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. It serves switchgear and protection labs in B.Tech/B.E. electrical engineering. Science Lab Supplies can supply it from Ambala, India to colleges, universities, tender contractors and distributors.
Specifications
The test set combines meters, current and voltage transformers, power supplies, a configurable transformer and load resistors with a built-in desk area. Relays in rugged portable enclosures sit at either end, fed through multi-core cables, while an upper-panel transmission line supports distance and parallel feeder tests.

Applications and Experiments for the Protection Relay Test Set
Students 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 study discrimination; with the upper-panel line, distance protection. It turns protection theory into repeatable bench practice.
- B.Tech switchgear and protection lab: characteristics of individual relays.
- Relay discrimination with two relays in the same circuit.
- Distance protection and parallel feeder tests on the transmission line.
- 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, which makes budgeting a protection laboratory straightforward.
With an Importer-Exporter Code in place, Science Lab Supplies can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Our enquiry cart and contact page handle requests, and the lab tender page explains tender supply.
Frequently Asked Questions
Which relays are included with the test set?
Relays are supplied in rugged portable enclosures that rest on the desk. The listing does not fix which relay types come as standard, so please confirm the set you need through the contact page.
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.
Who supplies the Protection Relay Test Set?
Science Lab Supplies supplies it from Ambala, India, and can quote the relay modules alongside it.
How does the configurable transformer help?
Its star primary and multi-tapped secondary let students connect it as delta or star at different voltage ratios for varied test conditions.
