Product Code : SCL-EELE-12792
Indian Lab Suppliers supplies the Distance Protection Relay Kit (Product ID: 12792) as part of its electronics engineering lab equipment range. It is a rack-mounted trainer for studying transmission-line models and numerical distance protection, including fault tests and auto-reclose.
Quick Answer
Eight ABS panels with mimic diagrams sit on a 40 × 40 mm aluminium profile rack, with every input and output on 4 mm shrouded sockets. A numerical distance relay (1 A/5 A) with trip and auto-reclose contacts, RS-232 PC setting software and a USB converter protects a simulated transmission line built from a 10 Ω/600 W resistor, six 0.15 H/5 A inductors and six 2.2 µF/630 V capacitors, arranged as short, medium (125 km) and long (250 km) line models. Supporting panels include a DOL starter (4 A four-pole MCB, 9 A contactor, 1.4–2.3 A thermal overload relay), two bidirectional three-phase multifunction meters with RS-485 Modbus RTU, six 5/5 A CTs, a 415/110 V star/star transformer, a forward/reverse switch, single-phase supply outlets and a 3 × 600 W switched resistive load. The trainer works at 415 V three phase; use earthing and qualified supervision, and keep clear of the fan-cooled resistors, which run hot.
