Product introductions
Wuhan UHV Power Technology Co.,Ltd., is a professional manufacturer and supplier of high-voltage power testing equipment in China.The clamp-type earth resistance tester produced by Wuhan UHV is a hand-held earth measuring instrument.Clamp Ground Resistance Tester is equipped with the necessary accessories for testing.Simple and intuitive to operate,operators only need to read the instructions and do not have to attend special training to be able to operate.
Clamp Ground Resistance Tester is used for measuring grounding resistance and evaluating grounding quality on this basis. This instrument is based on our years of experience in the production and development of grounding resistance and electrical installation test equipment..
Excellent grounding system is an important guarantee for safe and reliable operation of electric power, telecommunication and electrical equipment.The magnitude of grounding resistance is the basis for judging the quality of grounding system.Accurate, fast, simple and reliable grounding resistance measurement method has become an urgent need of technical progress in the field of lightning protection grounding. Clamp Ground Resistance Tester is suitable for telecommunication, electric power, weather, machine room, electric power distribution line, tower transmission line, gas station, factory grounding network, lightning rod, etc.
Clamp Ground Resistance Tester not only has the traditional function of measuring Ground Resistance with auxiliary poles, but also has the unique function of measuring Ground Resistance without auxiliary poles. It changes the traditional measuring principle and means of testing grounding resistance: Using the double-clamp non-contact measurement technology, there is no need to use auxiliary poles, and the grounding body is not isolated from the load, so the on-line measurement is realized. In the single point grounding system, strong interference and other conditions, can be used to measure the auxiliary pole.
Production functions
Ground resistance measurement — Measures the ground resistance of grounding systems to assess grounding quality.
Dual-clamp method testing — Requires no disconnection of grounding conductors, suitable for rapid measurement in multi-point grounding and complex grounding sites.
Ground rod method testing — Supports traditional ground rod measurement, suitable for single-point grounding and other scenarios.
Strong anti-interference measurement — Suppresses power grid harmonic interference such as 50Hz and 100Hz, enabling measurement even in high-interference environments like high-voltage substations.
Wide range, high-resolution measurement — Ground resistance measurement range: 0.01Ω to 200Ω, with a minimum resolution of 0.01Ω.
Measurement data storage — Built-in storage function, capable of saving up to 200 sets of test data for on-site recording and subsequent review.
Large-diameter clamp opening — Standard Φ50mm clamp opening, capable of clamping thicker grounding conductors such as flat steel and steel bars.
