Test 69kV Lines Safely | GF2011 Wireless Clamp Ammeter

Conventional 69kV line measurement demands power cuts, temporary safety barriers and multi-person crews, dragging down daily grid inspection efficiency and raising operational expenses. The GF2011 wireless clamp ammeter delivers live-line testing without power shutdowns, streamlining your overhead circuit patrol workflow entirely.

Supported by a full 5m segmented insulation rod with 100kV AC dielectric withstand rating, it creates reliable isolation for operators when testing all circuits below 69kV. Its long-range 30m wireless signal penetrates walls, transformers and substation obstacles, letting users read real-time current values from a secure distance away from energized conductors. No extra scaffolding or climbing gear is required for most overhead wire detection tasks.

Equipped with a 50mm large-diameter clamp jaw, the unit clamps and removes conductors while powered on without disrupting grid operation. Advanced masked CT sensor technology delivers consistent ±1% accuracy across the full 0.00mA to 1200A measuring spectrum, with ultra-fine 0.01mA resolution to capture subtle leakage currents that trigger hidden grid losses. Built-in peak hold, data lock and 99-set data storage allow technicians to record field readings and manually calculate primary-to-secondary transformer ratios later for equipment condition analysis.

The backlit 4-digit LCD guarantees clear visibility in dawn, dusk and shaded substation spaces. The whole set adopts anti-drip construction, paired with weather-resistant insulation rod that withstands temperatures ranging from -25°C to 40°C, resisting moisture, heat and collision damage during long-term outdoor patrol. Standard alkaline batteries support up to 10 hours of continuous testing, complemented by low-battery reminder and 15-minute auto power-off to extend battery service life. Every component complies with IEC1010 and EMC international safety standards, fully meeting global power industry operation specifications.

The complete portable kit contains clamp sensor, handheld receiver, matched batteries and protective storage case, ideal for single-person independent field work for power distribution companies, mining electrical departments, substation maintenance teams and power anti-theft inspection units worldwide.
