Product Description

#4. Multiple-Gap Arrester:

Multiple-Gap Arrester

 

Arresters of this type are designed to be small metal cylinders in series. Which are separated from each other by means of air and are insulated from each other.

 

Whose first cylinder is connected to the line and the last and its next cylinder in series connected to the earthing. The intermediate cylinder has a shunt barrier at some intervals. The distance between the cylinders depends on the voltage of the line.

 

#5. Electrolytic Arrester:

Arresters of this type have a large discharge capacity only. It works in such a way that a thin strip of aluminum hydroxide is deposited on the electrolyte completely immersed on the aluminum plates. The plate acts as high resistance to low cost but fixed value. Less resistance to voltages than. Puncture at a voltage of more than 400 volts and causes the free flow of current to the earth.

 

When the voltage remains at its normal value of 440 volts, the arrester again provides high resistance in the path and stops the leakage.

 

#6. Expulsion Type Lightning Arrester:

Arresters of this type have an improvement in the distance of the rod in which it shuts off the frequency of power. This air raster uses a tube made of fiber which is very effective, separating the spark gap and the interrupted spark gap inside the fiber tube.

 

Expulsion Type Lightning Arrester

 

The spark of impulse inside the fibrous tube during operation destabilizes some of the fibrous material of the arc tube in the form of gas, which is called a vent from the bottom of the tube. Thus, extinguishing the arc is just like circuit breakers.

 

#7. Auto valve Arrester:

This type of arrester consists of several flat discs of mesh material that are mounted on top of one and separated by thin mica rings. Disk content is not homogeneous and admin content has also been added. So the glow discharge occurs in the capillaries of the material and the voltage drops to about 350 volts per unit. The disk is configured in such a way that normal voltage does not cause discharge.

 

 

 

#8. Valve Type Lightning Arresters:

This type of arrester applies to electrical systems that are more powerful. These devices consist of two main parts, the sequence of spark gaps as well as the series of non-linear resistor disks. These devices can operate whenever a high voltage spark strikes the gusset and the non-linear resistors have a grounding voltage. Whenever the surplus power surge stops, the spark gaps can be pushed apart by the resistors.

 

Advantages of Lightning Arrester:

The benefits of Lightning Arrester are as follows:

 

Damage caused by lightning can be minimized.

Easy to use.

Provides protection of equipment outside the substation.

Damage to the overhead line can be avoided.

Outlet surgeries can be avoided.

Electromagnetic interference.

Disadvantages of Lightning Arrester:

The Disadvantages of Lightning Arrester are as follows:

 

Prevents excessive space in the line.

Installation costs are higher.
