Surface charge migration and dc surface flashover of surface

Jan 11, 2017 · Download figure: Standard image High-resolution image To date, the consensus of researchers is that charges accumulating on the surface of insulators under dc voltage distort the local electric field and pose a potential hazard by reducing the flashover voltage, which restrains the development of HVDC gas insulated switchgears (GIS) or GILs [17–20].

A pulse-tube cryocooler recondenses evaporated helium to liquid at 4.2 K filling the helium vessel of the cryostat at an equivalent cooling power of 0.69 W. To reduce the transmission of vibration to the highly sensitive CCC, the titanium support systems of the cryostat were optimized to be as stiff as possible while limiting the transmission
