HVDC transformers can have different configurations, such as single-phase, three-phase, or twelve-phase. They can also have different winding connections, such as star-star, star-delta, or delta-delta. The choice of configuration and connection depends on the type and topology of the HVDC syst...
transmitted at a higher voltage, and distributed at a lower voltage again. This voltage variation is for many technical and economic reasons. For changing this voltage at many locations in the power system, an arrangement of various electrical equipment is used which is known as asubstation. ...
Although HVDC transmission has exploited line-commutated power electronics for the past three decades, it is the 1990s which have witnessed the commissioning of self- commutated power electronics at the transmission level. Developments in semiconductors and their packaging technology will drive power ...
The DC circuit breakers which comprises of mechanical, solid-state and hybrid breakers are mostly applied in domestic and industrial applications that employ the use of direct current (DC) especially in high voltage direct current (HVDC) network system for the protection of electrical devices. AC ...
In a high voltage system, the surge diverter can be used to defend the transformers, lines, circuit breakers,generators, bus bars,circuit breakers,etc. The arrester like HVDC system is mainly used for protecting the filter, unit reactor, buses, ...
