PDGA™ － Portable Dissolved Gas Analyzer represents a new generation of test equipment for analysis the dissolved gas in oil. PDGA adopted the advanced infrared photo-acoustic spectroscopy technology and the friendly operation interface. The concentration data of the 7 key fault gases and moisture can be drawn directly within 20 minutes in the field. It really can take place of the Gas Chromatography system in the laboratory because of the accurate, rapid, reliable results. Thus the PDGA is one of the best tools for the electric equipment asset evaluation.
Analysis of dissolved gases in the oil is an established technique in this field, and is being further extended to other oil filled equipment, such as power transformers, tap-changers, circuit breakers.
* Fast measuring in the field :
Within 20 minutes, 7 key fault gases and moisture can be read
* No consumables :
Pure physical photo-acoustic spectroscopy technology,
The consumables of calibration gas and carry gas are needless.
* Moisture in the oil :
The concentration of moisture in the oil can be given during the same one test，±1ppm
* Simple :
Step-by-step software guides and touch screen, the user pass through the procedure.
* Portable and rugged :
Weighs <10 Kg, in a rugged and convenient carry case.
* Reliable :
Engineered design provides inherent reliability and high accuracy.
* DGA diagnosis :
International general faults gases diagnosis method, preset the warning limits.
Roger’s ratios, Duval’s Triangle, IEEE key gases
* PC communication :
External PCs is possible via USB connections, allowing databases to be imported or downloaded.
* Samples : Oil and gas
