Lightning Arrester

 

Lightning Arrester

 

A lightning arrester is protective devices to protect the equipment from lightning surge voltages due to lightning strikes while using it there won’t be any disruption of service because it will protect the equipment. It is also known as surge arrestors.

It is a device that is used in electrical power systems to protect the insulation on the system from the damaging effect of lightning, in earlier day metal oxide varistors are used for power system protection. a lightning arrester has a high voltage terminal and ground terminal

 

Lightning Arrester feature

 

What exactly does a Lightning arrester do?

 

1. It does not absorb the lightning

2. It won’t stop the lightning

3. It diverts the lightning to the ground

4. Arresters limit the voltage produced by the lightning

5. Lightning arresters equipment will be electrically in parallel with it

 

Lightning arrester work

 

Working of a Lightning arrester

 

In all the lightning arresters a Metal oxide varistor is used, the MOV is a semiconductor that is sensitive to voltage. At normal voltage, MOV disk is an insulator and will not conduct current, but in higher voltages which would be created by lightning or any surges it will become a conductor

The MOV disk will be placed in porcelain enclosure to provide physical support and heat removal and it will be sealed for isolation from contaminating in the electrical environment

 

While an electrical system is hit by a surge of electricity, it would seek to equalize and dissipate as quickly as possible and it will take the path of least resistance, and thus by using a resistor the electrical surge can be diverted from equipment insulation and then it will be channeled to the ground through grounding rods, so to do this the electric components uses a metal oxide protect circuits.

 

Types of lightning arrestors

 

Types of lightning arrestors

 

Station class

 

It is mostly used in an electrical power station or substations and other high voltage structures, this arrestor will protect against all types of overvoltages and lightning when the electrical devices have more current in the system lightning arrestors are designed that can be handled. It is used to protect the equipment which is above 20mVA range.

 

Intermediate class

 

It will also protect the equipment from electrical surges caused by the lightning and overvoltages it is designed to use in medium voltage equipment areas. The intermediate class is designed to use in the equipment which ranges from 1-22mVA

 

Distribution class

 

It is commonly used in transformers both dry type and liquid-filled. It is used in equipment that is rated at 1000KVA or less, it is used in exposed lines that have a direct connection to the rotating machines.
