NONLINEAR OVERVOLTAGE LIMITER APPLICATION FOR INTERNAL OVER-VOLTAGE PROTECTION IN AVERAGE VOLTAGE NETWORKS

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2005
Review of internal over-voltages in distribution networks 6…10 kV and means of their limitation has been carried out. One of the most efficient remedy for reduction of over-voltage at arcing ground is resistive neutral grounding.

Measurement of velocity and diameter of tungsten particles produced by arcing using high-speed video

open access: yesNuclear Materials and Energy
Arcing is a mechanism of dust production and erosion in fusion devices. The masses and velocities of tungsten (W) particles produced by arcing is of special interest given that W is used as wall material in current experimental devices and is planned for
