  • The loss of mains relay type LMR-111D forms part of a complete DEIF series of relays for protection and control of generators. A mains failure will be detected, provided a disconnection at an arbitrary point of the network results in a swift change of the generator frequency (vector shift). An opening signal is then transmitted to the mains circuit breaker, and the generator will thus be protected against damages caused by an automatic reconnection to the high-voltage network. Relay outputs : The LMR-111D is provided with two output contacts (with common set points), either normally energised or normally de-energised. The contacts may be set to open or to close on activation. Normally energised contact : Recommended for warning and alarm purposes. In case of an auxiliary supply drop-out, the contact is immediately activated. Normally de-energised contact : Recommended for regulating and control purposes. An auxiliary supply failure will not result in an unwanted activation of the contact. Power-up circuit : The relays are provided with a 200 ms power-up circuit, ensuring the correct function of the relay on connection of the auxiliary voltage. Features : - Detection of vector shift - Mains disconnection on mains failure - Ensures no asynchronous reconnection - LED indication of fault condition - LED indication for activated relay - 35 mm DIN rail or base mounting Borna Niroo Karan (Bornika) is the exclusive agent of DEIF in the fields of consultation , sales and distribution of power industry products including Loss of mains relay products .
