Abstract
Aiming at the problem of the test data occur shift when dielectric loss factor measurement of voltage transformer of 220 kVⅠbus bar in Guandi Substation, based on principle of ferro-reso-nance, analyzes the influence of ferro-resonance phenomenon of cascade type voltage transformer on dielectric loss factor measurement, puts forward feasible solution.The application result shows that it is a simple and effective solution using standby dynamo supply voltage source to the test instrument.关键词
