HC-136C Acoustic Imaging Instrument

The HC-136C features an all‑aluminum alloy fuselage, balancing reliability with aesthetic appeal—professional yet stylish. Its built-in FPGA chip handles the primary imaging computations, significantly boosting processing efficiency and dramatically reducing power consumption. As a result, the HC‑136C can operate continuously for over six hours; in typical applications, it requires recharging only once every two to three days, or even once a week. The HC‑136C supports multiple operating modes, including single‑source, multi‑source, and sound‑field distribution, and offers automatic partial discharge type identification and leakage estimation, making it well suited for partial discharge and leakage detection. Compact in size yet powerful in functionality,

Online Monitoring of SF6 Density and Moisture Content

As unattended substations evolve toward networking and digitalization, and as demands for remote control and telemetry increase, online remote monitoring of the density and trace‑water content of SF6 electrical equipment has become of significant practical importance.

Live-line testing services

Substation testing services include: power quality assessment, substation infrared thermography, partial discharge detection, zero‑value insulation testing, porcelain insulator flaw detection, ultraviolet inspection, DC system testing, grounding grid impedance measurement, circuit breaker mechanical characteristic analysis, intelligent substation patrol, metal detection, instrument and meter calibration, maintenance, drone‑based inspections, live‑line cleaning, X‑ray inspection, and more.
