Abstract
This report deals with A.C. measurements of H.V. insulating arrangements on site and in laboratory. The inspection of H.V. insulation of electrical equipment is first of all to recognize defects of these insulations as early as to prevent breakdown of apparatus. The special difficulty of these inspection results form the large dimensions of this equipment. The PD- measurements consider the test-circuit transfer characteristic influenced by the large physical and geometrical dimensions, the individual conditions of the test objects and the disturbance levels found on several places. For state evaluations of electrical insulations different test arrangement and measuring devices are used. The report gives a comparison between such methods with regard to the impact on the PD-signal and its spectrum from the generation up to the evaluation.
