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.

What color should a H2 Conductor on 480 volt transformer should be marked?
The conductor for H2 connection on a 480 volt wire transformer should be marked:
What should you do after you get struck by lightning?
Go to a hospital.
Can a 1500KVA transformer feed a 1600A 480V service?
No, a 1500KVA transformer is not large enough to handle a 1600A load at 480V. The transformer should have a higher kVA rating to support the current demand of 1600A. A transformer with a minimum capacity of 1920KVA would be needed for this application.
Why should you never seek the shelter of a tree if you get caught out in a thunderstrom?
Trees attract lightning. They are tall. They are in the ground, which lightning seeks.
How did lightning rod improve people lives?
The lightning rod (USA), lightning conductor (UK) is a metal rod that is placed on the top of tall buildings. A metal cable or strap connects the conductor to another metal rod sunk deep into the earth. The principle is that should lightning strike the building, it is attracted to the conductor and travels down the cable to be dissipated safely into the earth - so saving the building from lightning damage. Wooden building used to burn down under stikes from lightening. The lighten rod (Ben Franklin) gives the electricity a easy path to the ground instead of a heat-producing path through wood.
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
Why Disconnect switch should be placed before current transformer cabinet?
Usually disconnects are placed around any equipment that you may have to do maintenance on in the future and don't want to have to take larger outages than necessary. If the current transformer is on a substation bus, and you don't want to take an outage to that bus, but would like to take a look at the CT's, you should put disconnects around it to allow such maintenance activities.
Should you be on your MacBook when in storm?
If it's a lightning storm, Your laptop is powered by an inline transformer as part of the power cord so, in theory,if lightning hits your house it will destroy the transformer first before hitting your laptop.At the very least, in theory, if you lose power in any storm, a power surge from the power being turned back on hits your transformer and destroys it first and not get as far as the laptop.Either way you can't be hurt from a storm just by using your laptop if your NOT connected to the power cord if your in your house or building.
Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
Can you use transformer with your 110 aircon?
A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.
Can i replace a dc 9 v transformer 200 mA for a 500 mA?
Yes. Yes, you can replace a transformer with one that has a higher current rating. The load on the transformer should be less than 200mA because presumably that is what the circuit was designed for. Since the current through the transformer should be less than 200mA, the 500mA transformer will not be damaged. The opposite is not true. You should not replace a 200mA rated transformer with a 100mA transformer, for example. If the current exceeds 100mA, the transformer could fry.
How do you diagnose if a transformer?
You should measure the
When operating a no load tap changer on a transformer what should be done first?
First isolate the transformer
What color should a H2 Conductor on 480 volt transformer should be marked?
The conductor for H2 connection on a 480 volt wire transformer should be marked:
Where should I install a water hammer arrestor in my plumbing system?
Install a water hammer arrestor near the source of the problem, typically near the shut-off valve or at the highest point in the plumbing system. This will help absorb the shock waves and prevent noisy pipes.
Does transformer works on DC?
I should think not
What happen if the number of loops in the primary and secondary coils in a transformer are the same?
If the number of turns in the primary is the same as the secondary, this would be an isolation transformer. Primary and secondary voltages should match (minus the inherent transformer losses), as should the current.
