Classification | Types of Protective Relays

Over–under Voltage RelaysDirectional RelaysCurrent- Or Voltage-Balance RelaysDistance RelayingDifferential RelayingPilot Wire RelayingThe over-under voltage relays have characteristics similar to the overcurrent relays. The actuating quality in the operating element is voltage instead of current. Voltage relays often combine the under–overvoltage elements in one relay, with contacts for either an undervoltage or overvoltage condition. These relays may be used to trip the breakerSee more on yourelectricalguide Electronics Hub
