Distribution box surge protector: an important part of lightning
2. Multiple protection: The surge protector has multiple protection functions and can simultaneously protect against threats such as lightning, voltage mutations, and electromagnetic
Installation of lightning protection devices for distribution boxes
Install surge protection devices (SPDs) as close as possible to the power supply entry, ensure proper grounding, and coordinate with external lightning protection systems to protect the distribution box and downstream equipment.Key Installation Steps1. Qualified Personnel and Safety: Only qualified electricians familiar with national and international standards should install lightning and surge protection devices. Safety equipment such as gloves, helmets, and insulated tools must be used during installation . 2. Placement of Surge Protection Devices (SPDs):Type I SPDs (lightning current arresters) are installed at the main distribution board, upstream or downstream of the electricity meter if the building has external lightning protection or overhead line feed. They divert high-energy lightning currents safely to earth and limit voltage to below 6 kV .Type II SPDs are installed in sub-distribution boards to protect downstream equipment, limiting voltage to below 4 kV. If no external lightning protection exists, Type II SPDs are installed downstream of the electricity meter .SPDs should be installed as close as possible to the power supply entry point to minimize line lengths and maximize protection . 3. Grounding and Earthing:Connect SPDs directly to a low-resistance earth termination system. The earth resistance of the complete installation should not exceed 10 ohms, and individual earth electrodes should be tested to ensure proper conductivity .Use copper or stainless steel rods for earth pits, especially in low-resistivity soils (
