What is BS EN 50152-2 - Disconnectors, earthing switches, and switches with a nominal voltage above 1kV about?
BS EN 50152 is a European standard that discusses requirements for alternating current switchgear for railways. BS EN 50152-2 is the second part of a multi-part series that applies to single-pole and two-pole alternating current (A.C.) disconnectors, earthing switches to minimize the hazards while operating.
BS EN 50152-2 covers switches that are:
- Designed for indoor or outdoor fixed installations in tractions systems
- Operated with an A.C. line voltage and frequency as specified in EN 50163
Note 1: As rails of A.C. traction systems are connected to the earth and included in the return current path all phase-to-earth voltages will be within the tolerances as specified in EN 50163. Nevertheless, phase to phase voltages is sometimes higher, e.g., in autotransformer systems.
Note 2: Under BS EN 50152-2 the two poles of a switch can be connected in series to provide secure isolation (i.e., two breaks in series).
Who is BS EN 50152-2 - Disconnectors, earthing switches, and switches with a nominal voltage above 1kV for?
BS EN 50152-2 on disconnectors, earthing switches, and switches with a nominal voltage above 1kV is useful for:
- Manufacturers of disconnectors, earthing switches, and switches with a nominal voltage above 1kV
- Test centres
- Regulatory authorities
Why should you use BS EN 50152-2 - Disconnectors, earthing switches, and switches with a nominal voltage above 1kV?
Switching device is a general term covering disconnectors, earthing switches and switches. A single-pole switching device with one electrically separated conducting path for the main circuit is suitable for use in a single-phase circuit.
BS EN 50152-2 guideline assists you with normal service conditions, special service conditions, rating, design, construction, type tests, dielectric tests, electromagnetic compatibility tests, making tests, breaking tests, operating endurance test, mechanical endurance test, and routine tests for disconnectors, earthing switches, and switches with a nominal voltage above 1kV for alternating current switchgear.
BS EN 50152-2 guides on the selection of switching devices for service, information to be given with inquiries, tenders, and orders for disconnectors, earthing switches, and switches with a nominal voltage above 1kV for alternating current switchgear.
BS EN 50152-2 also guides on the safety, the influence of the product on the environment, rules for transport, storage, erection, operation, and maintenance for disconnectors, earthing switches, and switches with a nominal voltage above 1kV for alternating current switchgear.
With obedience and compliance to BS EN 50152-2, you can standardise the quality of disconnectors, earthing switches, and switches with a nominal voltage above 1kV for alternating current switchgear. In addition, minimise the hazards of alternating current switchgear while operating.
