Protection Relay Test Set
Product Code : LSK-EPS-10525
Protection Relay Test Set (SKU LSK-EPS-10525) is a desk-style test station that gives students theoretical and practical experience with a range of industrial protection relays adapted for educational use. It lets them compare relay characteristics and connect two relays together for discrimination studies, and it serves switchgear and protection labs in B.Tech/B.E. electrical engineering. Colleges, universities, tender contractors and distributors can buy it through Science Lab Supplies, with quotations issued from Ambala, India.
Specifications
The relay test set specification is split into single rows below. In short, meters, CTs, VTs, power supplies, a configurable transformer and load resistors sit behind a front panel of test circuits, with an upper-panel transmission line, lower-panel controls and relays in enclosures resting at either end of the desk.

Applications and Experiments for the Protection Relay Test Set
With the test set, students can set up fault circuits on the front panel, program a relay and record how it operates for different currents, voltages and settings. With two relays connected they can study discrimination, and with the upper-panel line, distance protection.
- B.Tech switchgear and protection lab: characteristics of individual relays, as later applied in the three-relay Distribution Trainer.
- Relay discrimination with two relays in the same circuit.
- Distance protection and parallel feeder tests on the transmission line; generator protection through CTs and a VT is covered on the Salient Pole Generator.
- Programming relays directly or with the support software.
Test currents and voltages are derived from the mains; tests should be run under qualified supervision.
Standard Scope of Supply
The test set is supplied with its meters, CTs, VTs, power supplies, configurable transformer, load resistors, transmission line panel, multi-core relay cables, schematic diagrams and relay support software. The specific relay modules and the computer are confirmed on the quotation.
Packing, MOQ and Lead Time
Ask for a quotation for the test set alone or together with the relay modules you plan to study. It will show packing, delivery time and price for each line item, which makes budgeting a complete protection laboratory straightforward for your department.
With an Importer-Exporter Code in place, Science Lab Supplies can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Relay lab requirements can be described through the contact page or gathered in the enquiry cart, and bids under a tender are covered on the lab tender page.
Frequently Asked Questions
Which relays are used with the test set?
Each relay comes in a rugged, portable enclosure that rests on the desk at either end of the test set. The exact relay modules for your laboratory, such as overcurrent, feeder or distance relays, are confirmed on the quotation.
Can two relays be tested together?
Yes. Two relays can be connected for experiments such as relay discrimination, with one resting at each end of the desk area and each fed by its own multi-core cable.
Who supplies the Protection Relay Test Set?
Science Lab Supplies quotes the test set from Ambala, India, and the relay modules you plan to study, along with load banks or other power system trainers, can be priced alongside it.
How does the configurable transformer help?
Its star-connected primary and multi-tapped secondary let students connect it as delta or star at different voltage ratios, giving varied test conditions for the relays.
