摘　　要：在变压器微机保护中,比率差动保护的校验往往成为调试的难点。本文对变压器差动原理和相位补偿进行了总结。并以Y/Y/△-11型三绕组变压器及南瑞RCS978保护为例,从正反两方面对变压器比率差动曲线的校验进行了阐述。IN transformer microcomputer ,the ratio diffirential motion protection verification often become the debugging the difficuty.This article has carried on the summary to the transformer diffirential motion principle and the phase compensation.And take Y/Y/△-11 3type winding transpormers and the protion of the RCS978 as the example,has carried on the eleboration from the pro and con two aspects to the transformer ratio diffirential motion curve verification.
