高电压、大电流到小信号的精确转换是电力保护、测量和控制的关键。传统的基于铁芯的Rogowski线圈通常用于将瞬态大电流转换为小信号。采用印刷电路板（PCB）设计了高精度Rogowski线圈作为传感器。新型PCB传感器用于行波故障检测。提出了两种电路板条结构。详细分析了传感器的特性。提出了一种基于PCB传感器的输电线路故障检测新方法。EMTP仿真和样机测试结果表明，该传感器具有较小的传输延迟，适合于行波故障检测和定位。
An accurate transformation for high voltage and large current to small signals is essential for power protect, measure, and control. Traditional iron-core based Rogowski Coil is usually applied in transforming transient & large currents to small signals. High precision Rogowski Coils are designed as sensors using printed circuit boards (PCB) in the paper. The novel PCB sensor is applied for faults generated traveling waves detection. The two circuit board strips construction is presented. And the sensors' characteristics are analyzed in detail. A new transmission line faults detection method using the PCB sensor is also proposed. EMTP simulation and prototypes test results show that the PCB sensor has less transmission delay and fits to apply in traveling wave based faults detection and location.
