Technical Specifications

Installation requirements

The digital meter of DC lightning arrester should avoid strong vibration and impact during installation. This is because vibration and impact may cause damage to the mechanical structure and electronic components of the meter, thereby affecting its stability and accuracy. In order to ensure the long-term stable operation of the meter, necessary shock absorption and fixing measures should be taken during installation. The digital meter of DC lightning arrester should ensure good grounding and lightning protection measures during installation. Grounding is the key to ensuring the safe and stable operation of meters. It can effectively introduce lightning strikes and overvoltages into the ground, thereby protecting meters and power equipment from damage. At the same time, lightning protection measures are also essential, as they can further reduce the threat of lightning to meters and power equipment. During installation, grounding and lightning protection treatment should be strictly carried out in accordance with relevant standards and specifications.
