Abstract

For assuring safe and reliable operation of the high voltage shunt capacitor bank

in this paper

the influence of discharge coil on the capacitor voltage protection is studied. The mechanism of capacitordifferential voltage and unbalance voltage protection is introduced and the function of the discharge coil isdescribed. The causes of capacitor voltage protection action caused by discharge coil failure are analyzedby two practical cases. The fault finding method of capacitor voltage protection action trip is summarized.The test suggestions of the discharge coil at such three stages as hand over tests

normal prevention and aftervoltage protection action are proposed.
