【Abstract】 The methods and corresponding criteria for judging the wiring correctness of zero sequence circuit of microprocessor\|based protective relaying for HV transmission line are given. The following problems concerning the criteria are analyzed theoretically.(1) wiring principle of zero sequence circuit of microprocessor based protective relaying for HV transmission line. (2) judgment of grounding terminal in open delta connection of PT secondary winding. (3) judgment of wiring correctness of zero sequence circuit by use of the sampling report.更多还原
