IN 6.6KV 3 phase switch gear .i will give 6.6kv to R phase
only to earth in during H.v testing (through H.v KIT).what
happen remaining phases.how much voltage get remaining
phases.why? explain.
Any website for objective type questions of electrical engineering ?
We all have seen transmission and Distribution lines In transmission lines the voltage is high and current is low(to reduce I^2r loss) and in distribution lines voltage is low but current is high however the size of transmission wires is bigger than that of distribution wires even though the amount of current carried by the distribution lines is more than that of transmission lines why?
