SYSTEM, APPARATUS AND METHOD FOR DETECTION OF ELECTRICAL FAULTS

摘要

System for monitoring an electrical system of a facility includes one or mor e local sensing devices, each of which is adapted to be connected to the electrical system of the facility in proximity to a respective load that receives power from the electrical system so as to make local measurements o f a voltage across the load continuity measurements of electrical-power presen ce at one or more points in the electrical system of said facility. A processin g unit is adapted to receive and compare the local measurements to reference measurements of the voltage supplied to the facility, in order to detect a fault in the electrical system.
