Abstract
High-frequency AC voltage with a frequency in a range of from 60 to 100 kHz supplied from a power source at 3 to 15 kV is applied to an electrical conductor within about 30 cm of a cableway. The high-frequency AC voltage generates an alternating electric field. Capacitive AC current associated with the alternating electric field flows through the ice on the cableway and on the electrical conductor, causing dielectric loss heat that melts the ice.
