Resumen (inglés):
IEC 61857-32:2019 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.
