General Information
GDJF-2007 Digital
Partial Discharge Analyzer is widely used for detecting partial discharge of
high voltage equipment such as power transformers, instrument transformer, HV circuit
breaker, GIS, Zinc oxide surge arrester, power cable. It also can make type
tests and monitor insulation operation.
It includes main unit, PD software, current
transformer, input unit, calibration pulse generator, input adapter, antenna
amplifier and connection cable etc..
Features
-
12 inch
LCD display, with portable design, rugged and durable, easy to use.
-
Strong
anti-interference ability, accurate. Using digital filtering technology, field
interference can be effectively eliminated, and partial discharge measurement
can be realized in a strong interference environment.
-
Multi-channel
data acquisition. One screen can display 2 channels or 4 channels waveform.
-
Powerful
software function. With PD measurement, analysis, PD repeated discharge times N
measurement, analysis and anti-fixed interference, anti-dynamic interference.
Free choice of ellipse, straight line and sinusoidal display mode. Measure and
Observe discharge pulse by window, and test voltage and current, partial
discharge can be measured at the same time. All test data of 2 channels can be
saved timely. Test waveform can be saved, re-displayed and analyzed. The gain
range of each channel can be coarse adjusted and fine adjusted. Digital
window-opening technology, to avoid the influence of interference on
measurement. Phase window opening, single window and double window can be
selected. Window can be opened freely within 360 degree.
-
Accorded
with IEC 60270 standard.
