Simulation of differential current protection schemes involving multiple current transformers and a varistor

This paper presents the simulation of multiple current transformers (CTs) operating in parallel into a common spill circuit. The voltage across the spill branch in the high impedance case can be quite high and a varistor (MOV) may be placed across the spill branch to keep this voltage within safe li...

Zusammenfassung:This paper presents the simulation of multiple current transformers (CTs) operating in parallel into a common spill circuit. The voltage across the spill branch in the high impedance case can be quite high and a varistor (MOV) may be placed across the spill branch to keep this voltage within safe limits.
