    Notes from Leak Amplifier Owners: 1) Stereo 20 power transformers appear to have been revised during the production run. Early models had 300-0-300 volt HT secondaries, but this was revised to 280-0-280 V, possibly from a propensity for this transformer to overheat. The Leak circuits do not document this change. Comments from owners are welcome.

    Thus, the common mode leakage current may follow through the parasitic capacitors between photovoltaic system and ground [9]. This leakage current increases system losses and grid current harmonics and leads to serious unsafety [10]. Therefore, the common mode leakage current must be taken into account in designing transformer-less PV inverters.

  • Significance of CO2/CO ratio in - Transformers Magazine

    AbstractIntroductionCarbon Monoxide and Carbon Dioxide in Transformer OilCase 1According to the literature, the ratio of carbon dioxide and carbon monoxide (CO2/CO) for a transformer with a healthy cellulose insulation system should be between 3 and 11. If results of the dissolved gas analysis (DGA) of oil from transformers in service give the ratio value of CO2/CO less than 3, it means that the cellulose insulation is degrading rapidly. What is the meaning of this ratio if it is high; say greater than 15 or 20? Keywords:carbon monoxide, carbon dioxide, ratio, dissolved gas analysis
