Abstract

In acceptance testing of dry type, resin insulated instruments (voltage) transformers different partial discharges characteristics may be obtained by adopting the two arrangements suggested in the IEC 44-4 standard. Although the electric field distribution inside the component does not significantly depend on test arrangement, different partial discharge results are obtained. The unlike behaviours obtained by adopting the two set-ups are presented and explained. Some criticism to the present form of the standard is raised and suggestions of improvement are presented
