A: In the sky there is potential caused by friction of particles. This is a potential to release the charge if a path is found to discharge like earth or another cloud At that time current can flow Millions of amperes will be discharged to earth for that split instance a building can rise to 1000 of volts with respect to earth ground What it means is that the POWER grid can see a rise or rather a spike on its lines which will reflect all the local distribution as surge of power.

What is a surge in voltage or current in an electrical circuit called?
A transient, surge, spike, etc.
What is surge current and surge current rating?
Electric motors typically have a surge (Also called in-rush or start up) current rating. When the motor is not energized it takes added power to start it rotating. This is just like when you step on the accelerator pedal to get your car moving and then ease off on the gas pedal when you get at speed. One rule of thumb is that the surge current may be as much as 6 times the running current.
What is the difference between an electrical surge and a brownout?
A surge is an over voltage and over current situation and a brownout is an under voltage situation.
Can TVs diode can be connected in series to increase the surge current?
No. By Kirchoff's Current Law, components in series all see the same current.
How surge current is produced in a capacitor input filter?
Being that the capacitor appears as a short during the initial charging, the current through the diodes can momentarily be quite high. To reduce risk of damaging the diodes, a surge current limiting resistor is placed in series with the filter and load.
When lightning hits a lightning rod does it create spark or fire?
No, the current simply travels through the rod and spreads into the earth.
How do you protect your computer from lightning?
A surge protector.
How do you make Home Insurance Claim for damage to electrical appliances from a power surge?
A lightning strike has very much the same effect on electrical appliances as a power surge. An electrician will not easily tell the damage from these two events apart. Insurance covers for lightning, not for a power surge. So in short, claim for lightning damage, not power surge damage.
Do surge suppressors protect the computer from a lightning strike?
yes
What is MCOV rating for lightning arrester?
It is Maximum Continuously Operated Voltage to select the rating of Surge arrester or lightning arrester.
How does lightning realate to electricity?
Well i don't know about electricity but i know about static electricity. Lightning is like static electricity, except on a much bigger scale. Both lightning and static electricity happen because of the attraction between the opposite charges. When static electricity moves, it is a current. When static electricity in clouds discharges to earth there is a huge, very short current pulse (surge).
Should a HV substation be able to handle a direct positive lightning strike with no damage?
In Principe - yes, because surge amplitude is smaller then negative lightning strike surge and it is only one stroke by discharging.
What type of lightning protection equipment do I need for my house I just purchases in Evansville, Indiana?
There are many types of lightning protection equipments such as grounding units, surge suppressors, and conductors. If you have electronic equipments, definitely get surge protectors.
What is a surge in voltage or current in an electrical circuit called?
A transient, surge, spike, etc.
What should they buy to protect their computer during future lightning storms power surge circuit board ground wiresurge protector?
A surge protector
What is surge socket?
Provides protection during mains power surges and lightning strikes.
