Why A.C needs more insulation than D.C at same voltage level?

Question

Faseela Erayathara · Answer

potential stress on the insulation is less in DC than in AC system

tapas Sethi · Answer

For the same working voltage, the potential stress on the insulation is less than in case of DC system than that AC system. Therefore , a DC line requires less insulation. In other words A DC System has a less potential stress over AC system for same Voltage level and power rating, this is why AC needs more insulation than DC system.

JESSYL ALCAPARRAS · Answer

A.C needs more insulation than D.C because of potential stress on the insulation that is less in D.C than A.C system

Emad Atia · Answer

because of the potential stress on the insulation is less than in case of DC system than that AC system. Therefore , a DC line requires less insulation.
