What is a lightning arrestor?

Thunder arrestors, commonly known as lightning arresters, are crucial devices in safeguarding electrical systems from the devastating impacts of lightning and other voltage surges.

How does a lightning surge arrester work?

an induced surge on the system. In the second case, the lightning ge is much lower in amplitude. In most cases, the lightning surge is reduced to safe levels for insulation and the a ster is ready for the next one. The surge arrester protects the power systems from both the direct and indirect lightning surge by divertin

Can lightning arresters be used in power systems?

Therefore the results gent.

Does a lightning surge damage the arrester?

uce the lightning surge to zero. Instead it reduces it to a level that wi generally not damage equipment. In some cases, the lightning surge tra eling down the system after it isHowever a lightning surge can damage the arrester in two ways ( although a rare cas

What is a 245 kV lightning arrester?

Up to 245 kV lightning surges and beyond 245 kV switching surges are found to be more severe, Section 18.3. It is customary, therefore, to call an arrester up to 245 kV a lightning arrester and beyond 245 kV a surge arrester. For ease of reference, we have described them as surge arresters or only arresters for all types.

What voltage should a lightning arrester be rated at?

which is much below the BIL of the equipment (1300 kV) as in Table 13.3. One can therefore safely select the arrester with a higher rated voltage, Vr, at 381 kV and a Vres at 957 kV. Note A lightning surge protective level is found to be more stringent than the switching surge or FOW protective levels.
