In other words lightning arrester diverts the abnormals high voltage to the ground without affecting the continuity of supply. Lighting and voltage surge lightning can create voltage surges in several of the following ways.

What Is Valve Type Lightning Arrester Definition
Lighting arrester circuit diagram. The selection of arrester depends on the various factors like voltage current reliability etc. Lightning can score a direct hit on your house. The lightning arrester protects the electrical equipment from lightning. The value of α is 30 to 40 for zinc oxide blocks. A lightning arrester alternative spelling lightning arrestor also called lightning diverter is a device used on electric power systems and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightningthe typical lightning arrester has a high voltage terminal and a ground terminal. It is placed very near to the equipment and when the lightning occurs the arrester diverts the high voltage wave of lightning to the ground.
Lightning can strike branch circuitry wiring in the. It can strike the overhead power line which enters your house or a main power line that is blocks away from your home. When a lightning surge or switching surge which. The device which is used for the protection of the equipment at the substations against travelling waves such type of device is called lightning arrester or surge diverter. Hi friends in this article i am going to discuss about lightning arrester types and lightning arrester working principleyou will appreciate my effort i hope so. The v i characteristics of zinc oxide gapless zinc oxide lightning arrester can be represented with the following equation.
Where i and v are the reference current and reference voltage respectively. The lightning arresters are used to protect power system from high voltage surges. The function of the surge arrester is to allow the discharge of any dangerous over voltage before it can do damage and then to restore the line to.
