Fault Simulation and Analysis of Abnormal Break Phase for Inductor of Electric Energy Measurements

Based on the theoretical analysis of the inductor of electric energy measurement under the faults of break phase, models of a three-phase three-line inductor of electric energy measurements in a practical 35kV high voltage power system were established by using Matlab/Simulink. The performances of the inductor of electric energy measurement under both the normal operation and different faults of the break phase were simulated and analyzed. The proposed models were demonstrated by comparison with the measuring data and the theoretical analysis. Applying to the models, the abnormal data of a factual inductor of electric energy measurement was proposed and judged perfectly by fault simulation, which was helpful to solve the practical engineering problems.
