  • UHV Transmission Technology | ScienceDirect

    Abstract. In terms of overvoltage and insulation coordination, a UHV system is similar to an extra-high-voltage (EHV) system. However, as UHV system lines are characterized by a larger transmission capacity, longer transmission distances, and large reactive power (the reactive power per 100 km of 1000-kV lines reaches up to about 530 Mvar) such that: (1) load rejection may cause serious
