The invention relates to a stray current measuring method and device, equipment and system. The stray current measuring method comprises the following steps: acquiring a power frequency period of an alternating current signal passing through a current carrier to be measured; sampling current signals passing through the current carrier to be detected to obtain a sampling data set of the current signals in the power frequency period, the current signals comprising the alternating current signals and stray current signals, and the sampling data set comprising a preset number of current sampling values; and obtaining a stray current measurement value in the current power frequency period according to the sampling data set. Therefore, the purpose of accurately measuring the stray current on the current carrier to be measured is achieved. 本申请涉及一种杂散电流测量方法及其装置、设备和系统。所述杂散电流测量方法，包括：获取通过待测载流体上交流信号的工频周期；对通过所述待测载流体上的电流信号进行采样处理，以获取一个所述工频周期内的所述电流信号的采样数据集，所述电流信号包括所述交流信号和杂散电流信号，所述采样数据集包括预设数量的电流采样值；根据采样数据集获取当前工频周期内的杂散电流测量值。以达到
