Description of BS EN IEC 61857-32:2019 2019

This part of the 61857 series is focused 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. Clear guidelines are needed to give the user of this document a uniform approach and a method to analyse the test results.

This document 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.
