ELECTRONIC INSTRUMENTATION FOR TESTING OF INSTRUMENT TRANSFORMERS

Abstract

"e v,crk presented in this roport is a contribution toiardr using electr,nion devices for 1nstrtr+ent transforor tosting. An tnstrunnt for testtn of currant trsnstr r has boon designed develop d and tested. The basic principle in same t s generally used for comparinion method but the costly vsrinb1e mutual inductance is replaced by electronic devices, Mt al ectronic detector htch is a part of the instrument and con be used separately for other purposes also has been desti& q developed and tested. The test results aro given. Wt i some modification given in the report the instrument can be used forPotential transformer tooting also. A seberi► is also proposed for an automatic .ectronic instrument for Instrument trnnsf,r r tasting.
