The type KV-1 is a high-speed single phase undervoltage relay particularly suited for applications where high drop-out ratio is desirable.
This relay may be used for high-speed carrier tripping or carrier starting for phase fault clearing of a weak-feed terminal.
Hot-Line reclosing is another application for this relay.
