Abstract :
Conductors, energized at the world´s highest voltage, are aglow with corona at General Electric´s Project EHV. Corona, a discharge of electricity, is emitted because the three single conductors are arranged for a transmission of 460,000 volts, but are being energized at the new world high of approximately three-quarters of a million volts. Conductors coming into the transmission tower from upper right are without corona because they are bundled in groups of four — the proper arrangement for transmissions up to 750,000 volts. Later, all conductors will be arranged in this manner.
