A high power electrical distribution system for distribution high power to at least one consumer arranged on a rotatable element. The distribution system includes at least one high frequency alternating current HFAC generator configured to generate HFAC. A rotary power transformer is connected to the at least one HFAC generator. The rotary power transformer includes a stationary part and a rotatable part and is configured to receive HFAC from the at least one HFAC generator and to couple HFAC electrical energy from the stationary part to the rotatable part. At least one high power distribution bus is located on the rotatable element and is configured to receive HFAC from the rotary power transformer and to distribute HFAC to the at least one consumer.
