Analysis and Treatment of Voltage Anomaly of Protection Measuring and Controlling Device of an Actual Factory Building
Voltage transformer is important electrical equipment in power system,which plays pivotal role in the meas-urement of line voltage,power and protection and the connection of motors to the grid.Faults caused by secondary wiring errors of voltage transformers often occur during the operation of newly built and retrofitted power stations.This paper analyzes the cause of abnormal voltage display after changing transformer's connection mode,and reports the effective countermeasures adopted.
