Positive corona discharge of rod‐plate electrodes in high‐speed airflow
High Voltage, EarlyView.Abstract The characteristics of positive corona discharge of rod electrode in high‐speed airflow are studied in this paper. The experiments were carried out in a wind tunnel with a maximum flow speed of 100 m/s in a dark room. The discharge voltage and current were recorded and the corona patterns were captured by a digital single lens reflex (DSLR ...

Temperature rise characteristics of C5F10O/CO2 gas mixture AC high voltage switch bus
High Voltage, EarlyView.Abstract C5F10O/CO2 gas mixture is one of the most promising alternatives to SF6 as an insulating gas in high‐voltage switchgear. As a key performance index in product design, the temperature rise characteristics are rarely reported. In this paper, the thermodynamic parameters of C5F10O/CO2 gas mixture were calculated first. Then, the calculation model

High Voltage, EarlyView.Abstract Transformers are widely distributed and extremely important energy conversion equipment in the power system. However, the high altitude electromagnetic pulse (HEMP) can induce a steep pulse voltage with a peak value of up to thousands of kilovolts on the overhead line, and the frequency is up to 100 MHz, which is easy to damage the transformer
