, 600 A. Rated secondary current (Isn) This is equal to 1 A or 5 A. Rated transformation ratio Kn = I rated primary / I rated secondary (e.g.: 100 A / 5 A) Short-time thermal current Ith - 1 second This characterizes the thermal withstand under short circuit conditions for 1 second. It is expressed in kA or in a multiple of the rated primary current (e.g.: 80 x Ipn) for 1 second. The value for a duration that is different to 1 second is given by: Ith = Ith/2 For example 16 kA - 1 s is equivalent for 2 s to Ith = 16 x 2 = 22.6 kA.

The choice of CT is decisive in order for the overall metering or protection system to work properly.
CT operation
Importance of CT selection The operating accuracy of metering or protection devices depends directly on the CT accuracy. Operating principle A CT often has a load that is quite resistive (Rc + its wiring), as shown in the schematic diagram below.
DE58031EN
Schematic diagram for a current transformer I1: primary current. I2 = Kn I1: secondary current for a perfect CT. Is: secondary current actually owing through the circuit. Im: magnetizing current. E: induced electromotive force. Vo: output voltage. Lm: magnetization inductance (saturable) equivalent to the CT. Rct: resistance at the CT secondary. Rwir: resistance of the connection wiring. Rc: load resistance.
Current I2 is a perfect image of the primary current I1 in the transformation ratio. However, the actual output current (Is) is subject to an error due to the magnetization current (Im). I 2 = I s + I m if the CT was perfect, we would have Im = 0 and Is = I2. A CT has a unique magnetization curve (for a given temperature and frequency). With the transformation ratio, this characterizes its operation. This magnetization curve (voltage Vo, magnetizing current function Im) can be divided into 3 zones: 1 - non-saturated zone: Im is low and the voltage Vo (and therefore Is) increases virtually proportionately to the primary current. 2 - intermediary zone: there is no real break in the curve and it is difcult to situate a precise point corresponding to the saturation voltage. 3 - saturated zone: the curve becomes virtually horizontal; the error in transformation ratio is high, the secondary current is distorted by saturation.

Metering CT or protection CT
We have to choose a CT with characteristics that are suited to its application. Metering CT This requires good accuracy (linearity zone) in an area close to the normal service current; it must also protect metering devices from high currents by saturating earlier. Protection CT This requires good accuracy at high currents and will have a higher precision limit (linearity zone) for protection relays to detect the protection thresholds that they are meant to be monitoring.

Feasability of a CT
We can dene the over-current coefcient of the CT:
Ksi =
I th 1s I pn
The lower Ksi, the easier the CT is to produce with a given volume, compatible with being integrated in a MV cubicle. A high Ksi leads to over-dimensioning of the CT and makes it difcult to produce. Ksi order of magnitude
Ksi < 100 100 < Ksi < 300 300 < Ksi < 400 400 < Ksi < 500 Ksi > 500
CT production
Standard Sometimes difcult for certain secondary characteristics Difcult Limited to certain secondary characteristics Sometimes impossible
Safety
The CT secondary is used at low impedance (virtually in short circuit). The secondary circuit should never be left open, since this would mean connecting across an innite impedance. Under these conditions, hazardous voltages for personnel and equipment may exist across the terminals.
Terminal marking
CT connection is made to the terminals identied according to the IEC: b P1 and P2 on the MV side b S1 and S2 on the corresponding secondary. In the case of a double output, the rst output is identied by 1S1 and 1S2, the second by 2S1 and 2S2.

CTs for metering must have the right accuracy for the rated current. They are characterized by their accuracy class (generally 0.5 or 1) as well as a safety factor Fs. Example: 400/5 A, 15 VA, cl 0.5, FS 10
Primary current Secondary current Accuracy power (see explanation in the example) Safety factor Accuracy class
CT for metering
Accuracy class A metering CT is designed to send as accurate an image as possible of currents below 120% of the rated primary. IEC standard 60044-1 determines the maximum error in the accuracy class for the phase and for the module according to the indicated operating range (see error limits table opposite). These accuracy values must be guaranteed by the manufacturer for a secondary load of between 25 and 100% of the accuracy power. The choice of accuracy class is related to the application (table opposite). The usual accuracy class is 0.5. there are metering classes of 0.2S and 0.5S specically for metering applications. Safety factor: FS In order to protect the metering device connected to the CT from high currents on the MV side, instrument transformers must have early saturation characteristics. The limit primary current (Ipl) is dened for which the current error in the secondary is equal to 10%. The standard then denes the Safety Factor FS.

