Answer Posted / hazem el-henawy
Harmonics are integral multiples of some fundamental
frequency ,if the fundamental frequency is f, the harmonics
have frequencies 2f, 3f, 4f, . . . etc., when added
together, result in a distorted waveform, It generates due
to improper switching action, they disturbance the Grid and
equipments.
filters generates Harmonics of opposite polarity to system
Harmonics to nullify the effects,We use filters to get a
stable system.

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.
