Brief Introduction
The grounding grid resistance tester is widely used in many on-site testings, like substation or other power supply occasions, to test the grounding resistance and relative parameters. The tester is integrated design with built-in variable frequency power module, output power continiously variable frequency and adjustable. The frequency can switch to 45Hz or 55Hz, built-in high speed processor core, advance digital wave filter technology, which is effectively avoiding power frequency occasion's interference to the testing.
