Answer Posted / manish
Direct On Line( DOL) starter takeS Full load current
Ist=Ifl But STAR/DELTA starter which during starting of
motor , connected terminals with STAR which limits Ist
=Ifl/1.732*Ifl. Thus starting current can keep with in
limit.

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.
