Accurate insight of the condition of transformers is essential for all electrical networks and on-line monitoring of critical transformers has become increasingly important. The knowledge gained from closely monitoring expensive transformers can maximize its longevity and avoid expensive failures.
IOD TGA adopted the advanced infrared photo-acoustic spectroscopy technology and the friendly operation interface. The concentration data of the 8 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
IOD TGA is one of the best tools for the electric equipment asset evaluation.
BENEFITS:
* Fast measuring in the field
Within 20 minutes,8 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
Weights <10 kg, in a rugged and convenient carry case.
* Reliable
Engineered design provides inherent reliability and high accuracy.
* PC communication
PC software allows downloading,trending and analysis of results
*Sample Period
The sample is adjustable,and the minimum period <1hour.
*Reliable Gas Extraction
No use of membranes or vacuum extraction
