Product Code : SCL-EELE-12856
Indian Lab Suppliers supplies the Distance Protection Relay Trainer (Product ID: 12856) as part of its electronics engineering lab equipment range. It is a protection trainer for a numerical distance relay on a simulated transmission line, including auto-reclose.
Quick Answer
A line panel models a short, medium (125 km) or long (250 km) line from six each of 10 Ω / 600 W resistors, 0.15 H / 5 A inductors and 2.2 µF / 630 V capacitors, with two cooling fans. Six 5/5 A CTs and a 415/110 V, 50 VA star/star voltage transformer feed a numerical distance relay (1 A / 5 A) with trip and auto-reclose contacts, RS-232 PC link, a USB converter and setting software. Students apply LG, LL, LLG, LLL and LLLG faults, check that the relay trips on the faulted zone and see it reclose after a transient fault, with two three-phase meters recording the system. The trainer is supplied from 415 V three-phase through a DOL starter, so faults should be applied only under qualified supervision.
