What is BS EN 60034-18-21 – Thermal evaluation of wire-wound winding about?
BS EN 60034-18-21 is a European Standard on rotating electrical machines that provides test procedures for the thermal evaluation and classification of insulation systems used or proposed for use in wire-wound alternating current (a.c.) or direct current (d.c.) rotating electrical machines.
The test performance of a candidate insulation system is compared to the test performance of a reference insulation system with proven service experience.
Who is BS EN 60034-18-21- Thermal evaluation of wire-wound winding for?
BS EN 60034-18-21 on thermal evaluation of wire-wound winding is relevant to:
- Manufactures of rotating electrical machines such as stator end-winding
- Electrical design engineers
- Companies dealing with electrical systems
- Retailers and dealers of various rotating electrical machines
Why should you use BS EN 60034-18-21 - Thermal evaluation of wire-wound winding?
The rotating electrical machine consists of a stator, rotor, and air gap between them. Large AC machines are equipped with multiphase stator windings. The thermal endurance test procedure uses several cycles, each consisting of: a thermal aging sub-cycle, a diagnostic sub-cycle, which includes mechanical and moisture conditioning followed by a diagnostic voltage test and performed in that order.
BS EN 60034-18-21 provides you with standardized test procedures, test objects, test specimens, diagnostic sub-cycle, and a description of thermal ageing sub-cycle.
Overall BS EN 60034-18-21 helps demonstrate the test performance and diagnostic procedures for wire-wound windings, ensuring that they play a positive role in the operational efficiency of overall rotating electrical machines. With the help of BS EN 60034-18-21 best practice guidelines, you will be able to improve electrical insulation systems and produce safer electrical equipment.
