The operators working on electrical installations of low, medium and high voltages can be accidentally exposed to short-circuit arcs ranging from a few kA to several tens of kA. To protect them from radiation, according to the exposure limits, we nee

During live working at high and very voltage, it may be necessary to connect or disconnect parts of the network, but also large conducting parts. To carry out these operations, it is necessary to control: - values of current passing to the place wher

Breakdown sequence in SF6 of an electrode arrangement which represents the contacts of a circuit-breaker is investigated at pressures up to 8 bar under positive impulse voltages. The Schlieren frames point out the role played by the cathode as a sour

When no protection is used, the radiation emitted by a high-power electric arc can be dangerous for the eyes and the skin of a person. To ensure effective protection, it is first necessary to know the energy emitted by such arcs. The aim of our work

Experimental results of the development of a negative discharge in a 16.7 m rod-plane air gap are presented. Similarities with the cloud-to-earth discharge are found and some characteristic parameters are compared. Use of an image converter linked to

The impulse breakdown of 20 mm rod-plane gaps in SF6 has been investigated using impulse wavefronts in the range 10 ns to 10 mu s. The SF6 pressure is varied between 1 and 5 bar and results have been obtained with non-irradiated and gamma irradiated

Compounds for high voltage insulators are mixtures of rubber, fillers and additives. Polymers are generally either silicone rubber or EPDM and the filler is mostly alumina tri-hydrate (ATH). In this work, we focused on permanent changes of the surfac

Proceedings of 1995 Conference on Electrical Insulation and Dielectric Phenomena.
Polymeric housings for high voltage insulators are usually made with compounds of rubbers (silicone and EPDM) filled with alumina tri-hydrate. In order to test these materials, a 5000 hours multistress aging test was achieved together with a two year

A high-current pulsed arc struck between a 100-mm electrode gap in open air was experimentally studied by time-resolved imaging. The arc was created by a discharge current with an amplitude of 10 kA and a duration of about 10 ms. A high-speed camera

This paper deals with the electrode erosion because roughness produced by high current is one of the most important factors affecting dielectric performance in spark gaps. The large reduction of the threshold for breakdown in compressed SF 6 is studi
