As we know,charged clouds(from which lightning stroke initiates)may be charged with either +ve charge or -ve charge. Now say one cluster of cloude is fully charged with +ve charge & another cluster is fully charged with -ve charge. In the sky these two cluster of charged clouds have come in such a distance that, if they come clouser by some few yeards then the lightning discharge will take place between these two cluster of clouds. Under such a situation an Aircraft came inbetween. what happend??

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.
