    Abstract: This paper introduces the technological process and operation mode of denitrification and ammonia supply in coal-fired power plants. The Selective Catalytic Reduction (SCR) flue gas denitrification technology of coal-fired power plant is a great significant to environmental protection, which denitrification efficiency is up to 90%. A coal-fired pow... Show More

    Abstract: This research shows that all of the insulation characteristics (insulation resistance, partial discharge, dissipation factor, and alternating leakage current) of HV motor become worse at high temperature. It is also shows that partial discharge and insulation resistance are reduced at moisture absorption. Therefore, to accurately analyze the insula... Show More
