Insulating gas Converter Station device

Insulating gas Converter Station device

For higher voltages, gas-insulated switch gear reduces the space required around live bus. Instead of bare conductors, bus and apparatus are built into pressurized tubular containers filled with sulfur hexafluoride (SF 6) gas. This gas has a higher insulating value than air, allowing the dimensions of the apparatus to be reduced.

    The ac system or systems to which a converter station is connected significantly impact its design in many ways. This is true for harmonic filters, reactive power compensation devices, fault duties, and insulation coordination. Weak ac systems (i.e., with low short-circuit ratios) represent special challenges for the design of HVDC converters.

    At the heart of an HVDC converter station, the equipment which performs the conversion between AC and DC is referred to as the converter. Almost all HVDC converters are inherently capable of converting from AC to DC ( rectification ) and from DC to AC ( inversion ), although in many HVDC systems, the system as a whole is optimized for power flow in only one direction.
