Answer Posted / tharanidharan a
1.1 is form factor of a Sine wave...hence ac voltage being
a sine wave holds Form Factor of 1.1, which
is the ratio of rms value to average value of alternating
current.so generation of ac voltage is in multiple of 11,
like 11kv,33kv,44kv,66kv etc

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.
