4-20ma Signal Lightning Arrester Purchase Suggestions

When protecting 4-20mA signal equipment during the thunderstorm season, the following points should be considered when purchasing lightning surge arrester:
Current capacity: Choose a signal surge arresters with high current capacity (such as 10kA to 20kA), especially in areas prone to lightning.
Low residual voltage: Ensure that 11kv lightning arrester can limit the residual voltage to the equipment's tolerance range when a surge occurs. Generally, residual voltage below 1.0kV is more ideal.
Response time: The response time of 15kv lightning arrester should be fast enough, usually less than 25 nanoseconds, to ensure that the equipment can be quickly protected when lightning strikes.

Using 4-20mA signal lightning arrester in transformer to protect sensors and control systems during the thunderstorm season is an important means of lightning protection. The risk of damage to equipment from lightning strikes and surges can be greatly reduced by properly installing high voltage lightning arrester, grounding, and taking multi-level protection measures. At the same time, regularly maintaining the status of 33kv lightning arrester to ensure effective protection when lightning strikes frequently is the key to ensuring the safe operation of equipment.
