EFFECT OF MAGNETIZATION ON INSTRUMENT TRANSFORMER ERRORS

Karel Draxler – Renata Styblíková

   Errors of the instrument current and voltage transformers, caused by waveforms with non-zero DC component were measured and analyzed these are discussed in brief, for a case of nanocrystalline-tape-wound toroidal core.

Keywords: instrument transformer, ratio error, phase displacement, impulse magnetization, DC magnetization
