Product introduction
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.
The clamp ground resistance tester manufacturer is used for measuring grounding resistance and evaluating grounding quality on this basis. The earth resistance tester supplier 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.
Earth 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 function
1. Double-Clamp Non-Contact Measurement: Enables true on-line grounding resistance measurement—no auxiliary poles needed, and no need to disconnect the grounding body from its load.
2. Dual Measurement Methods: Offers both double-clamp and ground pile (auxiliary pole) modes. The double-clamp mode works at any grounding site; the pile mode suits single-point grounding systems or strong-interference environments.
3. Wide Measurement Range: Covers 0.01Ω–200Ω with 0.01Ω minimum resolution, and measures grounding resistance below 0.7Ω accurately.
4. High Accuracy: ±3% ±2 digits for the double-clamp mode; ±2% ±2 digits for the pile mode.
5. Strong Anti-Interference: A high-frequency current suppresses 50Hz, 100Hz, and other harmonic interference from commercial power—accurate results even in 500kV substations.
6. Large Jaw Design: Standard Φ50mm jaw fits flat iron or steel grounding leads; custom jaw sizes available.
7. Data Storage: Holds up to 200 measurement data sets.
8. User-Friendly Operation: English interface, compact (265×130×65mm) and light (0.8kg with battery), supplied in an explosion-proof portable case for easy field use.

Frequently Asked Questions
Q:Why should grounding resistance be tested regularly?
A:Grounding resistance can change over time because of corrosion, soil conditions, loose connections, construction work and environmental changes. Regular testing helps identify potential grounding problems and improves the safety and reliability of electrical systems.
Q: What test methods does the ground resistance tester support?
A: It supports both the dual-clamp method and the ground rod method. The test method can be selected based on different grounding systems and on-site conditions.
Q: Can the ground resistance tester be used in high-interference environments?
A: Yes. It features strong immunity to power frequency and harmonic interference, making it suitable for complex electrical environments such as substations.
Q: What is the delivery lead time for bulk orders?
A: The delivery lead time depends on the order quantity, product configuration, and customization requirements. The specific time is subject to order confirmation.
Q:What is a double clamp ground resistance test?
A:double clamp ground resistance test uses two clamps around the grounding conductor. One clamp generates the test signal while the other detects the resulting current, allowing the instrument to calculate the resistance of the grounding loop without requiring traditional auxiliary ground rods in suitable systems.
