What is BS EN IEC 61857-32- Diagnostic testing for electrical insulation systems about?
BS EN IEC 61857-32 is an international standard on evaluation and qualification of electrical insulating materials and systems.
BS EN IEC 61857-32 is 32nd part of the IEC 61857 series that focuses on applications where other possible factors need to be incorporated to evaluate any influence on the performance of the electrical insulation system (EIS). Multi-factor evaluation is the most complex type of project to design and conduct.
BS EN IEC 61857-32 is for applications where the stresses are some combination of other factors of influence identified in IEC 60505. The multi-factor stresses are applied during the diagnostic portion of each test cycle. A few examples of other factors of influence or multi-factor stresses are:
- High vibration
- Submersion in oils, water, or solutions
- Voltage higher than the test voltage of the reference EIS
- Decreased cold shock temperature
Who is BS EN IEC 61857-32- Diagnostic testing for EIS for?
BS EN IEC 61857-32 on diagnostic testing of electrical insulation systems is relevant to:
- Electrical insulation system manufacturers
- Electrical industry
- Laboratories
- Electrical engineers
Why should you use BS EN IEC 61857-32 - Diagnostic testing for EIS?
An electrical insulation system is comprised of a unique combination of materials that have been verified for chemical compatibility when used at certain maximum temperatures. Accelerated ageing of an electrical insulation system is intended to evaluate the thermal classification of the EIS. Many applications need to include the evaluation of other factors in addition to the thermal factor related to the application.
BS EN IEC 61857-32 provides four categories of stresses or ageing factors which influence the performance of products in use under a wide range of operating conditions. They are Thermal [T], Electrical [E], Ambient [A], and Mechanical [M]. These increased factors during diagnostic testing can help establish the extent of resistance and durability of EISs.
BS EN IEC 61857-32 is useful as it enables protection of materials through which electric current flows. With BS EN IEC 61857-32-compliant testing, you can maintain over EIS integrity and operational efficiency.
