SURGE VOLTAGE PROTECTION OF ELECTRIC PLANT IN OIL INDUSTRY
The article reveals the peculiar features of electric supply systems of oil producing enterprises, in which the surge voltage protection is provided by the nonlinear-resistance arrester. The article gives the data on internal overvoltage and insulation level in the network of 6 - 35 kilovolt. And the efficiency of nonlinear-resistance arrester substitution with the surge arresters is shown.
