Method for deicing energized electrical transmission lines

A method of de-icing energized electric lines of an alternating current voltage distribution or transmission network comprising the steps of:

• providing an apparatus capable of producing an adjustable angular offset between voltages at its terminals;
• selecting segments of the energized electrical lines to be de-iced;
• connecting the segments to form a loop by selectivly operating circuit breakers of the network;
• connecting the apparatus in series with the segments of the loop to be de-iced;
• activating the apparatus;
• adjusting the angular offset of the apparatus to impose an increase in current flowing in at least one of the segments of the loop, thus causing the de-icing of said at least one of the segments of the loop;
• adjusting an internal angle of the apparatus to a value of zeroes;
• operating a circuit breaker connected between the segments of the loop in a closed position to short-circuit the apparatus;
• operating a line circuit breaker on one of the segments of the loop into an open position for concentrating a charging current in the other segment of the loop;
• and
• operating the circuit breaker connected between the segments of the loop in an open position.
