The invention discloses a method and a device for checking the transformation ratio of a current transformer in an uninterruptible operation site, and the method comprises the steps: collecting the current through a high-low voltage current transformer, forming a digital signal through an AC collector, and transmitting the data of the digital signal to a server through a wireless technology; actual data on the electricity meter are obtained, the actual data are compared with the collected data to form complete data, the complete data are displayed on an interface through software, and therefore whether a user replaces an original current transformer or not can be effectively monitored to reduce electricity consumption, and the purpose of electricity stealing is achieved. 本发明公开了一种不停电作业现场电流互感器变比校验方法及装置，采用高低压电流互感器对电流进行采集，通过交流电流采集器形成数字信号，将数字信号通过无线技术把数据远传上服务器；获取电表上的实际数据，将实际数据与采集数据进行对比形成完整数据，再通过软件展示在界面上，从而可以有效监测用户是否更换原有电流互感器来减少用电量从而达到窃电目的。
