This type 2 IEC technical report applies to insulator sets comprising string insulator units of ceramic material, glass or composite material for use on a.c. overhead lines and traction lines with a nominal voltage above 1 000 V and a frequency betvveen 15 Hz and 100 Hz.
This technical report also applies to insulator sets of similar design used in substations.
This technical report establishes a standard test procedure for power are tests on insulator sets.
This technical report does not apply to insulator sets mounted on non-metallic poles or tovvers.
The object of this technical report is:
- to define the terms used;
- to prescribe a standard test procedure;
- to prescribe criteria to evaluate the results of the tests.
