Studying and Testing
A lightning arrestor or a surge diverter is a protective device which conducts the high
voltage surges on the power system to the ground.
Surge protection has been a primary concern when connecting devices and
equipment to low-, medium-, or high-voltage electrical systems. As the use of products and
equipment with components and insulation systems vulnerable to voltage surges and spikes
continues to increase, the requirement for surge arresters to protect against the effects due
to lightning strikes, switching phenomenon, etc., continues to increase as well. From
personal computers to HV transmission and distribution systems, everything is susceptible
to these surges and their destructive effects.
