| Abstract: | By calculation of over-voltage and over-current produced by capacitor and reactor while the parallel capacitor compensation device is being input, analyzes the causes of burning of reactor, proposes to increase the insulation level of the windings of reactor and the whole device to earth and adopt the method of paralleling a 10 kV zinc oxide surge arrestor between reactor and capacitor in order to limit the over-voltage produced during operation of parallel capacitor compensation device. |
