Why are the voltage levels in a powersystem are 11KV,33KV
etc., why not 10KV,30KV?
Answer Posted / s.rajkumar
In general the voltages are represented in RMS values which
is obtained by multiplying average value with form
factor..........in general voltages are taken in terms of
average values as you have said (10,20......) but as we
multiply it with form factor which is 1.11 for sinusoidal
waveform the voltages become 11Kv,21Kv,33Kv,66Kv...........

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.
