MOSAD®-MST-PD monitoring system
The life of a transformer is limited by the life of its paper insulation which is significantly shorter than the life of other construction parts. Among parameters indicating the actual condition of the paper insulation, the presence of partial discharge is the most important. To detect the partial discharge occurrence, its level of activity and localization the MOSAD®-MST-PD diagnostic and monitoring system has been developed.
Insulation system of oil power transformers consists of combination of mineral oil and cellulose paper, accordingly materials very sensitive to the degradation of operational factors and aging of which may considerably influence the trouble-free operation of the transformer.
Applicable for commercial use, MOSAD®-MST-PD diagnostic and monitoring system has been produced following the practice and test analysis of MOSAD®-PD-UHF prototype which was one of the results of the FR-TI1/001 project realised in cooperation of TES s.r.o. (Czech Republic), EGU-HV Laboratory a.s. (Czech Republic) and Technical university of Brno (Czech Republic). The project was funded by Ministry of Industry and Trade of the Czech Republic.
Diagnostic and monitoring system MOSAD®-MST-PD won award Golden Ampere at the 24th International fair of electrotechnics, electronics, automation, communication, lighting and security technologies in 2015:
