What is BS EN 50152-3-2 - Current transformers used in A.C. traction system for railways about?
BS EN 50152 discusses the particular requirements for A.C. switchgear for railways. BS EN 50152-3-2 provides the best industry guidance for the current transformers used in A.C. traction systems to enhance the safety and performance of the current transformers.
BS EN 50152-3-2 is the second subpart of the third part of a multi-part series that applies to new current transformers that are:
- Intended for use in indoor or outdoor fixed installations in tractions systems
- Operated with an A.C. line voltage and frequency as specified in EN 50163 Current transformers are mainly used with:
- Measuring instruments
- Protective devices
BS EN 50152-3-2:2016 also applies to current transformers other than inductive types as far as reasonably possible. Requirements of this BS EN 50152-3-2:2016 have priority.
Note 1: EN 50163 specifies the A.C. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz.
Note 2: As rails of A.C. traction systems are typically connected to the earth and included in the return current path, all phase-to-earth voltages are subject to the limits as given in EN 50163. Nevertheless, conductor to conductor voltages is sometimes higher e.g., in autotransformer systems.
Note 3: Combined current and voltage transformers also capacitive voltage transformers are typically not used in fixed installations in traction systems.
Who is BS EN 50152-3-2 - Current transformers used in A.C. traction system for railways for?
BS EN 50152-3-2 on the current transformers used in A.C. traction systems for railways is useful for:
- C. switchgear manufacturers
- Test centers
- Personnel or staff in charge of A.C. traction systems
- Regulatory authorities
Why should you use BS EN 50152-3-2 - Current transformers used in A.C. traction system for railways?
In an electric power system, A.C. switchgear is composed of electrical disconnected switches, fuse, or circuit breakers used to control, protect, and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow it to be done and to clear faults downstream.
A current transformer is a device used to produce an alternating current in its secondary, which is proportional to the AC in its primary. This is primarily when used when a current or voltage is too high to measure directly.
BS EN 50152-3-2 guideline assists you with nominal voltage, rated voltage, insulation coordination, rated insulation level, rated frequency, rated accuracy class, standard values of rated voltage factor, standard values of rated voltages, and Ferro resonance for current transformers for specific use in A.C. traction systems.
BS EN 50152-3-2 also guides on design, construction, tests, safety, the influence of the product on the environment, rules for transport, storage, erection, operation, and maintenance for current transformers for specific use in A.C. traction systems.
With compliance and obedience to BS EN 50152-3-2, you can standardize the safety measure and performance of current transformers for specific use in A.C. traction systems used in railways.
