[0002] Building lightning protection refers to the measures taken to protect buildings from lightning strikes or reduce lightning hazards by using different methods according to their lightning protection requirements. The lightning protection system of a building is divided into external lightning protection and internal lightning protection. External lightning protection includes three parts: lightning arrester, down conductor and grounding device, which mainly protect against direct lightning strikes and side lightning strikes, protect the building itself from damage, and weaken the impact on the building when a huge lightning current discharges into the ground along the building. Internal lightning protection includes reasonable wiring, shielding isolation, overvoltage protection and equipotential bonding, etc., which mainly protect against induced lightning and limit the lightning electromagnetic pulse to protect the safety of various electrical equipment in the building. Among them, an equipotential tester is needed when regularly detecting the quality of equipotential bonding between metal components in a building (such as lightning protection belts, ground beams, structures, protection, floor reinforcements, water pipes, radiators, bathrooms, doors and windows, balconies, kitchens, etc.).
