Answer Posted / jay prakash
a wawe trap is the device which trap the high frequency
signals to enter into substation.
As XL =2 Pi w f L as impedence is directly proprtional to
frequency thus provide high impedane for high frequency
(carrier frequency)& vice versa.
lightning arrester prevent the substation from lightning
impulse, under normal condion impedace of air gap is high
enough for the voltage i.e no discharge, in case of
lightning high voltage appears around air gap and cause a
discharge through air and go to ground and prevent from
fault
