Product Highlights
High Sensitivity
Self-developed high-sensitivity sensors offer an equivalent height of up to 15 mm, delivering industry-leading precision in capturing weak partial discharge signals.
Wide Dynamic Range
A dynamic range of ≥70 dB covers full-scale monitoring needs, from weak pulses to severe discharges.
Accurate Positioning
With 250 MB/s high-speed sampling and a positioning error of ≤0.3 m, the system accurately locates faults and reconstructs discharge signatures.
Intelligent Analysis
With a partial discharge alarm recognition accuracy of over 99%, the system effectively reduces false alarms and supports accurate GIS insulation condition assessment.
