Feeder Management Relay
Product Code : LSK-EPS-10532
Feeder Management Relay (SKU LSK-EPS-10532) is a feeder protection relay presented in an educational format for studying the protection and monitoring of overhead lines and underground cables. It works with the Protection Relay Test Set in B.Tech and diploma power systems laboratories. Science Lab Supplies, a laboratory equipment exporter from India, supplies it from Ambala to colleges, training institutes, tender contractors and distributors.
Specifications
The relay sits in a robust enclosure with a carrying handle, mounts on the desk area of the test set and connects through a multi-core cable and safety leads. It combines four stages of directional or non-directional overcurrent with voltage, frequency and several earth fault functions.
| Parameter | Value |
|---|---|
| SKU | LSK-EPS-10532 |
| Overcurrent | Four independent directional/non-directional stages; first two settable to any of ten IDMT curves, last two direct time |
| Voltage functions | Under and overvoltage, residual overvoltage, negative sequence overvoltage |
| Earth fault | Directional/non-directional, sensitive directional/non-directional, wattmetric, restricted earth fault |
| Other functions | Negative sequence overcurrent, thermal overload, under and over frequency, broken conductor, selectable blocking, fault and disturbance records |
| Programming | Keypad and display, or software supplied with the test set |
| Supplied by | Science Lab Supplies, Ambala, India |
Applications and Experiments for the Feeder Management Relay
With fault circuits set up on the test set, students program the relay for a feeder and record how each protection element responds. Because it combines overcurrent, voltage, frequency and earth fault functions in one unit, a single relay supports several distribution protection practicals.
- B.E./B.Tech protection lab: directional and non-directional overcurrent on radial feeders.
- Sensitive and wattmetric earth fault tests for cable networks.
- Under/over voltage and frequency protection settings.
- Diploma electrical courses: reading fault and disturbance records.
Test circuits are mains-derived, so change connections with the supply isolated and run tests with a qualified supervisor present.
Standard Scope of Supply
You receive the relay module in its enclosure with carrying handle, programmable from its keypad and display. The Protection Relay Test Set, which carries the programming software, and a suitable computer are ordered separately; cables and any optional accessories are itemised on the quotation.
Packing, MOQ and Lead Time
A quotation can be prepared for one relay or for a set of protection relays with the test set. It shows packing, delivery time and price for the requested quantity, and other engineering lab equipment in India from this range can be added.

Frequently Asked Questions
What networks does the relay model?
It is intended for the protection and monitoring of overhead lines and underground cables, the two feeder types studied in distribution protection practicals.
How many IDMT curves are available?
The first two of its four overcurrent stages can each be set to any of ten IDMT curves; the remaining two stages use a direct time characteristic.
Who supplies the Feeder Management Relay?
Science Lab Supplies supplies the relay from Ambala, India, and can list it on one quotation with the test set and other power system modules.
Can it be used with equipment other than the test set?
Yes. Besides the Protection Relay Test Set, it is an optional ancillary for selected products in the power systems range; please name your unit when you enquire.
