ABSTRACT:
A current limiting circuit arrangement is disclosed herein and includes a pair of parallel connected circuits, preferably identical circuits, each of which includes series connected conductive and capacitive reactance tuned to resonate at a given frequency. The arrangement also includes means, preferably a single voltage transformer, for maintaining the voltage across the capacitive reactance in one circuit and the voltage across the capacitive reactance in the other circuit equal and means for detuning these circuits, that is, taking them out of resonance in response to a predetermined condition.
