Analysis and Handling of a Case of Patch Panel Fracture Fault Encountered by a 500 kV Line CVT
Capacitor voltage transformers(CVT)are important electrical equipment in substations,through which high-voltage lines are connected to voltage regulating devices,power meters,protection devices and other equipment.Once an accident occurs in plants or substations,the aforementioned equipment will not work properly without reliable voltage sig-nals provided by CVT.This paper analyzes the cause of a CVT high-voltage patch panel fracture fault in a power plant and formulates a treatment plan,which may provide useful information for safe and stable operation and maintenance.
