Ensuring the safety of voltage and current circulation is vital for both physical safety and financial reasons. A surge arrester is among the primary systems that provide this security. In cases such as static electricity accumulation in the system or lightning events, surge arresters are used to prevent damage to the installation and the equipment used. However, it is not possible to say that surge arresters provide 100% security. On the other hand, to avoid repair and replacement costs, it is beneficial to take precautions regarding surge arrester burnout (failure).

What are the Causes of Surge Arrester Failure?

Burnout can have many causes. Incorrect connections, choosing a surge arrester that cannot handle the current in the system, or neglecting routine maintenance will cause surge arrester failure. While it is possible to prevent user-induced errors when inspections and maintenance are performed frequently, the risk of high voltage is always present.

Exceeding the Upper Voltage Limit

It is impossible to predict the exact voltage and current measurements of lightning. Although it is partially possible to take precautions with multiple surge arresters placed at specific intervals, exceeding the upper limit is always a possibility. Even if the surge arrester selection is made according to the needs of the installation, it is not possible to completely escape this risk. Therefore, to prevent voltage and current spikes caused by lightning and static electricity from damaging the surge arrester, overvoltage damping elements must be used.

Factors Depending on Location and Climate

Surge arresters can malfunction in dusty, humid, and damp environments. Especially in coastal regions, surge arresters must be cleaned frequently and kept free from moisture and humidity. If the components in the hardware corrode, surge arrester burnout is inevitable. It should also be noted that if this situation is not noticed and the necessary maintenance is not performed, the surge arrester will fail to provide protection.

How to Prevent Surge Arrester Failure?

• Surge arrester selection should be made appropriately for the facility; hardware should be chosen after measuring grounding resistance and voltage values.
• The system should be constantly checked against conditions such as humidity and dust, and necessary maintenance should be performed.
• According to the scale of the facility, it is possible to prevent the upper voltage limit from being exceeded by placing multiple surge arresters at specific intervals.
• If there is a faulty surge arrester in the facility, it should be replaced the moment it is noticed.

By implementing these, precautions can be taken to some extent. However, the risk does not disappear completely. As it would be difficult to provide constant monitoring, even the slightest overlooked factor can cause the surge arrester to become inoperable. This will bring about replacement costs.

What Does a New Generation Surge Arrester Do?

If a new generation surge arrester is installed in an electrical system, there is no need to use any other Class B, C, or D surge arrester. This is because the new generation surge arrester damps overvoltages on one hand, while on the other hand, it prevents damage to electrical systems by blocking internal and external current peaks from entering the system. Furthermore, it does not malfunction due to humidity, dust, or dirt in the environment, allowing for long-term use.

The upper voltage limit of new generation surge arresters is significantly higher than any standard surge arrester, and exceeding this limit is considered an extraordinary event. However, in such a case, the new generation surge arrester automatically disconnects the grid connection, preventing the current from being directed to the installation. In this respect, it can be said to be safer and more functional than standard surge arresters.

New generation surge arresters also perform the functions of Class B, C, and D arresters in the places where they are used, contributing to the prevention of failures such as surge arrester burnout in facilities where arresters are installed. You can protect your home and workplace from lightning by using new generation surge arresters.
