RSJF-9002 Handheld Ultrasonic LED Screen Partial Discharge Test Transformer Tester
Product Introduction
Ultrasonic discharge detector is applied to partial discharge live circuit detection of transformer, reactor, generator, transformer, bushing, GIS, power cable, power capacitor, CVT, arrester, high voltage switch, switch cabinet and other ac/dc high voltage electrical equipment with various voltage levels and capacities.When partial discharge occurs, physical phenomena such as ultrasonic wave, heat wave, light wave and magnetic wave will be generated. The ultrasonic wave will spread around in the form of spherical wave with the sound source as the center. RSJF-9002 Ultrasonic discharge detector USES the Ultrasonic signal generated by local discharge to judge the existence and location of local discharge. Combined with the real-time images and data, it can quickly diagnose the status of local discharge. The tester integrates transient voltage to ground and ultrasonic.
Products Features
1,Ultrasonic and TEV local emission waveform are at the same interface with yellow, green and red warning values, which is the first in China.
2,Taking dBmV as the unit, transient ground voltage (TEV) and ultrasonic wave were used to detect the size of partial discharge.
3,Color LCD screen, display effect more intuitive, more friendly.
4,The earphone monitoring mode is added. In the ultrasonic mode, the real-time monitoring of local amplifier signals can be realized through the earphone.
5,The display can always display waveform, and can store valuable waveform, test data automatic storage, is conducive to test records and test data follow-up analysis.
6,High signal amplification and sensitivity; Signal reception range: effective distance 15m.
7,Moderate intensity red laser tracing, focusing ability, accurate positioning, safe and reliable, simple and practical.
8,Discover and locate the insulator discharge on the tower, and the creepage of the open cable head.
9,It is mainly used to detect partial discharge of high voltage switchgear.
10,Easy to use, small size, light weight, easy to carry.
