Portable Partial Discharge Detector

Multi-Function Detector (acoustic wave + partial discharge + infrared function) uses microphone array technology to collect acoustic wave data, combined with high-definition camera to realize the positioning of acoustic wave. The sound wave distribution data is obtained after analyzing the sound wave positioning technology by beamforming, and then the sound wave distribution data is fused with the video to generate the sound-image cloud image and displayed dynamically on the display screen.

The multi-function PD collector - WiFi version integrates two sensors: ultrasonic and geoelectric waves. It can be used for the detection and evaluation of the insulation state of the switchgear in operation. Connected with the test of contact ultrasonic, UHF, high-frequency transformer and concentrator and other sensors, it can be used for partial discharge detection of transformers, GIS, cables, overhead lines and other equipment in operation.

This product can be widely used in partial discharge(PD) detection of power systems, including insulation status detection of high-voltage switchgear, ring main unit, voltage/current transformers, transformers (including dry-type transformers), GIS, overhead lines, cables and other device. The discharge degree of electrical device is measured by the following indicators:

PD intensity detection: By measuring the discharge signal within a power frequency period, the intensity of PD is characterized according to the maximum value (dB) of the discharge pulse sequence.

PD frequency detection: By measuring the discharge signal in a power frequency cycle, the discharge pulse is extracted and the frequency of PD is characterized according to the number of discharge pulses.

The infrared thermal imager can convert the part of infrared radiation invisible to the naked eye on the surface of the object into a visible image, and the infrared thermal imaging is not affected by visible light, and has the advantages of non-contact temperature measurement, smoke and fog, etc., which is very suitable for temperature detection of electrical equipment.

1.Once a gas leak occurs, the acoustic imaging module can sense the ultrasonic/acoustic waves generated when the gas leaks, so as to locate the location of the leak and give an alarm. The realization of this function is based on acoustic imaging technology, using a microphone array, scanning space sound waves, and determining the fault location through the phase difference of sound waves to obtain an "acoustic image".

2.Automatic diagnosis and analysis of test results, with independent data acquisition and partial discharge signal analysis and diagnosis functions. It can also provide sensor test data and important data such as time domain/PRPD/PRPS map/histogram/time-of-flight map.

3.Wireless WiFi or Bluetooth connection; USB or Bluetooth export test report, Bluetooth playback audio function

4.Configure different sensors to realize the partial discharge detection of almost all high-voltage electrical equipment;

5.Button/touch screen control. Humanized man-machine interface facilitates data management of different devices;

6.Multi-function PD Collector - WiFi version of the precision small structure, accurate data acquisition and diversified measurement principles, can realize the partial discharge detection of various electrical equipment, including ultrasonic, ground wave measurement principle. You only need to change the different sensors, and you can perfectly solve the task of partial discharge detection of high-voltage electrical equipment. It can be connected to special detection sensors such as GIS, transformers, overhead lines, cables, etc.

7.The non-invasive detection method does not require power failure during the test process, and there is no need to configure an additional high-voltage source, which is more convenient to use than the traditional pulsed partial discharge detector;

8.The test bandwidth range is 30kHz ~ 3.0GHz, which is suitable for the detection principle of various frequency bands;

9.By using the image color display and hot spot tracking display function displayed on the screen, it is possible to preliminarily determine the heat condition and fault location, so that the problem can be identified with high efficiency and high accuracy.

10.It can take photos, record screens, and display 30-day historical data trend charts.
