Abstract

As for the primary structure for each phase of shunt capacitor bank of certain substation with double-bushing discharging coil

the zero sequence voltage is needed as the wiring mode of voltage differential protection initial circuit of shunt capacitor bank.In this paper

features of such method and its shortcoming in actual operation and maintenance are analyzed;the scheme on inter-phase voltage differential protection is raised for reference by related technical persons.
