Product Code : SCL-EELE-12858
Indian Lab Suppliers supplies the Feeder Management Relay Trainer (Numerical) (Product ID: 12858) as part of its electronics engineering lab equipment range. It is a protection trainer built around a numerical feeder management relay covering over-current, voltage, frequency, earth-fault, sequence and breaker-backup functions.
Quick Answer
The numerical feeder relay (1 A / 5 A, USB PC link and setting software) is tested with three voltage and current injector panels, three variable voltage panels (0-270 V, 1 A) and three over-current and elapsed-time panels with 1 ms resolution. Six 5/5 A CTs, a 415/110 V, 50 VA star/star voltage transformer and a three-phase multifunction meter complete the measuring side. Experiments cover IDMT over-current, under- and over-voltage, under- and over-frequency, earth fault, negative-sequence over-current and over-voltage, zero-sequence over-voltage and local breaker backup (LBB). The input is a 415 V three-phase DOL starter panel, so tests must be supervised by qualified staff.

Frequently Asked Questions
Which protections can be tested?
Over-current, voltage, frequency, earth fault, sequence protections and LBB.
What is LBB?
Local breaker backup, which trips upstream breakers if the local breaker fails to clear a fault.
How is the relay configured?
Through USB with the setting software.
