Measuring and control devices have a wide range of applications such as production plants, building management, heating systems, alarm devices, etc. Overvoltages due to lightning or other causes are harmful not only to control systems but also to expensive converters and sensors. Failure of control systems usually leads to product loss and impact on production. Measurement and control units are usually more sensitive to surge overvoltages than power supply systems.
Cautions Editorial Podcast When selecting and installing lightning protectors for measurement and control systems, the following factors must be considered. 1, Maximum operating voltage of the system 2, Maximum operating current 3, Maximum data transmission frequency 4, whether the resistance value is allowed to increase 5, whether the conductor is introduced from outside the building and whether the building has external lightning protection.
Caution Editorial Podcast 1, Please recognize the interface and the connection method. 2, identify the signal lightning protector input/output interface identification, input to the external line, output to the equipment. 3, grounding wire should strive to short, thick, straight, in order to reduce the impact of distributed inductance on the lightning strike electromagnetic pulse capacity discharge. 4, signal lightning protection device grounding is appropriate through the electronic switch and ground network connection.
