Complex substation layouts, wall barriers and transformer blocks often disrupt remote signal reading for traditional HV measuring tools — GF2011 solves this pain point with robust 30-meter barrier-penetrating wireless transmission, delivering stable real-time data no matter the site obstacles.
This industrial-grade clamp ammeter pairs seamlessly with a 5m segmented insulation rod with 100kV AC insulation strength, enabling safe live-line tests on power lines up to 69kV. Its advanced CT sensing and masked digital chip technology delivers ultra-wide measuring coverage from micro 0.00mA leakage signals to 1200A heavy load current, with 0.01mA high resolution and consistent ±1% accuracy across full measurement range.
The separated handheld receiver features a backlit 4-digit LCD for clear readings in low-light substation environments, built-in peak hold, data lock and storage for up to 99 groups of field records. You can store test data on-site to manually calculate primary and secondary loop current ratios for transformer performance diagnosis later. The anti-drip meter body and multi-section insulation rod are engineered to resist moisture, high temperature, impact and bending, operating steadily under -25°C to 40°C wide temperature range for all-year outdoor patrol. Powered by matched alkaline batteries, it supports 10 hours of continuous testing, equipped with low-battery reminder and 15-minute auto shutdown to extend battery lifespan. Fully compliant with IEC1010 and EMC international safety standards, the complete package contains clamp sensor, wireless receiver, protective storage case and full set of batteries for independent single-person field operation.
Perfect fit for distribution grid patrol, power anti-theft inspection, mining electrical maintenance, power plant routine testing and property electrical fault troubleshooting.
