what is a lightning arrester???
Answers were Sorted based on User's Feedback
Answer / infodoss
lightning flow is mainly low resistance side(i.e
TREE,CRANE,SUPPLY LINE).so only lightning arrester made
with low resistances.It is the main reson to observe the
lightnings.it Always fix the top of manual
operating.lightning arrester used to protects the
electrical equipment.
