Product Description
Part of the Modular Power Systems range, the Switched Busbar Module simulates industrial power line switching and monitoring. Important note: This unit has no test circuit supplies or loads. To use it correctly, it must be connected to two or more units in the Modular Power System Laboratory range. 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 (three on each side of the bus). They are bi-directional, so the user can set them as incoming or outgoing (sink or source) feeders. The feeders connect to the other modules of the Power Systems range (supplies and loads). Each feeder also has its own circuit-breaker and meters to measure and display the current and voltage at each feeder. 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 highimpedance differential protection. 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. These allow the user to connect faults or external loads (not supplied). The panel includes test/ fault switches, one with a digital timer. These allow the user to create open-circuit and short-circuit (line/line or line/earth) current faults and monitor their effects. 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 (computer not included) and software (included). When the user applies a circuit fault, the relays open circuit-breakers in the test circuits. The circuitbreakers 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 (not supplied). 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. The Modular Power System Laboratory allows experiments on power generation, transformation, transmission, distribution, utilisation and protection. Supplied with a comprehensive user guide which includes equipment descriptions, theory and experiments. Also, the open and flexible structure of the equipment makes it ideal for student projects and for lecturers to create their own experiments
