RSJF-9002 Handheld Ultrasonic LED Screen Partial Discharge Test
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.
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
10,Easy to use, small size, light weight, easy to carry.
