It is placed very near to the equipment and when the lightning occurs the arrester diverts the high voltage wave of lightning to the ground. They are capable of only stopping the leftover voltage surge which got past the grounding system and the lightning arrester.

Valve Type Lightning Arrester And Over Voltages Electrical

Lighting arrester is used to suppress the high transient voltage isolation arc electrical surge currents from spark and lightning currents from lightning strikes.

Lighting arrester diagram. The earthing screen and ground wires can well protect the electrical system against direct lightning strokes but they fail to provide protection against traveling waves which may reach the terminal apparatus. A lightning arrester alternative spelling lightning arrestor also called lightning diverter is a device used on electric power systems and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. After the surge is over the arc in the gap is maintained by the normal supply voltage leading to short circuit on the system.

The climatic conditions eg. The device which is used for the protection of the equipment at the substations against travelling waves such type of device is called lightning arrester or surge diverter. Lp consultants international pvt ltd 195616 views 554.

These are your last line of defense. Lighting arrester is used to suppress the high transient voltage isolation arc electrical surge current s from spark and lightning currents from lightning strikes. The lightning arrester does not have any contact with the power line conductor.

Board type b class and c class surge arresters must be connected in parallel to the system. They cannot protect your electronic devices by themselves. They must be used in conjunction with the grounding system and the lightning arresters.

Rain humidity temperature etc affect the performance of rod gap arrester. In other words lightning arrester diverts the abnormals high voltage to the ground without affecting the continuity of supply. The selection of arrester depends on the various factors like voltage current reliability etc.

In class b c class section 16mm2 minimum we have to use a minimum of 6 mm2. Lightning protection design earthing system design lightning protection for buildings design duration. The typical lightning arrester has a high voltage terminal and a ground terminal.

The lighting arrester is doing the exact duty of surge arrester from outside of the conductor. A lightning arrester or a surge diverted is a protective device which conducts the high voltage surges on the power system to the ground. Types of lightning arresters.

The lighting arrester is doing the exact duty of surge arrester from outside of the conductor. The lightning arrester protects the electrical equipment from lightning. The rods may melt or get damaged due to excessive heat produced by the arc.
