    • An electronic filter for filtering the output signal of a current sensor of a circuit breaker is disclosed. The current sensor has an output signal characteristic similar to that of a Rogowski coil output signal characteristic that includes a third harmonic noise component in response to a switching primary current of the circuit breaker, and the circuit breaker has an electronic trip unit with an instantaneous pick-up setting responsive to the output signal of the current sensor. The electronic filter includes a first stage and a second stage. The first stage has a first transfer function that defines first characteristic poles and permits passage of the third harmonic noise component. The second stage has a second transfer function that defines second characteristic poles and filters the third harmonic noise component.
    • 公开了一种用于对断路器的电流传感器的输出信号进行滤波的电子滤波器。 电流传感器具有类似于罗氏线圈输出信号特性的输出信号特征,该特性包括响应于断路器的开关初级电流的三次谐波噪声分量,并且断路器具有具有瞬时拾取的电子跳闸单元 - 响应于电流传感器的输出信号的设置。 电子滤波器包括第一级和第二级。 第一级具有第一传递函数,其定义第一特征极并允许三次谐波噪声分量的通过。 第二级具有第二传递函数,其定义第二特征极并对三次谐波噪声分量进行滤波。
