Low Voltage - upto 1000V Medium Voltage - 1000V to 35kV. €Half of the population in the United States lives within 100 miles of the coasts, but most of the wind resources lie between North Dakota and West Texas,” says Michael Heyeck, senior vice president for transmission at the utility giant American Electric Power. 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. AC voltages have been classified in various manners. In some situations, the term Ultra High Voltage is used to denote voltages above 800 kV. SUBJECT NAME: EHV POWER TRANSMISSION. New breaker at world`s highest AC voltage level can reduce footprint up to 60 percent. POWER SYSTEM ENGINEERING PS 9223/236207/PS 923 — FLEXIBLE AC TRANSMISSION S.. Electrotechnik - The Website on Electrical Engineering · Home LV, MV and EHV. In addition, the IEC defines a voltage band known as the Extra Low Voltage with a AC voltage less than 70 V. In electric power transmission engineering, high voltage is usually considered any voltage over approximately 35,000 volts. ABB to develop 1,200 kilovolt ultra high-voltage circuit breaker. When electricity leaves a power plant today, it is shuttled from place to place over high-voltage lines, those cables on steel pylons that cut across landscapes and run virtually contiguously from coast to coast. Extra High Voltage - above 230 kV.
