Abstract :
The authors discuss the design and realizations of a broadband network and its application to a voltage probe for monitoring the disturbance on the AC power line, including the very low-frequency components above the fundamental 50- or 60-Hz frequency. The circuit is capable of monitoring frequencies from a few hundred hertz to well beyond 200 MHz. The very large bandwidth is obtained by paralleling the basic step-skirt high-pass filter structure with a high-frequency pass-over branch. The basic characteristics such as inband attenuation, power-frequency rejection, impedance, and dimensions compare satisfactorily with existing voltage probes having much larger low-frequency cutoff
