SGDW-5A Ground Grid Tester | Class A lightning protection testing equipment | A high-precision testing instrument used for measuring grounding resistance and related parameters. This instrument features small size, light weight, easy portability, strong anti-interference performance, and high accuracy. It adopts an integrated structure with a built-in variable frequency power supply module, and the output power supply can be continuously adjusted with variable frequency. The frequency can be changed to 45Hz or 55Hz. It is equipped with a high-speed processor core and uses high-end digital filtering technology, effectively avoiding the interference of power frequency electric fields on testing, fundamentally solving the problem of accurate measurement under strong electric field interference. The 5A different-frequency ground grid grounding impedance tester is referred to as the ground grid tester; it is suitable for testing the power frequency grounding impedance, contact voltage, step voltage, and other power frequency characteristic parameters of various grounding devices, as well as soil resistivity. It can test substation ground grids (4Ω), thermal and hydro power plants, microwave stations (10Ω), lightning rods (10Ω), and various other sites;
SGDW-5A Ground Grid Tester | Class A lightning protection testing equipment A large number of field tests and user applications show that when the lightning protection device instrument is used for grounding grid testing in the harsh electromagnetic environment of operating substations, the measurement data of the different-frequency ground grid grounding impedance tester is accurate, stable, and repeatable. It is an ideal instrument for measuring the characteristic parameters of large and medium-sized grounding grids.
