Generator Protection Relay Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12793
Indian Lab Suppliers supplies the Generator Protection Relay Trainer (Product ID: 12793) as part of its electronics engineering lab equipment range. It is a modular rack trainer for testing the protection functions used on generators and feeders with a three-phase numerical relay, current and voltage injectors and timers.
Quick Answer
Fourteen slide-in ABS panels with mimic diagrams sit on a 30 × 30 mm aluminium profile rack, and all connections use 4 mm shrouded sockets and cables. Test signals come from two single-phase current injectors (0–200 V/3 A and 0-2-8 V AC/12 A) and a voltage injector (0–270 V/1 A from 230 V), and two elapsed-time counters with 1 ms resolution record the relay operating time. The three-phase numerical feeder-manager relay (1 A/5 A, 2 NO and 2 NC trip contacts, USB PC interface) is studied for IDMT overcurrent, under/over voltage, under/over frequency, earth fault, negative-sequence overcurrent and overvoltage, zero-sequence overvoltage and local breaker backup. The supply panel is 415 V three phase with a 10 A four-pole MCB, 9 A contactor and 1.4–2.3 A overload relay; the trainer must be earthed and used under qualified supervision.
