Grounding resistor tester UHV-5600

ground bondlightning arrestorfor soil

This double-clamp ground resistance tester UHV-5600 measures grounding resistance and evaluates grounding quality for a variety of sites and installations.

Applications

• Telecommunications systems
• Electric power systems and substations
• Weather stations
• Computer rooms and data centers
• Distribution lines and transmission lines
• Gas stations and factories
• Lightning rods and grounding installations

Features

• Measurement methods: double-clamp method and pile/stake method — suitable for multi-point and single-point grounding.
• Strong anti-interference capability: generates high-frequency current to filter 50 Hz, 100 Hz and other harmonic interference from commercial power supplies, enabling accurate measurements in noisy environments such as high-voltage substations.
• Wide measuring range and high resolution: 0.01 Ω to 200 Ω range with 0.01 Ω resolution; capable of accurate measurement of low grounding resistance (below 0.7 Ω).
• Large jaw design: standard jaw diameter Φ50 mm to accommodate flat iron/steel grounding conductors; custom jaw sizes available on request.
• Large-capacity data storage: stores up to 200 measurement records.
• Easy single-handed operation: compact, lightweight and supplied in an explosion-proof portable case for field measurement.
