Switched Busbar Module
Product Code : LSK-EPS-10520
Switched Busbar Module (SKU LSK-EPS-10520) is a fully instrumented trainer from the Modular Power Systems range that simulates industrial busbar switching, monitoring and protection on a double busbar and a radial feeder system. It suits B.Tech/B.E. electrical switchgear and protection labs and final-year projects. Through Science Lab Supplies, a laboratory equipment supplier in India based in Ambala, colleges, institutes, contractors and distributors can obtain it on one quotation.
Specifications
Each part of the busbar module has its own row in the table. In short, the lower panel carries a sectioned main and standby bus with six bi-directional feeders, the upper panel a radial system with four feeders, and current transformers on every bus and feeder allow zone protection.

Applications and Experiments for the Switched Busbar Module
With the module, students can transfer load between main and standby buses, apply faults at chosen points and watch the relays isolate them, covering bus switching, zone protection, fault recording and switching transients as focused engineering lab equipment for switchgear courses.
- B.Tech switchgear and protection lab: high-impedance differential busbar protection and bus transfer.
- Line/line and line/earth faults; earth fault protection can also be studied with the Overcurrent And Earth Fault Relay.
- Interruption transients with the point-on-wave breaker; fuse and breaker behaviour is covered by the Circuit Breaker Trainer.
Run high-current fault tests only under qualified supervision.
Standard Scope of Supply
Supplied with the module are the relay software, a set of shrouded leads and a user guide with equipment descriptions, theory and experiments. Not included: a computer for relay programming, the additional protection relay for the spare socket, and external loads for the test points.
Packing, MOQ and Lead Time
Request a quotation for a single module or for a full Modular Power Systems laboratory. It will list packing, delivery time and price for the chosen quantity, and supply and load modules from the same range can be included on the same document.
Using its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). A busbar protection bench can be priced via the contact page, the enquiry cart or, for public bids, the lab tender page.
Frequently Asked Questions
Can the feeders act as sources and loads?
Yes. The six lower-panel feeders are bi-directional, so each can be set as incoming or outgoing and connected to supply or load modules of the Power Systems range.
Is a computer needed to set the relays?
No. Relays can be set from their local control panel. A cable link to a suitable computer, using the included software, is optional; the computer is not included.
Who supplies the Switched Busbar Module?
Science Lab Supplies in Ambala, India, quotes the module by itself or within a complete power systems laboratory, with the shrouded leads, relay software and user guide shown on the same quotation.
What records do the relays keep?
The protection relays monitor and measure fault events and disturbances, so after each applied fault students have recorded data for fault analysis and for comparing relay settings.
