What is an HVDC (High Voltage Direct Current) Transmission ... HVDC converter transformer can be built as three-phase units or as single-phase units depending on voltage and power rating. When built as three-phase transformers there is generally one unit with the valve winding arranged for star connection and the other unit for delta connection. In single-phase design, the two valve windings are generally built on the same transformer unit.

Health index and risk assessment models for Gas Insulated ...· The failure rate of Gas Insulated Switchgear (GIS) operating under tropical conditions is about twice the value reported by the third CIGRE's survey in 2007. Three major failure modes that lead to catastrophic failure of a GIS in tropics are the insulation breakdown, the primary joint-conductor failure, and the driving mechanism failure.
High voltage on-site power transformer testing - EE Publishers these cases external high voltage test equipment comes into service. For this purpose, converter-based variable frequency test systems have been developed as the industry standard [3]. Requirements for on-site high voltage testing. High voltage testing is aimed at ensuring the integrity of insulation in a high voltage transformer.

ABB Q&A: From switchgear to HVDC and beyond - POWERGrid ... recently unveiled its first energy storage project and opened a new product development center in Connecticut. Cloud computing and robotics are additional endeavors for the ever evolving firm.
BPA Puts Modernized Celilo Converter Station into Service ... Pacific Direct Current Intertie, a high-voltage direct current system (HVDC), was a marvel and a model when it was energized in 1970. Direct-current systems can move large amounts of electricity over long distances more efficiently than alternating current lines of a similar length because less power is lost to the air as heat along the way.
Where Innovation Meets the Road | T&D World project was different because it was a transmission-to-transmission application and featured self-contained gas-insulated substation (GIS) bays. This was the first time 230-kV underground cable had been used for temporary work. The rebuild project also involved underground cable connections: GIS to GIS and GIS to air-insulated bus (AIB).
