Partial discharge detector

PD1 is a hand-held, pre-screening, tool-based professional live detection
instrument. It can be equipped with 8 external sensors including AA/AE
Ultrasound, TEV ground wave, HFCT high frequency current and temperature
sensor. It is suitable for live detection of various electrical equipment
such as substation, switch station and outdoor.

This instrument adopts acoustic and electric joint detection method, using
transient ground wave (TEV), ultrasonic wave (AE), high-frequency current
sensor (HFCT) and other sensors to comprehensively detect the partial
discharge of power equipment, to achieve direct monitoring of power
equipment such as transformers, switchgear and distribution cables. The PD1
detector can evaluate the insulation condition comprehensively according to
a variety of characteristics, detect the magnitude of partial discharge, and
calculate the time difference between acoustic and electrical signals to
achieve accurate discharge power location.

PD1 has waveform detection, recording and storage functions, and has small
size, light weight, is very easy to operate. It supports wireless data
uploading, cloud platform interconnection, GPS positioning, effectively
preventing line faults and improving power cable reliability.



Product Features:

* Portable design, small size, light weight, easy to carry, single person
can operate;

*5 "high brightness large size touch LCD screen, grasp every detail, easy to
operate;

* The abnormal discharge signal detected by the detector is converted into
audible signal and visual waveform, and the discharge intensity can be
clearly distinguished according to the sound and waveform.

* Embedded GPS receiver automatically stores coordinate data, which is
convenient to query and save detection path;

* With the function of temperature and humidity detection, real-time
detection of ambient temperature and humidity;

* With data saving function, data can be uploaded to the cloud platform to
realize data analysis and review function;

* High sensitivity, directivity and directionality, can accurately locate
the line fault;

* Non-contact detection, detection is effective, safe and reliable;

* Live detection, does not affect the normal operation of the checked
equipment;

* The instrument can be extended to a variety of external sensors, flexibly
used in various detection scenarios;
* Waveform spectrum analysis: analyze the spectrum content of discharge
waveform to make the discharge waveform more comparable, comprehensively
statistical analysis of test data, reduce the influence of non-stability
factors on test results.
