State the difference between Surge Arrester and Lightning
arrester,Both are same or not?

Answer Posted / priyanka dhar

Lightning arresters are installed inside the distribution
board and they protect against surge volatges in case of
direct lightning strikes.

surge arresters are installed in sub-distribution board as
well as in terminal equipment thus protecting against surge
voltages due to distant lightning and due to internal
switching operations respectively.
