Scalable System with Rogowski Coil for E-management of Detection and Measurement of PLC Interference in Electric Power Grids

The article presents the structure, principle of operation and measurement properties of the developed control system intended for e-management of detection and measurement of disturbances in the low-frequency bandwidth of the PLC (3 kHz-148 kHz). As a detector, Rogowski's coil made in high-density printed technology (PCB HDI) was used. The results of testing the parameters of both particular components and the completed system in transient as well as in steady state are presented. Based on the obtained measurement results, appropriate practical conclusions are formulated.
