How do you install virtutools?
you right click and hit the install button
What does the lightning symbol on a laptop mean?
It Means Charging
How can you install a licensed program twice?
Install the program to a different location.
Can you safely remove old Microsoft updates from your computer?
Yes, if you would like to remove(un-install) a program you go onto the control panel and the go onto install, un-install a program then find the program you would like to un-install then click on it and un-install.
When is it appropriate to install pirated software on a computer?
it is never appropriate to install pirated software
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.
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.
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.
The location of lightning arrestor is?
lightning arrestors are placed at the incoming of the switch yard and also before the power transfofmer.
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
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
How can you stop water pipes from water hammer?
Install a water hammer arrestor (air chamber)
Can you protect buildings from being struck by lightning?
Yes, install a lightning rod.
What is an arrestor?
An arrestor is an alternative term for a buffer stop.
Would it be dangerous to install a lightning rod on a cloudy day?
Once there is a possibility of rain or thunderstorm you should not install it at that time. It would be safer for you to install the lightning rod on a sunny day.
How do you connect surge arrester?
The surge arrestor is clipped onto the rail in the DB next to the existing breakers, the live (red) wire is looped from the existing live loops above the other circuit breakers onto the top of the surge arrestor. The bottom of the arrestor is connected to the earth bar. It would be better to install a seperate earth spike and connect the botom of the arrestor to that to make sure that you have a good earth but it is sometimes not possible if the DB enclosure is indoors.
