Remote Monitoring of Incipient Faults Using GPRS in Power Transformers

Free registration required

Executive Summary

One of the most applied procedures for detention of incipient faults in power transformers, such as partial discharges, electrical arcing and overheating, is the analysis of the concentration of gases dissolved in the isolating mineral oil. This analysis usually is carried through in a laboratory through chromatography in gaseous phase. Although it presents trustworthy results the chromatography brings some inconveniences as the need of a periodic sampling along with the distance from the laboratory to the substation of electric energy.
