Transverse Interference Voltages on Secondary Protection Wiring at Substations

Wiszniewski, A (Wroclaw University of Technology, Poland) ; Marczonek, S (Wroclaw University of Technology, Poland)


Abstract: This paper presents simple equivalent circuits which enables calculation of expected values of transverse interference voltages on various secondary circuits at Substations. The transverse voltages appear only if there is an asymmetry in secondary circuits. They may cause damages of insulation or maloperation of protective devices. On the basis of the equivalent circuits, the efficiency of means which may be adopted for suppressing the transverse voltages are discussed.

Keyword(s): transverse interference voltages ; asymmetry ; protection
