The CN B 2 -X 2 + molecular emission spectrum is used to measure both the vibrational and rotational temperatures in atmospheric pressure arc jet discharges. The vibrational and rotational temperature effects on the synthetic diatomic molecular spectra were investigated from the v ,v = 0,0 band to the 5,5 band. The temperatures obtained from the synthetic spectra compared with the experimental ...

Considering the number of failures in high voltage power transformers caused by problems in bushing and winding insulation, it is important to study means for diagnosing incipient failures, to avoid long unavailability periods and its consequences. The aim of this work is to study detection and measurement procedures, concerning the evaluation of position of partial discharge inside the transfo...

Expert systems are used for evaluating the actual state and future behavior of insulating systems of high voltage electrical machines and equipment. Several rule-based expert systems have been developed in cooperation with top diagnostic workplaces in the Czech Republic for this purpose. The IZOLEX expert system evaluates diagnostic measurement data from commonly used off-line diagnostic method...
