A domestic or commercial electric appliance (100) is disclosed. The electric appliance comprises at least one electric load (127), an AC power supply input (112) for receiving electric power from an AC power source (115) to be supplied to said at least one electric load, and a current sensor (180) for sensing an AC current absorbed by the electric appliance from the AC power source. The electric appliance further comprises a processing unit (130) for carrying out a harmonic analysis on a sensed AC current sensed by the current sensor and for driving the at least one electric load based on an outcome of said harmonic analysis. 披露了一种家用或商用电器(100)。该电器包括至少一个电负载(127)、用于从AC电源(115)接收要供应到所述至少一个电负载的电力的AC供电源输入(112)、以及用于感测由该电器从该AC电源吸收的AC电流的电流传感器(180)。该电器进一步包括处理单元(130)，其用于对由该电流传感器感测的所感测AC电流进行谐波分析并且基于所述谐波分析的结果来驱动该至少一个电负载。
