Apparatus and method for identifying the location of a fault in a shunt capacitor bank

摘要

Apparatus and method for identifying the location of a fault in a bank of shunt capacitors. # Apparatus and method is disclosed for identifying the location of a fault in a bank of shunt capacitors. The apparatus includes a sampling circuit for sampling current signals or voltage associated with the bank of shunt capacitors. A microcontroller is coupled to the sampling circuit and programmed to measure a phase angle offset of the sampled signal neutral point, and comparing the phase angle neutral point offset by a fixed phase angle reference. The method includes sampling a current signal or voltage associated with the bank of shunt capacitors, determining a phase angle compensated neutral point, and comparing the phase angle neutral point offset by a phase angle of fixed reference.
