  ABSTRACT: The ultra high frequency (UHF) electromagnetic wave detection method has been widely studied and used in partial discharge (PD) measurement and as a diagnostic technique for insulation performance in gas-insulated switchgears (GIS) and transformers. The UHF method has advantages such as high sensitivity, wide detection range and reduced external disturbances. On the other hand, there are still some issues to be solved in the UHF methods, such as a clear understanding of the propagation characteristics of electromagnetic waves arising from the structure of the equipment, optimization of antenna design, calibration of charge, etc. This article deals with the present status and future trend of the technology of this promising UHF method of PD measurement, together with recent activities and results from our laboratory.

  ABSTRACT: This paper deals with partial discharge measurement on three phase construction. It was shown that the measurement must be conducted on all phases simultaneously to obtain measurement result of partial discharge occurring in whole region of three phase construction with high sensitivity and to obtain information of the partial discharge location. Partial discharge from artificial defect was measured. Experimental results showed some special characteristics of partial discharge in three phase construction. These results were discussed with considering electric field characteristic in three phase construction and coupling capacitance between three phase conductors and between the conductors and the tank
