Bi-Directional, Dual Active Bridge Reference Design for ...· PDF fileFigure 1. Role of DC/DC Converter The DC/DC converter must be capable of handling high power levels. In addition to this, the converter must be modular, which enables single power stage converter units to be paralleled, whereby the output power throughput can be scaled to higher levels as required by DC charging station standards. Current
HVDC Cable Transmission· PDF fileThe converter station losses are normally as low as 0.6% per station, and DC cable losses are only around 0.3-0.4% per 100 km. Long AC cables produce high amounts of reactive power, requiring shunt reac- tors at both ends. In extreme cases the reactive current may seriously reduce the

The porcelain post insulator and vertical bushing are both the deep under-rib shed-type, with the minimum spacing of the shed being no less than 95 mm, ratio of the shed spacing to the shed overhang being no less than 1.0, and specific creepage distance being no less than 54 mm/kV.
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
