Q34. What is earthing and why is it necessary?
Ans : Earthing or Grounding an object/tower means providing an electrical connection
between that object/tower and mother earth. This electric connection is achieved
by running an electrical wire/strip between the tower and an earth
electrode. Earth electrode is a metal plate/pipe/sphere properly embedded at a
depth in the earth. This Earthing/Grounding of tower is necessary to :
a) Prevent damages to delicate instruments or humans due to stray voltages/currents
b) For optimum performance of the communication system.