The table or error limits given for class 0.5 for a primary current: b between 100% and 120% of the rated current (here 200 A to 240 A), a current error y 0.5% and the phase shift error of y 30 min. b at 20% (here 40 A) the error imposed by the standard is less than or equal to 0.75% b between 20% and 100% of the rated current the standard does not give the metering point and the maximum error is between 0.5 and 0.75%, with a normally permitted linear variation between these two points. b safety factor FS = 10 For a primary current greater than 10 times the rated current, in other words here 2000 A, we will have a metering error > 10% if the load is equal to the accuracy load; for a load less than this we can still be in the linear part of the magnetization curve.

Accuracy class A protection CT is designed to send as reliable an image as possible of the fault current (overload or short circuit). The accuracy and the power are suited to these currents and different from those for metering applications.

For example for class 5P the maximum error is y 5% at the accuracy limit current and y 1% at the rated current. Standardized classes are 5P and 10P. The choice depends on the application. The accuracy class is always followed by the accuracy limit factor. Accuracy class according to application Application

Accuracy limit factor: FLP A protection CT must saturate at sufciently high currents to enable sufcient accuracy in the measurements of fault currents by the protection device whose operating threshold can be very high. We dene the limit primary current (Ipl) for which current errors and phase shift errors in the secondary do not exceed values in the table opposite. The standard then denes the accuracy limit factor FLP.
FLP =
Ip l (standardized values: 5 - 10 - 15 - 20 - 30) Ip n
In practice this corresponds to the linearity limit (saturation curve) of the CT. Example Protection CT: 100/5 A, 7.5 VA, 5P20. b rated primary current 100 A b rated secondary current 5 A b rated transformation ratio 100/5 A b accuracy power 7.5 VA b accuracy class 5P. Under a load corresponding to the accuracy power of 7.5 VA, the error limit table gives an error y 1% and 60 min at Ipn (100 A). b accuracy limit factor 20. At a load corresponding to the accuracy power, the error y 5%.

LPCTs (Low Power Current Transformers) meet IEC standard IEC 60044-8. These are CTs with a direct voltage output which has the advantage of having a very wide range of applications, simplifying selection.
DE58034
LPCT low power current transformers

LPCTs are specic current sensors with a direct voltage output of the Low Power Current Transformers type, in conformity with standard IEC 60044-8. LPCTs provide metering and protection functions. They are dened by: b the rated primary current b the extended primary current b the accuracy limit primary current or the accuracy limit factor. These have a linear response over a large current range and do not start to saturate until beyond the currents to be broken.
Examples of LPCT characteristics according to IEC standard 60044-8

These characteristics are summarized in the curves below. They show the maximum error limits (as an absolute value) on the current and the phase corresponding to the accuracy class for the given examples. They give the same error limits shown for these classes in page 9, but with much wider current ranges, which gives an advantage to this type of sensor. Example for metering class 0.5 b rated primary current Ipn = 100 A b extended primary current Ipe = 1250 A b secondary voltage Vsn = 22.5 mV (for 100 A on the secondary) b class 0.5: v accuracy (see denitions page 13) on: - the primary current module 0.5% (error y 0.5%) - the primary current phase 60 min (error y 30 minutes) over a range of 100 A to 1250 A v accuracy 0.75% and 45 min at 20 A v accuracy 1.5% and 90 min at 5 A. which are two metering points specied by the standard. Example for class 5P protection b primary current Ipn = 100 A b secondary voltage Vsn = 22.5 mV b class 5P: v accuracy (see denitions page 9) on: - the primary current module 5% (error y 5%) - the primary current phase 60 min (error y 60 minutes) on a range of 1.25 kA to 40 kA.
The LPCT and Sepam guarantees a very high coverage range and exibility of usage. Example: protection system with CLP1 or CLP2 and Sepam guaranteeing a usage range of 5 A to 1250 A.

Voltage transformers (VT) meet standards IEC 60044-2. Their function is to supply a voltage proportional to the MV circuit that they are installed on to the secondary. The primary, which is parallel mounted on the MV network between phases of from phase to earth, is subject to the same over-voltages as the latter. The secondary supplies a voltage that is virtually constant, whatever the load. The secondary must never be placed in short circuit.
DE52477
Voltage transformers (VT)

Voltage transformers have two key functions: b adapting the value of MV voltage on the primary to the characteristics of metering or protection devices by supplying a secondary voltage that is proportional and lower b isolating power circuits from the metering and/or protection circuit.
Composition and type

