Abstract
A fault managed power method and system are provided, which includes a source, downstream component(s) and a power cable for delivering electrical energy, including electrical pulse(s) or DC current/voltage and electrical pulse(s), from the source to the downstream component(s). The cable is isolated from upstream and downstream noise or signals using low-pass filters, which are arranged upstream and downstream of the power cable. The method and system can measure electrical activity on the cable using an impedance sensor tank circuit; detect for an electrical disturbance on the cable corresponding to an occurrence of a fault resulting from body contact with the cable or other faults, based on the measurements from the sensor, when the pulses or the DC current/voltage and pulses are supplied to the cable; and in response to detection of the occurrence of the fault, interrupt the supply of electrical energy to the cable, via an upstream switch(es).
