we have 3 phase 4 wire supply 230/415 V.AC and our distribution is single phas

we have 3 phase 4 wire supply 230/415 V.AC and our
distribution is single phase or we have all single phase
220 v,ac operated appliances. and noted the current with
help of clamp meter Red to N = 20 Amps. Yellow to N = 45Amps
and Blue to N = 30 Amps ( total is 95 Amps ) what will be
neutral current on the main .

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.
