20、ds for the evaluation of electrical insulating materials for use under severe ambient conditions at power frequencies (45 Hz to 65 Hz) by measurement of the resistance to tracking and erosion, using a liquid contaminant and inclined plane specimens. The two methods are as follows: Method 1: constant
21、 tracking voltage; Method 2: stepwise tracking voltage. NOTE 1 Method 1 is the most widely used method as there is less need for continual inspection. NOTE 2 The test conditions are designed to accelerate the production of the effects, but do not reproduce all the conditions encountered in service.
22、2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 track partially conducting path created by localized deterioration on the surface of an insulating material 2.2 tracking progressive degradation of the surface of a solid insulating material by
23、local discharges to form conducting or partially conducting paths NOTE Tracking usually occurs due to surface contamination.
