Abstract Capacitor voltage transformers are important equipments in power network operation, which mainly consists of capacitive divider and electromagnetic unit. Because its structure in simple and many functions, they are widely used in the power system. Through test of CVT and disassembly inspection, it is proved that the main cause of lots of faults for the capacitive voltage transformer is the selection of raw material and manufacturing process. The paper mainly focuses on the working principle of the capacitor voltage transformers, analyzes the common faults of the capacitive voltage transformer secondary voltage. Finally, the suggestions for operation, maintenance and production of capacitor vohage transformers have been proposed.
