Switched Busbar Module Manufacturer,Supplier and Exporter in India
Product Code : EL-EPP-11348
Quick Answer: The Switched Busbar Module is a fully instrumented unit with a double busbar system on its lower panel and a radial system on its upper panel, each with a detailed mimic diagram. Current transformers on every bus and feeder connect to protection relays for zone protection and fault studies.

Key Features
- Lower panel: main and standby (reserve) bus, each in two sections split by circuit-breakers, with bus section switches and two bus-coupler switches
- Six bi-directional feeders that can be set as incoming or outgoing and connect to other Power Systems modules
- One feeder with a point-on-wave circuit-breaker for studying switching transients
- Upper panel: radial system of one incoming and three outgoing feeders, each with circuit-breaker, voltage and current meters and current transformers
- Protection relays detect line and earth current, voltage and frequency faults and record fault events; set locally or from a computer with the included software
- Extra socket for an additional relay; shrouded leads, emergency switch, mains isolator and protection fuses

About This Product
Students switch circuits between busbars and feeders as an operator would, then apply faults to different parts of the double busbar and radial systems to see how zone protection isolates them. The point-on-wave breaker adds the study of transients when an alternating current is interrupted.
Frequently Asked Questions
Can the feeders on the Switched Busbar Module be used as incoming or outgoing?
Yes. The six feeders on the lower panel are bi-directional, so each can be set as an incoming or outgoing feeder.
What type of busbar protection can be studied?
High-impedance differential protection: the current transformers on the buses and feeders connect to the protection relays to form zone protection circuits.
