HVDC
High Voltage Direct Current transmission involves transmitting Voltage at a very high value of DC, 500 kV instead of adopting AC, thus reducing skin losses, which constitutes a major part of the losses in a transmission line. HVDC, due to its many advantages is emerging as a choice to the Conventional AC transmission. HVDC was [...]
