Simple Method of Measurement Variation in Current Transformer Acceptance Test

Introduction was made to two methods for current transformer acceptance test measurement variation, that is to say current method and voltage method; the test data, calculation results and errors of voltage method to measure current transformer variation were given out, it is raised that to use voltage method for acceptance test of current transformer variation is a simple, practical and convenient test method. Experimental results show that to use voltage method to measure current transformer＇s variation is completely feasible, with certain accuracy.
