摘要
介绍了电力系统中有源式电子互感器的工作原理。该互感器以罗柯夫斯基线圈作为电流传感元件,以电容分压器作为电压传感元件,以光纤作为信号传输通道,借助有源电子调制和信号处理技术实现电流、电压的测量。
In this paper,the principle and advantage of ECT and EVT are introduced.A Rogowski coil and a capacitive voltage divider are used as current sensor and voltage sensor respectively in the transducer and optic fibers are used to transmit signal.Active signal modulation and signal processing technology are used too.
