Abstract

Affected by various factors, the result of shunt capacitor of breaker dielectric loss measurement is easily misjudged. In order to avoid misjudgment, this paper analyzes the common three kinds of influence factors: interference signals in the site, Cardon effect and air humidity. Three methods were proposed to reduce these effects, they are frequency conversion and anti-jamming technology, increasing the test voltage and spraying RTV. The results show that these measures can effectively avoid the miscarriage of justice of the test results.
