Product Description

Ultrasonic Handheld pd tester Partial Discharge Detector Pd Tester Partial Discharge Meter

I.Product overview      
   Digital partial discharge detector is a special instrument for measuring and analyzing insulation performance of power equipment. This system adopts modern electronic and computer integrated technology, realize signal(analog, electronics, digital) amplification , filtering, data acquisition, data processing, graphic display, and automatic test report  generation, so as to complete the partial discharge measurement and analysis.
  This instrument is easy to carry, and with fast measurement, strong anti-interference ability, which is easy to use on site. Its configuration software is with functions such as time-domain graphics, 2D, 3D statistic map, alarm history, history largest, pulse counting. The software can also enquire and analyse a phase waveform in detail and the window can be zoomed in and out at will. It can also analyze the spectrum of the data, analyze the spectral content of the discharge waveform, make the discharge waveform more comparable, and comprehensively analyze the test data to reduce the influence of the non-stability factors on the test results.Automatic or manual record are used to keep test data and transient discharge waveform which can provide reference for later data analysis.

IV. Add a new patrol test list when start system software for the first time 

According to user's requirement, the system software can be used to build test list for each test, fill in the test specification information, save the test data, so as to match the detection data with the detection information.
When the software is first started, the "Test Settings" dialog box will appear to alert users to fill out the test information, at the same time to see the test list and delete a test. When you click on a trial test list, the experiment area will show the corresponding information.
If you click the cancel button and do not build your own test list, the system software can also quickly establish the default database quik_test.db3 to ensure that the test data is stored.
The software will set up a storage directory in the SD card to save the data, for example:

The test name is: JYPD The data Storage path is: Storage Card\ test management \JYPD\
All of the test raw data is saved in a binary way to save storage space, and all the record data is stored in the SQLite database to be used for generating reports.
The test data of this system is stored in SD card, and the SD card has the maximum support of 32G, which can be exported to PC for backup. Historical data can be loaded into the system for tracking analysis.
