THE ANSWER IS SHOWN BELOW.

Step-by-step explanation

1.

 

  • Lightning arrestor is a conductive device that permits lightning to ground quickly with the assistance of low resistance earthing. it's the power to ground the potential charges which occur during lightning.

 

  • Lightning arresters are typically installed near a critical entry point or appliance, including generators and electrical panels. 

 

  • When a bolt of lightning strikes, the arrester activates and deflects the lightning to the ground, where it disperses harmlessly.

 

2.

 

  • A Lightning protection system helps for preventing property damage from the consequences of a lightning strike.

 

  •  It helps to provide a way for controlling and preventing damages by providing a safe resistance path for the discharge of lightning energy.

 

  • When lightning strikes any building directly, it damages the structure of the building. Lightning needs a simple path to discharge when current is interrupted because of the high resistance path it discharges to the weakest point of the building structure. So as to avoid damages, we install lightning protection devices like lightning arrestors.

 

3.

 

a.Electrolytic Arrester

 

  • It has a high discharge capacity. 

 

  • It operates on the basic principles of an electrolytic cell. Expressly, here aluminum hydroxide deposits on the aluminum plates. 

 

  • The plate acts as a high resistor to a low voltage value and vice versa for a critical value.

b.Thyrite Lightning Arrester

 

  • These types of lightning arresters are commonly used for extremely high voltage conditions. 
  • It consists of a ceramic material called Thyrite, which has a variable resistance. 
  • The resistance is inversely proportional to the voltage applied at the ends of it.
  • It contains a disc that is made conductive on both sides by spraying some conducting material.
  •  The disc is contained inside a translucent porcelain container. It is used as a joint in the container.

c.Horn Gap Arrester

 

  • This contains two horn-shaded pieces of metal. 
  • These two are separated by a small air gap and connected in a shunt between each conductor and earth. The distance between the two electrodes is optimum. 
  • This distance is filled with air that ionizes on fault current passage.
