WebSep 25, 2011 · The value of string efficiency depends upon the value of K i.e., ratio of shunt capacitance to mutual capacitance. The lesser the value of K, the greater is the string efficiency and more uniform is the voltage distribution. The value of K can be decreased by reducing the shunt capacitance. WebThe string efficiency of suspension insulators can be derived using the following diagram. It consists of 3-disc string suspension insulators with a metallic link between them to provide a capacitive effect between them. The effect can be either self-capacitive or mutual capacitive. Let us assume shunt capacitance = k * self-capacitance.
