The Role of Surge Arresters in Protecting Overhead Power Systems

Lightning arresters play an important role in protecting overhead power systems, mainly in the following aspects

Prevent lightning damage

Lightning arresters can effectively guide lightning current into the earth, preventing lightning strikes from directly causing serious damage to power equipment and lines.

Keep device safe

Avoid damage to transformers, switchgear and other electrical equipment by suppressing transient overvoltages caused by lightning.

Reduce the frequency of equipment being impacted, thereby extending its service life and reliability and reducing maintenance costs.

Improve power supply reliability

Effectively prevent failures caused by lightning strikes, thereby reducing the occurrence of power outages and improving the continuity and reliability of power supply.

Reduce failure rate

Lightning arresters can effectively reduce the failure rate caused by overvoltage. By preventing equipment damage due to overvoltage, power outages and their resulting economic losses and social impacts are avoided.

Maintenance and monitoring

Modern arresters are usually equipped with monitoring devices that can monitor their working status and performance in real time, so that problems can be discovered and maintained in a timely manner to ensure their normal operation.
