Prok devices pvt ltd an iso 9001-2008 company introduces digital microprocessor micro controller based idmt definite time instantaneous earth fault relay (efr). It is a current sensing device which is semitropical professionally designed and tested for protection of generators, transformers and feeders. Prok dv's make digital microprocessor micro controller based idmt definite time instantaneous earth fault relay (efr) can be employed with various earth fault protective schemes

Features Software based design ‘Block on Start’ feature provides very accurate overload protection Definite time over load protection Locked rotor current protection Single phasing protection Wide setting ranges Draw -out case Principle of Operation: This is a Microprocessor based relay which has been designed to sense the load currents in all the three phases of an AC motor. It monitors the levels of these currents continuously, giving output signals for relay and LED driver circuits.

We are offering numerical directional over current relay. Features programmable characteristic angle programmable operating characteristics high speed directional control low burden trip test facility.

ARGUS 7 is a combined check and system synchronising relay which can automatically select check or system synchronise from measurements of the relative phase angles between line and bus voltages. The relay will prevent closure of the circuit breaker if either the phase angle, slip frequency or the voltage magnitude of the incoming and running voltages fall outside prescribed limits.If the parameters are within the limits the relay will issue an output which can be used to close the circuit breaker directly or in conjunction with an autoreclose scheme. Both the check and system synchronise functions have independent settings and blocking features. The relay includes split system detection with a variable time delay, which can be used for blocking purposes within delayed autoreclose schemes.Synchronising bypass logic is provided to connect a dead line or bus to a live line or bus. For manual synchronising the relay includes a circuit breaker close guard feature which is used to prevent the control switch being held closed during a synchronising operation. This feature is implemented using internal logic and removes the need for an external relay. Application Check-synchronizing System-synchronizing

Prok dv's make Digital microprocessor/microcontroller based Earth Leakage Relays (ELR) withCore Balance Current Transformer (CBCT / ZCT) are used to detect leakage currents inelectrical power systems. ELR transmits a signal to activate the trip coil of theMCCB/ACB/OCB/CONTACTOR in the event of earth leakage resulting in automatic isolationof the load. ELR have been widely used and accepted because of field adaptability andare economic.Prok dv's make Earth Leakage Relay (ELR) MPEL series uses the state-of-the-art, Digitalmicroprocessor/micro controller based protection device to detect low level leakage dueto degradation of insulation of phase conductors or high impedance faults.The main featureof Digital microprocessor/microcontroller Earth Leakage Relay (ELR) continuous display ofearth leakage currents of the power system. The unit has immunity to external disturbancelike harmonics and transients. Specification Frame leakage protection for LT control panels and switch boards. 8 character 2 line LCD displays with back-lit. Test & Reset facility. CBCT / ZCT connection monitoring facility. Trip Circuit Failure indication. Immune to harmonics and transients. Tropicalized and rugged design.

We bring forth to the clients a comprehensive range of overload relays that is fabricated from superior quality raw materials because of which they are in high demand in various industries. To maintain the standard of these relays we utilize advanced technology machines to produce it. Utilization of latest technology parts in the overload relay it ensures efficiency and durability. the performance of a starter depends on the reliability of the relay. This unit consists of a triple pole, bimetallic relay housed in a sealed bakelite enclosure. It is of the manual resetting type, which unmistakably indicates tripping due to overload. After tripping on an overload, the relay has to be reset by pressing the ‘stop’ button. the relays can be reset only after the bimetals have cooled sufficiently after tripping on an overload, thus also allowing the motor to cool down. A wide range of relays with easily adjustable current settings are available. all over load relays are individually tested on a automatic test bench to ensure foolproof operation .whenever there’s an over load due to load conditions or drop in supply voltage the relay will trip ,disconnect supply and protect your motor from dangerous overheating or burning out. Praised for : trouble-free operationcorrosion resistanceeasy installationability to withstand adverse conditions used for : protecting the motors from damages caused by overload or electrical faults
