A lightning arrester is a self-quenching spark gap. When overvoltaged it arcs over, briefly shorting the power line to ground to prevent the voltage surge from reaching the equipment. When the overvoltage condition ends, the self-quenching mechanism activates to stop the arc removing the temporary power to ground short and restoring normal operation.
- Advantage: safety and prevents damage to expensive equipment.
Lightning arresters are placed on all power lines entering and leaving substations, power plants, and buildings at customer facilities.
Although somewhat similar in purpose to surge suppressors, they use different technology. Lightning arresters will only protect against surges of several thousand volts above the peak voltage on the power line, surge protectors protect against surges of about 50 volts above the peak voltage of the power line.

Why cannot the energy from lightning be Used?
I think that lightning is too fast to be conserved or converted and also lightning is unpredictable, so cannot afford to build lightning towers everywhere. That's why it cannot be used ,to stay safe from the effects of lightning it has to be earthen-ed BETTER SAFE, THAN SORRY
What is the adjective form of lightning?
The noun lightning itself (electrical discharge) is used as a noun adjunct, rather than an adjective, in such terms as lightning bolt or lightning rod. Only when the intent is to show great speed or quickness (lightning speed, lightning reflexes) is lightning an adjective.
What are the metals used for lightning conductor?
copper
What is the lightning between clouds?
Lightning is just really large static. Lightning between clouds is called cloud lightning or sheet lightning and is caused when one cloud has an excessive charge and another cloud has an excessive amount of the opposite cloud. The lightning is used to relieve the clouds charge.
Which of these words is used to describe a flash of lightning?
Bolt
What are the different types of relays used in substation?
kinds of electrical relays
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
What type of gas is used in a gas insulated substation?
sulphur hexa-fluouride
What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
Why the capacitive voltage transformer and voltage transformer both are used in a substation?
three phases
What grid substation?
this type of substation are considered important because any sort of disturbance in these substation may lead to the failure of grid.this type of substation are used to transmit huge amount of power from one point to other point in the gridAnswerA substation is a location where electricity transmission/distribution voltage-levels are changed and switching is carried out, as opposed to a power station, where electricity is generated. A substation, therefore, is a yard/building in which there are Transformers, switchgear, busbar systems, and protection systems.A grid substation is part of the electricity grid system -i.e. part of the transmission system. In the UK, this involves voltage levels of 400 kV, 275 kV, and 132 kV.

Why bus bar is rectangular?
Busbars are not necessarily rectangular. Those used in substation compounds are frequently tubular in construction.
Why used transformer in subststion?
The substation is there to convert a high voltage to a lower voltage for electricity supply. Transformers are needed to do this.
Can the word lightning be used in a sentence?
The lightning struck the top of the building.
What is the past tense of lightning?
Lightning can be used as a noun (bolt of lightning) or an adjective (lightning fast). It is not a verb, so it does not have a past tense form.
What is the Difference between air insulated substation and gas substation?
Air insulated means the substation is in the open air, and the dielectric strength of the air is used to isolate conductors from each other and from ground. Gas insulated means a specific gas is used for insulation; this gas is usually an inert gas such as nitrogen. Gas insulated substations, by definition, are required to be inside a contained structure, or large piping must be placed around all conductors to hold the gas.
