Chokes Basic information
Choke coils:
Choke coils are inductors and hence reactance coils. The energy content of the magnetic eld generated by a coil with current owing through it is signi-
cantly increased through a high-permeability iron core.
Riedel Choke coils are designed as iron core chokes with air gap.
Our range encompasses, apart from extensive specially manufactured products calculated for the concrete application cases, a standard supply range
consisting of:
Single-phase line chokes
RENDr series
Nominal voltage: 230VAC, voltage drop: 4%
Single-phase double line chokes
RDNDr series
Nominal voltage: 400VAC, voltage drop: 2 x 2%
Three-phase lter circuit chokes
RFDr 7 series
Nominal voltage: 3AC 400V, choke factor: 7%
Three-phase line chokes
RNDr series
Nominal voltage: 3AC 400V, voltage drop: 4%
Line chokes
(commutation chokes)
Use of line chokes is necessary for current limitation and for suppressing line reactions and commutating dips.
The current IG limited by the line choke is calculated as follows:
IG =
IN x 100 %

Uk
For connection of converters to the AC grid inductances are always necessary on the grid side for limitation of commutating dips in grid voltage. If the con-
verter is fed via a converter transformer its control inductance assumes the limitation. For direct connection or supply via autotransformer use of a current-
limiting line current choke is absolutely necessary to comply with the criteria specied in DIN VDE 0160 part 2.
Three-phase lter circuit chokes
Three-phase lter circuit chokes are used in reactive current compensation systems. With the capacitors in the reactive current compensation system they
form a series resonant circuit and thereby produce dened grid conditions. Through the choking of reactive current compensation systems resonance with
the grid harmonics is avoided. The inductance of the lter circuit chokes is selected such that the resonance frequency of the series resonant circuit built from
capacitor and lter circuit choke lies below the lowest frequency of the occurring harmonics.
Through increasing operation of converters and inverters harmonics occur in the grid. From operation of 6-pulse bridge circuits the grid is loaded with cur-
rents with the harmonic order
n = 6 x k +/-1for k =1, 2, 3,...
. The amplitudes of the currents get smaller as the harmonic order increases.

General information:
Use of double line chokes is necessary for current limitation and for suppressing line reactions and
commutating dips. By dividing of the inductance to both grid supply lines symmetric connection of the
consumer is achieved. About half of the voltage drop occurs on each coil section. Coil connection in
series and in parallel yields additional application possibilities up to double the nominal current and half
the voltage drop.
Current limitation is carried out preferentially at 25 times the nominal current. For this line chokes with a
short circuit voltage of 4% (2 x 2%) must be used.
The grid choke must be selected according to the nominal current of the consumer.

Chokes RFDr
General information:
Three-phase lter circuit chokes are used in reactive current compensation systems. With the capacitors
in the reactive current compensation system they form a series resonant circuit and thereby produce
dened grid conditions.
Three-phase lter circuit chokes with adapted outputs ensure the specied compensation reactive
power when interconnected with capacitors of the given capacity.
Three-phase lter circuit chokes without adapted outputs are designed according to the capacitors
used and lead to deviating compensation reactive powers.
For frequently selected chokes of 7% the series resonant circuit formed from the lter circuit choke and
the compensating capacitors yields a resonance frequency of 189Hz.
Design:
Open frame upright design, stationary, for device installation and assembly in dry rooms. Connec-
tion up to 12.5kVAr to leakage current-resistant transformer terminals with screw and tab connectors
2.8x0.8mm to 5A, 6.3x0.8mm to 20A. The 2.8x0.8mm tab connector must only be loaded to 5A in ac-
cordance with DIN 46249 and 6.3x0.8mm to 20A. Above 12.5kVAr to 25kVAr universal terminal blocks
with screw connection and at 30kVAr and above pressed cable lugs are used. The terminals are pro-
tected against back of hand and nger contact according to accident prevention regulations (BGV A3).
With temperature switch in middle coil.

Three-phase motor lter for operation on
frequency converters according to VDE
0570 part 2-20, EN 61558-2-20
Motor lter (series RDMF):
The motor lters RDMF from Michael Riedel Transformatorenbau GmbH reduce the voltage increase
speeds to less than 500V/s. The motor lters are supplied standard up to a nominal voltage of 3AC
690 V and a nominal current up to 1200A. In addition the noise emission is signicantly reduced due to
a unique core geometry. The use of RDMF is recommended for motor cable supply lines of up to 250 m
length.
Technical data:
Rated voltages: 33AC 400V to 3AC 690V (higher voltages available on request)
Rated current: up to 1200 A (higher currents available on request)
Frequency: 50Hz to 60Hz (higher frequencies available on request)
Cycle frequencies (PWM): 1.5kHz up to 8.0kHz
Ambient temperature: ta = 40C / F, S1/100% ED
Cooling types: AN
Protection class: IP00 (higher protection classes available on request)
Design: compact, open design for installation in dry rooms
Advantages:
Low noise lter due to new core geometry (veried by noise level measurements on the Aalen Hoch-
schule)
Reduction of overvoltages on the motor insulation (longer motor running times)
Long motor feed lines possible
Lower noise development on motor

Three-phase sine lter for operation on
frequency converters according to VDE
0570 part 2-20, EN 61558-2-20
Sinus lter (series RDSF):
The sine lter series RDSF (output lter for frequency converter) from Michael Riedel Transformatorenbau
GmbH are tailor-made for the technical requirements of modern drives (FC). By using modern frequency
converters in motor control, high harmonic components result with the cycled output voltages. These
harmonic components additionally load the motor insulation, which leads to shorter motor lifetimes.
Through the use of the RDSF sine lters these additional losses are reduced even when using longer
motor feed lines and thus help to prevent premature failures and costly downtimes.
Technical data:
Rated voltages: 3AC 400V to 3AC 690V (higher voltages available on request)
Rated current: up to 1200 A (higher currents available on request)
