Measurement of powerlines and devices using an inductive shunt on-line impedance analyzer

Abstract

This paper describes an Inductive Shunt PLC coupler, for coupling wideband PLC signals onto power lines with high efficiency and low distortion and shows how this can be used for measuring PLC frequency impedances of power lines, distribution transformers, motors or any other appliance. The paper presents some impedance measurements of power lines, appliances and distribution transformers.
