Kev soj ntsuam ntawm kev txhaum ua cov nyiaj tau hluav taws xob capacitors thiab kev tiv thaiv kev ntsuas

The compensation power capacitor, as an important reactive power compensation device in the power system, plays a crucial role in improving the power factor and voltage quality. However, in actual operation, compensation power capacitors frequently experience failures, which seriously affect the safe and stable operation of the power system. According to statistics, compensation power capacitor failures account for 15% to 20% of the electrical equipment failures in the Kev faib tawm txoj kab ke .
