HIGH-IMPEDANCE BUS DIFFERENTIAL PROTECTION

HIGH-IMPEDANCE BUS DIFFERENTIAL PROTECTION

A system for high impedance bus protection that includes a safety module to divert excess current away from a protective element of an intelligent electronic device. The safety module may include a variable resistor and a bypass relay in parallel across secondaries of one or more current transformer...

Zusammenfassung:A system for high impedance bus protection that includes a safety module to divert excess current away from a protective element of an intelligent electronic device. The safety module may include a variable resistor and a bypass relay in parallel across secondaries of one or more current transformers. The bypass relay may be configured to close upon detection of excess current through the secondaries to divert the excess current away from the variable resistor and the protective element.
