Ultra-high voltages increase the capacity of power cables, thereby making it possible to transport large amounts of electricity with a relatively small number of overhead lines. Compared with high-voltage alternating current (AC) grids, active power conduction losses are relatively low and reactive power conduction losses are zero in an HVDC grid. In electric power transmission engineering, high voltage is usually considered any voltage over approximately 35,000 volts. Allan Greenwood, 'Electrical Transients in Power Systems', Wiley Interscience, New York, 2nd edition 1991. The selection and performance of insulated cables in electrical grids is a vital part of electric power transmission, but is often neglected in favour of a focus on technological construction. EHV AC Undergrounding Electrical Power It will enable readers to make detailed performance comparisons between power transmission systems, which will be valuable for postgraduates, as well as engineers involved in power cable manufacturing or electrical transmission systems. R.D.Begamudre, 'Extra High Voltage AC Transmission Engineering', Wiley Eastern Limited, 1986. The new circuit breaker has been designed for a 1.2-megavolt AC transmission line. Electrical Engineering · Power Substations The advance of voltage source converter-based (VSC) high-voltage direct current (HVDC) transmission systems makes it possible to build an HVDC grid with many terminals. This is a classification based on the design of define high voltage circuits as those with more than 1000 V for alternating current and at least 1500 V for direct current, and distinguish it from low voltage (50–1000 V AC or 120–1500 V DC) and extra-low voltage (<50 V AC or <120 V DC) circuits.
