GOZ-JFD-2A Partial Discharge Ultrasonic Positioning System
GOZ-JFD-2A Partial Discharge Ultrasonic Positioning System is used in transformer fault detection, quickly ascertain the location of the fault for transformer discharge screens, wire, metal parts and high voltage coil, ultrasonic signal of partial discharge, and also partial discharge ultrasonic measurement of the reactor.
Positioning error is less than 250mm, and the entire measurement system can detect partial discharge less than 1000pC ultrasound signal. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities inspection, and issue a partial discharge ultrasonic positioning system test report.
1. Windows-based software platform, easy and simple operation
2. Ultrasonic sensors with low noise, high sensitivity and anti-jamming performance, high reliable signal
3. Partial discharge ultrasonic signal with power - sound positioning and sound - sound positioning features, more flexible measurement on-site
4. Optionally ultrasonic signal Spherical positioning calculation or hyperboloid positioning calculation, more accurate positioning
5. With a three-dimensional geometry to show the location of the ultrasound probe and Coordinate positioning point
6. Facilitate the establishment of measurement and positioning database for further analysis and management
7. Used as partial discharge monitoring instrument for electrical equipment partial discharge produce and development
