Sasaram back-to-back HVDC converter station - Wikipedia station is owned by Power Grid Corporation of India. The converter station consists one pole with a nominal power transmission rating of 500 MW. The converter station was built by Alstom between 1999 and 2002 and has nominal DC voltage and current ratings of 205 kV, 2475 A.  The design is very similar to that of the Chandrapur and Vizag 1 converter stations also built for Power Grid.Country: India
Substation Engineering | AIS and GIS Substations | Beta air insulated substations (AIS) differ from gas insulated substations (GIS) in that the bus and equipment are more susceptible to the elements (temperature, contamination, animals, etc.) and they require much more space to build. However, air insulated substations also offer many advantages.
Rectifier - Wikipedia devices. Before the development of silicon semiconductor rectifiers, vacuum tube thermionic diodes and copper oxide- or selenium-based metal rectifier stacks were used. With the introduction of semiconductor electronics, vacuum tube rectifiers became obsolete, except for some enthusiasts of vacuum tube audio equipment.For power rectification from very low to very high current ...
Electrical Power Transformers - Arrow.com power transformer is a passive electromagnetic device that transfers energy from one circuit to another circuit by means of inductive coupling. Power transformers differ from other transformer types in that they are designed to comply with regulatory requirements for mains power interfacing, working at mains voltages and relatively high currents.
