Electrical insulating materials used under severe ambient conditions - Test methods for evaluating resistance to tracking and erosion (IEC 60587:2022)
This document describes two test methods for the evaluation of electrical insulating materials
for use under severe ambient conditions at power frequencies (45 Hz to 65 Hz) by the
evaluation of the resistance to tracking and erosion, using a liquid contaminant and inclined
plane specimens. The two methods are:
– Method 1: test at constant voltage,
– Method 2: test at stepwise increased voltage.
Method 1 is the most widely used method as there is less need for continual inspection.
The test conditions are designed to accelerate the production of the effects, but do not
reproduce all the conditions encountered in service.
