What is 'arrester' πŸ§‘β€πŸ”§

I decided to write about β€œWhat is 'arrester'” after a few colleagues asked for my help in the subject. If you are still in doubt, stick with me…

And the quick answer is…

A wire screen at the top of an incinerator or chimney which prevents sparks or burning material from leaving the stack.

The arrester provides a low-impedance path to ground for the current from a lightning strike or transient voltage and then restores to a normal operating conditions.

A surge arrester may be compared to a relief valve on a boiler or hot water heater.

It will release high pressure until a normal operating condition is reached.

In other words, lightning arrester diverts the abnormal high voltage to the ground without affecting the continuity of supply.

Arresters are typically installed near critical appliances or points of entry, such as an electrical panel or near a generator.

When potentially dangerous lightning strikes, the arrester activates and diverts the lightning to ground, where it will disperse harmlessly.

Note to self: Draft for a new post.
