GFUVE GF2011 Wireless High Voltage Current Clamp Meter Leakage Tester

 Power grid leakage loss and transformer ratio inspection have always been core daily tasks for power operation teams. The GFUVE GF2011 wireless high voltage clamp meter integrates leakage detection and high-low current ratio testing to simplify your field inspection workflow significantly.

Crafted with advanced CT sensing and masked digital integration technology, this all-in-one tester supports dual-purpose measurement. Pair it with the matching 5m segmented insulation rod rated for 100kV dielectric strength to safely test energized circuits up to 69kV; remove the rod and it works as a precision low-voltage clamp meter for indoor cabinet detection. Its 50mm large-diameter clamp jaw fits most overhead bundled cables, capturing ultra-fine leakage current starting at 0.01mA all the way up to 1200A load current with stable ±1% measurement accuracy.

The built-in wireless module delivers steady 30-meter signal transmission that penetrates walls, transformers and other site barriers, letting technicians operate at a safe distance without temporary power cut-offs. The handheld receiver features a backlit 4-digit LCD, peak hold and data lock functions, plus storage capacity for 99 groups of on-site records to calculate primary and secondary loop transformation ratios manually afterward. Every component is built for harsh outdoor environments: the telescopic insulation rod resists moisture, high temperature, impact and bending, while the anti-drip meter body operates reliably between -25°C and 40°C. It offers 10 hours of continuous runtime with alkaline batteries, paired with low-battery reminder and 15-minute auto-shutdown to conserve power. Fully compliant with IEC global safety and EMC standards, the complete kit includes the clamp sensor, wireless receiver, portable protective case and full set of batteries for one-person independent field work.

This versatile tester is widely adopted by power anti-theft inspection departments, property electrical teams, power engineering contractors and industrial mining electrical maintenance divisions worldwide.
