The instrument adopts ultra-high frequency (UHF) and ultrasonic (AE) detection technology, selects high-performance sensors, and cooperates with optimized hardware and software and structure

UHF and ultrasonic have good response to GIS and partial discharge such as free metal particle discharge, suspended potentiometer discharge, surface discharge, air gap discharge inside insulating parts, metal tip discharge, etc

It is suitable for on-site investigation and use. It is an essential instrument for the operation and maintenance department of substation equipment. It is widely used in power systems and railways
