"MOV is the main protection device of the capacitor bank. MOV operates as a voltage limiter by reduc- ing the voltage loading over the capacitor banks according to MOV ratings. When MOV protection operates the rise of energy causes the temperature to rise inside of it. Main rating principles are the amount of energy and the rise rate of the energy. These components also define the accuracy of the varistor."
