Extra High Voltage A.C. Transmission Engineering R.D. Begamudre
Publisher: New Age Publications (Academic)

Electric Locomotive Electrical & Electromagnetic interferance. In electric power transmission engineering, high voltage is usually considered any voltage over approximately 35,000 volts. Ultra High Voltage (1000 kV; UHV) AC transmission technology is the most advanced AC transmission mode with the highest voltage until now. 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.

In such a situation the transmission substation contains high voltage switches that allow lines to be isolated or connected for maintenance or fault clearance. New breaker at world`s highest AC voltage level can reduce footprint up to 60 percent. Effect on generating units caused by loss of excitation. ABB to develop 1,200 kilovolt ultra high-voltage circuit breaker. 24570 This book written by begamudre is almost clearly explains the ehv ac transmission and this is a part of M.E/M.Tech Power systems/HighVoltage Engineering. Extra-high voltage (EHV) ac: 345 kV, 500 kV, 765 kV.
