Embodiment
Embodiments of the invention detect the rate of change of fast current including the use of the hollow current transformer that PCB is instantiated（dI/
dt）, as non-limiting example, this can be created during connecting with parallel arc fault event in aircraft distribution feeder
Build.In history arc fault detection systems, in the past using resistor-capacitor hardware differentiator come from solid-state power controller
（SSPC）Output current measuring circuit determines dI/dt.SSPC is typically designed to read about the 600% of their rated current
Function could be realized in expected environment.Arc fault under high voltage produces only 5% current disturbing of the about rated current.
Therefore, arc fault disturbance is likely difficult to separate with the normal noise of circuit.SSPC often uses shunt resistance device as measurement
By the device of the electric current of its terminal, these shunt resistance devices set size according to scope above, it means that defining can
Signal to noise ratio for arc fault detection.Shunt resistance device shows well, but as voltage improves in low voltage application, loses
Go the ability that the normal noise by arc fault disturbance and circuit is distinguished.Particular example can be combined to illustrate this problem.
In high-voltage system, the change in output current is caused to be reduced according to equation below because of series arc faults：
In modern environment, typical arc fault event will cause 20 vor signals.In 28 volts of DC systems, 20 volts of strings
Current reduction during connection arc fault event obtains following relation：deltaI / ILOAD = 20 / 28 = 0.714 =
71.4%.But in 270 volts of DC systems, the current reduction during similar 20 volts of series arc faults events is obtained such as ShiShimonoseki
System：deltaI / ILOAD = 20 / 270 = .074 = 7.4%.In exemplary currents monitoring system in SSPC, measurement
Scope typically covers the 0% to 600% of rated current.Rated value is reduced to load current value by the Several Typical Load for being applied to SSPC
75% near, therefore it is presumed that under 270 volts of DC line voltage due to curent change caused by series arc faults be 75% load electricity
The 7.4% of stream, and be only only 5.6% current value of 600% full journey scope.By contrast, in 28 volts of DC systems, rated value is reduced
Load current be 53.6%, it is almost big 10 times.5.6% current value proportional to 600% scope is only 600% full journey scope
0.93%, it is 8.9% for 28 volts of systems by contrast.In 0.93% curent change and SSPC caused by this series arc faults
The precision of circuit monitors system is in same order.The change of 28 volts of systems is higher on value.Therefore, although 28 volts of DC systems
Arc fault event in system easily determined using shunt resistance device, but for the arc fault thing in 270 volts of DC systems
Part is not same.
It is the AC contents to providing the DC signals of power to fixed load merely to realize the information needed for arc fault detection.Cause
This, can ignore the DC contents of signal, and can use the AC coupling features of transformer.Because the DC electric current electricity in the system
Flat height, so while the typical current transformer based on iron core can not be used the reason for magnetic core saturation.The hollow unsteady flow of PCB instantiations
Device will not saturation, and therefore solve this problem by ignoring any DC electric current component and directly providing dI/dt.
