Prok Devices Pvt. Ltd. Only Indian Company to manufacture Micro-controller/Processor based Numerical Over Current and Earth Fault relay with IDMT (Inverse Definite Minimum Time), Definite Time & Instantaneous trip time characteristics in a single unit.
It is a non directional relay, which can be employed as protection against over current in any of the 3-phases and earth. The relay has the option for selecting any one of the - 7 IDMT Curves for Phase Faults and Earth Faults.
The IDMT-curves incorporated are:
1. Normal Inverse.
2. Extremely Inverse.
3. Restricted Inverse.
4. Very Inverse.
5. 1.3 Seconds.
6. 3.0 Seconds.
7. Long time delay.
Other important features are:
2 line 16 characters LCD display (with back-lit), for user friendly selection of the characteristics, to indicate nature of fault, to display of magnitude of the fault current and entry of required parameters.
LED indications for power ON, pick-up, low set trip (l>/le>) and trip for high set(l>>/le>>) in the front fascia.
Membrane keypad for accessing of the relay, selection of curves and parameters.
The relay has high drop-off / pick-up ratio and has non-volatile memory for data retention and retrieval.
The casing is of Modular Integration Draw Out System (MIDOS) with automatic CT shorting facility. The Auxiliary supply range is 30 - 130 V DC or 85 to 275 V AC / DC.. The unit is tested at CPRI as per IEC - 60255 / 60068 standards. The dimension of the unit is : 155 x 177 x 246 mm (W x H x D).
