In turn, this geoelectric field creates what are known as geomagnetically induced currents, or GICs, which flow in any available conductor, including high-voltage transmission lines, oil and gas pipelines, railways, and undersea In the United States, the extra-high-voltage (EHV) portion of the power grid has grown by a factor of 10 [PDF] since the late 1950s. An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. The major challenge in UHV power engineering is to provide sufficient insulation to prevent voltage flashovers. 69 kV, 115 kV, 138 kV, 161 kV, 230 kV. Other key products delivered include thyristor valves, DC and AC (direct and alternating current) switchyard equipment and the newly developed DCC800 HVDC control system. Direct-current high voltage (dc HV). ABB was the main technology supplier to State Grid Corporation with ABB components and technology, in local partnership. We engineers have presided over this growth and can feel justifiably proud of what it has brought society. So, Sub-Stations are important part of power . Engineering Electromagnetics Tewari J P. Transmission at such high voltages reduces power losses and is therefore more efficient. ABB has commissioned the Xiangjiaba-Shanghai project, the world's first UHVDC (ultrahigh-voltage direct current) transmission link to go into commercial operation.
