Abstract
An ice protection system () comprising electrothermal devices (-) having zones (P-P,L-L,S-S,T-T) associated with respective surface regions of rotor blades. Each zone involves electric load (R) which converts supplied electrical power from one phase of a three-phase power system into heat. The combined load of the A-phase zones, the combined load of the B-phase zones, and the combined load of the C-phase zones are approximately equal.
