Abstract

The problem of correcting the results of no-load loss measurements of power transformers for the effect of distorted supply voltage waveform on the magnetic flux in the core and hence on both the hysteresis and eddy current loss components of core losses is presented. The instrumentation requirements for no-load loss measurements to ensure proper application of the correction formula are described.
