  • The protective overload relay type RMP-111D forms part of a complete DEIF series of relays for protection and control of generators and is applicable to both marine and land-based installations. Also available are reverse power relays (RMP-121D) and combined overload and reverse power relays (RMP-112D). The RMP-111D is type-approved by major classification societies and is applied for protection of the prime mover against overload. This is especially required if the prime mover is undersized in proportion to the AC generator. Measuring principle: The relay measures all 3-phase currents and phase voltages. The TDM (Time-Division-Multiplication) principle ensures an accurate measurement of the RMS value of the power, irrespective of wave form and asymmetry. The RMP-111D is available with the following couplings: 2W3 2-element 3-phase 3-wire, unbalanced load 3W3(4) 3-element 3-phase 3-wire (4-wire), unbalanced load If the power exceeds a set point, the output is activated. The set point value is set on the front of the relay by means of a potentiometer. If exceeded, a fault signal is generated, and the associated yellow LED is lit. Relay outputs : The RMP-111D is provided with an output with a maximum contact, either normally energised or normally de-energised. The contact may be set to open or to close on activation. Normally energised contact : Recommended for land-based installations for warning and alarm purposes. In case of an auxiliary supply drop-out, the contact is immediately activated. Normally de-energised contact : Recommended for marine installations for regulating and control purposes. An auxiliary supply failure will not result in an unwanted activation of the contact. Features : ●Protection of prime mover ●3-phase measurement ●LED indication of alarm condition ●Timer-controlled tripping ●LED indication for activated relay Borna Niroo Karan (Bornika) is the exclusive agent of DEIF in the fields of consultation , sales and distribution of power industry products including Overload relay products .
