WebMETHODS OF IMPROVING STRING EFFICIENCY. It has been seen above that potential distribution in a string of suspension insulators is not uniform. The maximum voltage appears across the insulator nearest to the line conductor and decreases progressively as the cross arm is approached. If the insulation of the highest stressed insulator breaks … WebSep 9, 2024 · String Efficiency is defined as the ration of conductor voltage and the voltage across the disc nearest to conductor multiplied by number of discs. String Efficiency = …
WebFeb 19, 2016 · 2 Answers Sorted by: 1 Guard ring increases the string efficiency of an insulator string practically. If we don't use the guard wire then the voltage across different insulator disks will reduce as we move away from the conductor, thus the highest voltage will appear across the insulator disk which is nearest to the conductor.
WebIn a 33 kV overhead line, there are three units in the string of insulators. If the capacitance between each insulator pin and earth is 11% of self-capacitance of each insulator, find (i) the distribution of voltage over 3 insulators and (ii) string efficiency. Solution The equivalent circuit of string insulators is, WebJun 10, 2024 · I have designed how to measure the voltages across each insulator disc and measure the string efficiency. Following main objectives have been designed in the matlab/Simulink. 1. String Efficiency Model without the Effect of Shunt Capacitance. 2. String Efficiency Model including the Effect of Shunt Capacitance. 3.
