Scope

This part of GB/Z 23756 is a guidance document on the principles and procedures of electrical resistance evaluation tests for insulation systems, and also provides recommendations for developing electrical resistance methods and tests.
In this part, the background information on electrical resistance tests for insulation systems is explained, and test procedures are recommended when electricity is the main aging factor. At the same time, methods for statistical processing of electrical aging data using a normal distribution are also recommended.
The appendix of this part is an informative appendix, which includes other statistical distributions of electrical resistance test data for insulation systems.
