Scope

This Part of GB/T 22719 specifies the interturn insulation test of random-wound winding for
AC electrical machines - test parameters, test limits and the allowable value of the test
waveforms difference quantity when doing the automatic test discrimination.
This Part applies to random-wound winding interturn insulation test for the 3-phase or single-
phase AC electrical machines of which the nominal voltage is no more than 1140V.
