Radio-frequency high-voltage phenomena

DURING the many years that large amounts of power have been transmitted over long power lines at high voltage, an enormous amount of work has been done on research and development in connection with the high-voltage low-frequency phenomena encountered. In the years that followed, the use of low radio frequencies for communication purposes brought about the need for knowledge of high-voltage phenomena in the region of 100 kilocycles and up to about 200 kilowatts. The men associated with this equipment did a remarkably good job of design on their equipment as may be seen in some of the apparatus still in use, especially in regard to the large antenna insulators used on the long-wave antennas.
