Switched Busbar Module Manufacturer,Supplier and Exporter in India
Product Code : EL-EPP-11348
The fully instrumented unit includes two main control panels: the upper panel and the lower panel. Each panel has a detailed mimic diagram.
The lower panel has a double bus: a main bus and a standby bus or reserve bus.
Each bus has two sections, split by circuit-breakers. Each bus includes individual bus section switches.
Two bus-coupler switches connect the left and right-hand sections of the main bus and the standby bus.
The lower front panel also includes six feeders.
They are bi-directional, so the user can set them as incoming or outgoing feeders.
The feeders connect to the other modules of the Power Systems range.
One feeder includes a point-on-wave circuit-breaker.
This allows the user to study the transients created when an alternating current is interrupted (switched).
The main bus, the standby bus and all feeders include current transformers (CTs).
The user connects these to the protection relays to create zone protection circuits and investigate faults applied to different parts of the double busbar system and the radial system. This is high-impedance differential protection.
Each feeder also has its own circuit-breaker and meters to measure and display the current and voltage at each feeder.
The upper panel has a radial system of one incoming and three outgoing feeders. Each feeder includes a circuit-breaker, voltage and current meters, and current transformers for connection to the protection relay. The upper panel also includes test points for the double busbar and radial systems.
The user connects and sets the protection relays to detect line and earth currents, voltage and frequency faults.
The relays also monitor and measure fault events and disturbances for fault analysis.
The user sets the relays from their local control panel, or by a cable link to a suitable computer and software (included).
When the user applies a circuit fault, the relays open circuit-breakers in the test circuits. The circuit-breakers also include hand-operated switches, and lamps. The lamps show whether the circuit-breakers are open or closed.
For more experiments in protection, the unit has an extra socket to connect an additional protection relay.
Supplied with the equipment is a set of shrouded leads for the user to connect the test circuits together.
The unit includes an emergency switch, a mains supply isolator and protection fuses.
