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.