These comprise a primary winding, a magnetic core, one or several secondary windings, with everything encapsulated in an insulating resin. There are two types, according to how they are connected: b phase/phase: primary connected between two phases b phase/earth: primary connected between a phase and the earth.
Characteristics
These are dened by standard IEC 60044-2. Insulation Characterized by the rated voltages: b insulation voltage, which will be that of the installation (e.g.: 24 kV) b power frequency withstand 1 min (e.g.: 50 kV) b impulse withstand (e.g.: 125 kV). Rated frequency 50 or 60 Hz.
Simplied schematic diagram of a voltage transformer IS: secondary current Us: secondary voltage Zc: load impedance.
Rated primary voltage (Upn) According to their design, voltage transformers are connected: b either between phase and earth and in this case Upn = U/3 (e.g.: 20/3) b or between phases and in this case Upn = U. Rated secondary voltage (Usn) This is equal to 100 or 110 V for phase/phase voltage transformers. For single phase, phase/earth transformers, the secondary voltage must be divided by 3 (e.g.: 100/3). Accuracy power Pn Apparent power (VA) that the VT can supply the secondary for the rated secondary voltage for which the accuracy is guaranteed (accuracy load). Standardized values 30, 50, 100 VA (IEC).

Accuracy class Denes the error limits guaranteed relative to the transformation ratio and the phase shift under specied conditions of power and voltage. Voltage error (%) Error that the transformer introduces into the voltage measurement when the transformation ratio is different from the rated value. Phase shift or phase error ( in minutes) Phase difference between primary and secondary voltages, in angle minutes. Rated voltage factor KT This is the factor, a multiple of the rated primary voltage, which determines the maximum voltage which the transformer must meet the specied temperature rise and accuracy recommendations. The maximum operating voltage depends on the network neutral system and the earthing conditions of the primary winding. Table of voltage factors KT Voltage factor

(1) When there is a major difference between the highest voltage for the equipment (Um) and the rated primary voltage, the power frequency must be limited to ve times the rated voltage.
VT operating characteristics
Operation of a VT is more simple than that of a CT because the secondary voltage is virtually independent of the load, due to it being connected through a high impedance (virtually used in an open circuit). Therefore, the secondary must not be short circuited. Under these conditions an excessively high current will damage the transformer.

VT connections
Several metering connection arrangements are possible (g. opposite) b star-connection of 3 transformers: requires 1 isolated MV terminal for each transformer b connecting to 2 transformers, so-called V-connection: requires 2 isolated MV terminals per transformer.

Residual voltage metering

The residual voltage which characterizes the voltage of the neutral point relative to earth, is equal to the vectorial sum of the three phase-earth voltages. The residual voltage is equal to 3 times the zero-sequence voltage V0.
DE52356
Vrsd = 3 V0 = V1 + V2 + V3
Please note, it is impossible to measure a residual voltage with phase/phase VTs.

The appearance of this voltage signies the existence of an earthing fault. It is obtained by measurement or by calculation: b measuring by three voltage transformers whose primary circuits are star-connected and whose secondary circuits are open-delta connected, supplying the residual voltage 1 b calculation by the relay based on three voltage transformers whose primary and secondary circuits are star-connected 2 .

Voltage transformer for metering

Accuracy class These devices are intended to send an image as accurately as possible of the rated primary voltage between 80 and 120% of the latter. The accuracy class determines the permissible error in the phase and in the module in this range for the accuracy load. It is valid for all loads of between 25 and 100% of the rated accuracy power with an inductive power factor of 0.8. The table below gives the usual classes according to application. Application

They must have the right accuracy and power for the fault voltages and therefore different from those used for instrument transformers. In practice, the accuracy class 3P is used for all applications and the error limits for voltage and phase given in the table below. These are guaranteed for all loads of between 25 and 100% of the accuracy power with an inductive power factor of 0.8. Error limits for each accuracy class Accuracy class Voltage error ( %) between 5% Upn 2% Upn and KT and KT

Phase-shift error (minutes) between 5% Upn 2% Upn and KT and KT

3P 3 6P 6 KT: over-voltage coefcient. Upn: rated primary voltage.
Example: Protection voltage transformer 20 000 / 110 , 100 VA, 3P, KT = 1.9 8h 3 3 b rated primary voltage 20000 V/3, rated secondary 110 V/3 b accuracy power 100 VA b accuracy class 3P. The table of limit values shows that for: v a primary voltage of 5% of the rated voltage at KT times the rated voltage, i.e. 20000 x 5% = 1000 V at 20000 x 1.9 = 38000 V v a load of between 25% and 100% of the accuracy power, in other words of between 25 VA and 100 VA with a power factor of 0.8, the metering error will be y 3% in voltage and y 120 min in phase shift.

Connecting a VT
VT with a double (or triple) secondary A VT can have one or two secondaries (gure opposite), and more rarely three secondaries for the appropriate applications (protection and/or metering). Identifying terminals A VT is connected across the terminals identied according to the IEC: b A for phase and N for earth on the MV side b a and n on the corresponding secondary side. In the case of a double output, the rst output is shown by 1a and 1n, the second by 2a and 2n. Single (grounded) pole
