What are five types of surge arrester?
There five types of surge arrester: 1. Rod gap arrester 2. Horn gap arrester 3. Protector tube or expulsion type 4. Thyrite lighting arrester 5. Gapless arrester or metal oxide arrester

Who invented lightning arrester?
Lightning arrester or lightning rod is a rod paired with a conductor. The lightning arrester was invented by Benjamin Franklin in the late 1749.
What is MCOV rating for lightning arrester?
The MCOV (Maximum Continuous Operating Voltage) rating for a lightning arrester is the maximum voltage that the arrester can continuously withstand without failing. It is important to select a lightning arrester with an appropriate MCOV rating to ensure that it can effectively protect against overvoltage events without being damaged.

Is thunder lightning arrester and thunder arrester same?
Yes, they are essentially the same thing. A lightning arrester is a device used to protect structures from damage caused by lightning strikes, which can also be referred to as a thunder arrester due to the loud noise produced by thunder during a lightning storm.
How do you change a lightning arrester to iridium?
To change a lightning arrester to iridium, you would need to replace the existing lightning arrester component with one made from iridium material. This may involve removing the old lightning arrester and installing a new one that is designed with iridium. It is crucial to ensure that the replacement arrester is compatible with the existing system and meets the necessary safety standards. Consulting a professional electrician or engineer for guidance is recommended.
What will you do if the surge arrester is damaged?
Replace it.
How can you rate surge arrester?
check NEC
How the voltage arrester works?
The voltage arrester works by conducting when there is enough voltage to turn it on. Often, an arrester on a primary distribution circuit has a spark gap to ground, so that lightning strikes are limited in voltage, protecting the circuit. Other types of arresters, such as MOV's, can be used in surge protectors.
Where be the surge arrester be placed?
Before the object on the positive and after on negetive
How does lighting arrester working?
A lightning arrester (or lightning rod) works by providing a low resistance path to earth. This directs a lightning strike down the side of a building instead of it spreading through the electrical system.
