In order to investigate the long-term behavior of contact resistance in low-voltage contactors under the influence of electric arcs in polymer housings, a new model switch was developed. The model switch permits the modification of different factors

The aim of this paper is to present a further approach for analyzing the air electric arc in low-voltage circuit breakers (LVCBs). In order to achieve that, a new simulation model and experimental tests have been carried out. The simulation model has

The use of renewable energy is a key topic in the global energy market. Wind parks are being built all over the world, especially offshore, and large hydroelectric power stations are producing enormous amounts of electrical energy. Yet, the regions a

In the field of HVDC bushings, temperature gradients inside the bushing core have more impact on the electric field distribution compared to AC. Furthermore, more experiences are existing in the DC case for the oil-insulation system than for solid-ga

Sulphur hexafluoride (SF 6 ) is the most common insulation gas in high voltage technology because of the electron attachment (electron affinity) SF 6 has a three times higher dielectric strength at 0.1 MPa compared to air. Beside this SF 6 has the mo

Due to a series of advantages the high voltage direct current (HVDC) transmission system is nowadays a standard technology in the fields of renewable energy, underwater or bulk power transmission or for stabilizing the high voltage alternating curren

Contrary to other test setups, a virtually unmodified contactor actuator has been integrated into a model switch to reproduce contact bouncing of make operations. This allows for a less complex machine than an electro mechanical or pneumatic replica

This paper reports a comparison between two different methods used for the synthesis of amorphous Si/C/N pre-ceramics: the laser pyrolysis method, coupled with an aerosol generator, and thermolysis in a furnace in an inert gas atmosphere. The same pr
