| Abstract: | In terms of the basic parameters and configuration characteristics of tank type shunt capacitors which are composed of a number of larger elements,this paper educes the calculating formulas for their differential voltage protection and over-voltage times on intact elements after any element is in failure,as well as gives an example for protection calculating and explaining,then discusses some factors that affect initial imbalance voltage. |
