The need for testing at HVDC and UHVDC levels has increased dramatically over the last few years. Typically test objects include valves, cables, line insulators, cable accessories, optical instrument transformers and station post insulators. Some of

At present line and apparatus composite insulators are widely accepted for use on AC overhead lines and in high voltage substations. The present paper concentrates on measurements of different pollution parameters of naturally exposed apparatus compo

In laboratory set-ups, polymer covering of the electrodes has resulted in the reduction of the insulating distances by a factor two. One of the problems with covered conductors is however that of creeping discharges on the surface of the covering. Th

For an improved design of high voltage apparatus a material with a low dielectric constant and a relatively high breakdown strength is advantageous. Therefore the insulating properties of polymer foam with closed pores are investigated. It was found,

The behavior of partial discharges (PD) along a polymer foam insulator in air is investigated at 50 Hz AC voltage. The results were compared to the PD behavior along other solid/air interfaces. The PD inception voltage depends on the dielectric const

The application of high DC voltage to a polymer/air insulation system can result in space charges on the interface. The space charges can cause significant distortions of the electric field distribution, which may trigger a surface flashover or break

The breakdown development of a covered rod/plane air-gap arrangement was investigated under lightning impulse stress. At positive polarity of the rod a flashover along the cover surface is followed by a breakdown of the air-gap. At negative polarity
