摘要：A method and a device for managing electric network non-power frequency separate the electric network non-power frequency based on the sum of three-phase voltage or current from the electric system by use of a transformer or a current transformer (XBYQ). The electric network non-power frequency energy is consumed by the secondary circuit formed by impedance (R) arranged in the secondary side of the transformer or the current transformer (XBYQ). Alternatively, the electric network non-power frequency signal is inverted at the secondary side of the transformer or the current transformer, then the inverted signal is fed back to the electric system via the primary side of the transformer or the current transformer to cancel out the electric network non-power frequency. The electric network non-power frequency is three-phase asymmetric. A symmetric electric network non-power frequency releasing path is provided in one phase or two phases and arranged at the primary side of the system or at the secondary side of the transformer or the current transformer (XBYQ), so that the three-phase symmetric electric network non-power frequency is converted into three-phase asymmetric electric network non-power frequency.
