Discussion about the Way to Measure Capacitance and dielectric Loss of Circuit Breaker Capacitor
摘要
在预防性试验中
经常发现断路器端口并联的均压电容器介损超标问题
如果全部更换就会带来较大的经济损失。究其原因是选择的试验电压不当造成的
提高试验电压后
大部分电容器介质损耗趋于正常水平。所以
试验电压越接近额定电压结果越能表现其绝缘性能的真实性。
Abstract
In preventive tests
It was often found that the dielectric loss of grading capacitor of circuit breaker exceeded the specified value.This is the main reason that the selected test voltage is improper.Improving test voltage
the majority of capacitor dielectric loss tends to the normal level.Therefore
the closer the test voltage tends to rated voltage results
the more representation of authenticity of insulation performance.
