Determining insulation condition of 110kV instrument transformers. Linking PD measurement results from both gas chromatography and electrical method
Working methods for on site testing of insulations: Gas chromatography (using the TFGA-P200 chromatographer); Electrical measurements of partial discharge levels using the digital detection, recording, analysis and partial discharge acquisition system, MPD600. First performed, between 2000–2015, were the chromatographic analyses concerning...

Factors that increase the electric field of the dielectric barrier ozone generators
The dielectric barrier discharge cell (DBDC), also called ozone cell, is the main component of the ozone generators widely used. When the cell is powered with a high voltage value (> 5 kV) in the dielectric gas, arises a high intensity electric field that influences ozone generation processes by silent discharge also called dielectric barrier di...
