Analysis and Countermeasures of an Internal Fault Encountered by an Actual 500 kV Capacitive Voltage Transformer
Voltage transformers are common equipment in power systems,and their role is to convert high-voltage signals into low-voltage signals for measurement,protection,and control.This paper entails a case analysis of an internal fault encountered by an actual 500 kV capacitive voltage transformer,and the countermeasures proposed for preventing capaci-tive voltage transformer internal faults.
