What is BS EN 50152-3-3 – Requirements for Voltage transformers for specific use in A.C. traction systems about?
BS EN 50152 discusses requirements for a.c. switchgear for railways applications. BS EN 50152-3-3 provides for voltage transformers for specific use in A.C. traction systems to standardize the safety measure and performance of voltage transformers in a.c. traction systems.
BS EN 50152-3-3 is the third subpart of the third part of a multi-part series that applies to new voltage 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
BS EN 50152-3-3:2016 also applies to voltage transformers other than inductive types as far as reasonably possible. Requirements of this BS EN 50152-3-3:2016 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 50152-3-3 - Requirements for Voltage transformers for specific use in A.C. traction systems for?
BS EN 50152-3-3 on the requirements for Voltage transformers for specific use in A.C. traction systems is useful for:
- A.C. switchgear manufacturers
- Voltage transformers manufacturers
- Test centers
- Personnel or staff in charge of A.C. traction systems
- Regulatory authorities
Why should you use BS EN 50152-3-3 - Requirements for Voltage transformers for specific use in A.C. traction systems?
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.
BS EN 50152-3-3 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 Voltage transformers for specific use in A.C. traction systems.
BS EN 50152-3-3 also guides design, construction, tests, safety, the influence of the product on the environment, rules for transport, storage, erection, operation, and maintenance for voltage transformers for specific use in a.c. traction systems.
With compliance and obedience of BS EN 50152-3-3, you can standardize the safety measure and performance of voltage transformers for specific use in a.c. traction systems used in railways.
