Current compensation method and device for current transformer

The invention relates to a current compensation method and device for a current transformer, and the method comprises the steps: detecting the primary current amplitude of the current transformer, and processing the primary current amplitude and a transformation ratio through a preset current compensation model, so as to obtain the real theoretical secondary current amplitude of the current transformer. The secondary current amplitude is an empirical value obtained by learning historical data, and the influence of the primary current amplitude is considered, so that the secondary current amplitude is closer to the real secondary current amplitude, and the detection equipment is not easy to damage when the measuring range of the detection equipment is selected according to the secondary current amplitude. 本发明涉及一种电流互感器电流补偿方法及设备通过检测电流互感器的一次电流幅值，然后采用预设电流补偿模型处理一次电流幅值和变比以获取真正理论上的电流互感器的二次电流幅值，该二次电流幅值为通过对历史数据的学习得到的经验值，由于考虑了一次电流幅值的影响，更接近于真实的二次电流幅值，因此按照该值进行检测设备的量程选择不容易损坏检测设备。
