Sažetak
In this paper, a new test circuit is proposed for overvoltage testing of capacitors based on a motor-driven regulating transformer. Motor drives tap selector which is designed to ensure good electrical contact and low wearing. Keeping the test circuit close to resonance requires lower power rating of regulating transformer. Test circuit is capable to generate overvoltage waveforms according to IEC 60871-1 without use of circuit breakers. A software was developed for evaluation of recorded overvoltage waveforms considering amplitude and time limits. The efficiency of test circuit is demonstrated on an actual overvoltage test performed on MV capacitor.
