One lightning arrestor covers how much area?
Lightning arrestor or lightnng ROD? An arrestor typically covers a given electrical circuit- lightning rods cover outside area. Area will depend on the heighth of the rod above lower surfaces.
Why lightning arrestor should be placed near transformer?
A lightning arrestor acts to reduce a voltage surge due to, for example, a lightning strike on a power line. This will protect the transformer from an over-voltage acting to break down its resistance. A lightning arrestor is connected between each line conductor and earth. Under normal voltage conditions, it acts as an insulator, but when a critical value of over-voltage is reached, it conducts -suppressing the voltage spike.
Why the rating of lightning arrestor is less than its rated voltage eg for 400 kv system it is 360?
The MAXIMUM rated voltage is the voltage at which the electricity would arc across the insulators The usage voltage is lower than the rated voltage (usually somewhere around 80% The lightning arrestor voltage is in between. It will not pass current at the usage voltage, but will pass current when the voltage exceeds the arrestor threshhold
Can lightning be blue and round?
they can be blue but not round they are like tress with branches on them striking down on a location
What is a required to have a backfire flame arrestor?
a boat with a gasoline inboard engine

How do you install a lightning arrestor?
by action of points
How does a lightning arrester works?
Actually when there is lightning it directly falls on lightning arr-ester and this lightning arr-ester is connected with ground wire so that it could not damaged the rest system.AnswerA lightning arrestor is a protective device used to protect high voltage power lines against lightning strikes. The upper end of the lightning arrestor is connected to a line conductor, and the lower end is connected to earth. For normal operating voltages, the lightning arrestor acts as an insulator, but when a particular voltage is reached due to a lightning strike, the device conducts, providing a path to earth.

What is Lightning arrestor?
A device, composed of sharp points and/or knife edges, that discharges powerline overvoltages to ground. The term lightning arrestor is a misnomer, as these devices cannot protect against a direct strike to the powerline!
What does LA mean in 3 phase power systems?
LA is short form for Lightning Arrestor

What is an arrestor?
An arrestor is an alternative term for a buffer stop.
How can you protect the lighting arreseter from damaged?
The question is ambiguous. You can pack it carefully for transport if that is what you're wanting to know. Lightning arresters fail at times. I don't know that there is anything you can do to prevent this. I believe the normal procedure is to check the drainage current flow on a regular basis, and if this is increasing to unacceptable levels, replace the arrestor. It may be possible to refurbish an arrestor, but I have never seen this done.
What is meant by lightning resistor?
More properly Lightning arrestor, not resistor, which would be a circuit component. this is a safety device required by electrical codes(which amount to laws) to be used on all radio transmitter stations but particularly ham stations. the device protects the equipment from lightning strikes and damage. This is an external component that only works when needed like a safety valve on a boiler to relieve pressure.
Is it ok to remove the spark arrestor?
No.
What is the use of surge arrestor in the telecommunication power supply system?
The same as any surge arrestor equipment - to prevent surges from damaging the (telecom) equipment.
