IFV Time Delay Voltage Relay

The Type IFV relays are single phase induction disk relays designed to respond, with time delay, to an increasing voltage. Some models are frequency compensated, and some include an instantaneous unit (hinged armature type).

Applications

AC generators

Ungrounded three-phase distribution system

Protection and Control

Time delay overvoltage

Ground detection on ungrounded systems and equipment neutrals
