Abstract
In view of a case of backup protection of main transformer caused by improper implementation of voltage regulation measures
this paper combs the process of the shift adjustment of main transformer joint
analyzes the mechanism of the backup protection maloperation of main transformer after the shift adjustment
and analyzes the fault causes. At last the results are verified by simulation with PSCAD.
