Abstract :
This work presents results of studies about protection 3-phas capacitor bank before very dangerous overvoltage and overcurrent generated by a vacuum switch. For the protection used to varistors in three possible combinations when the neutral point of capacitor bank is insulated The study compares presented methods and gives the answer which one is the best. All results comes from simulations in ATP/EMTP program.
