why 3phase is 440v but where as we get phase voltage 220v,we
have to get 220*3=660v.can u pleas give in detailed
Answer Posted / shahulsnfa
Basically phase to phase voltage gives 440 and phase to
neutral gives 220. we can get 440 even with two phase. It
doesn't mean three phase supply should be 660. Reliablity
is more if we have three phase instead of two phase.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
