WebJan 13, 2024 · 2) The voltage across the nearest disc to the conductor is maximum than others disc. 3) The unit nearest to the conductor is under maximum electrical stress and is likely to be punctured. 4) In the case of D.C voltage, the voltage across each unit would be the same. It is because insulator capacitance are ineffective for D.C. Calculation: WebPorcelain disc insulators are typically used in power transmission line. Porcelain is the most commonly used insulating material until now. Not only any voltage but also any contamination level can be done by changing …
WebThere are two types of construction in disc insulators (1) Cemented cap type and (2) Hewlett or interlinking type With a pin insulator the conductor is connected to the insulator and is above the crossarm. In case of suspension insulators, the conductor is below the crossarm connected and suspended from the disc insulator.
