MEUBA-10 Visual ultrasonic partial discharge inspection instrument Send email to us

1. Portable design, small size, light weight, easy to carry, one person can operate.
2. Handheld non-contact, visual, audible and display waveform, live non-contact detection.
3. It can scan the open (open-air) equipment of the transformer station live, find and locate various partial discharges: corona, arc, flashover, creepage, wire breakage, arcing, etc.
4. Find and locate the discharge of insulators on the tower, creepage of open-air cable heads, and partial discharge detection and positioning of underground cables;
5. In the handover and preventive tests of the power system, the partial discharge test of the main transformer and GIS, the device is used in conjunction with the partial discharge instrument. If there is partial discharge, it can be distinguished whether it is internal discharge or external discharge. If it is external discharge, the specific discharge point can be located.
6. In the factory tests of large oil-immersed transformers, dry-type transformers and GIS manufacturers, the device is used in conjunction with the partial discharge instrument in the partial discharge test. If there is discharge, it cannot be seen on the screen of the partial discharge instrument whether it is internal discharge or external discharge. Use a handheld inspection and locator to scan the test product. It can quickly find and locate the external discharge point. If there is no external discharge, it is judged as internal discharge.
7. Leakage detection of high-pressure sealed gas and liquid.
8. The 3-megapixel high-definition camera can easily focus on the fault point and take pictures of the tower logo and faulty equipment.
9. The embedded GPS receiver automatically stores coordinate data and provides GPS navigation function, which is convenient for querying and saving the detection path.
10. It has the function of detecting temperature and humidity, and can detect the ambient temperature and humidity in real time.
11. It has data saving function and can realize data playback function.
12. The display screen is a color touch screen, which is convenient for detection and use by detection personnel.
13. The green laser with moderate intensity is easy to track by human eyes in the sun.
14. It has high sensitivity, directionality and directivity, and can accurately locate line faults.
15. It is dedicated and has strong focusing ability. It can be inspected on vehicles with a driving speed of 30km/h.
16. Ultrasonic detection can be applied to noisy environments and is not affected by environmental sounds.
17. The detection adopts non-contact method, and the effective detection distance can reach 30 meters, which is safe and reliable.
18. Use the inspection background software to conveniently manage data and conduct evaluation.
