Features Programmable for 1A / 5A relay rating 3 OC + 1 EF + 1 SEF/REF Choice of 6 IDMT curves and definite time Trip test facility History of 6 latest faults along with settings Self supervision facility MODBUS open protocol over RS – 485 port MODBUS protocol over RS – 232 port Draw out facility with inbuilt CT shorting Standard dimension – 144mm x 144mm Principle of Operation: The relay measures the line current from each of the line CTs and if the current exceeds the set threshold, then relay extends a trip signal after an operating time. The relay's “operating time” is determined by selecting “definite time” or one of the six “inverse time” characteristics. Input to sensitive earth fault protection can be connected in two ways. First one the residual current derived from three phase current transformers, and second is low output core balance current transformer can be connected. Input to restricted earth fault protection will be derived from neutral CT output with external stabilizing resistor. Phase over current, Earth fault, Sensitive earth fault/Restricted earth fault protections* features can be made active or inhibit independently.

Being a client-centric organization, we are engaged in manufacturing, supplying, exporting and trading Numerical Over Current Relay. Based Over Current Relay (OCR) with Earth Fault Relay (EFR), these relays are extensively used for selective over current. Apart from this, applicable in substations and industrial networks, these relays are widely used for earth fault protection of radial feeders in impedance earthed power systems.

The micro-controller continuously monitors the magnitude of the phase current andthe neutral current .whenever the phase current or the earth current magnitude exceeds thepresent value corresponding line / earth element will pick up and relay will trip after timeinterval calculated by the selected IDMT curves. Whenever the fault level exceeds theselected high set range, the relay will trip for high set, ignoring the selected IDMT curves. Thetimer logic is processed and after comparison with set time schedules, tripping signals areissued accordingly. There are two output relays , each output relay has two change overcontacts either for alarm or tripping. The output relays are programmable.The relay rating (In) is field selectable either 1A or 5A. The relay has RS 485 com port which canbe used with modbus protocol for communication purposes.

The circulating current relay IRXm is mainly used for high-speed restricted earth fault protection of generators and transformer windings. For the selective detection of faults, current transformers in summation connection are employed with an external stabilizing resistor for high impedance method of measurement. The relay is provided with a band-pass filter which suppresses harmonics and DC components of the input current. The relay is suitable for current transformers with secondary rating of both 1A and 5A.
