Measurement and Analysis of Low-Voltage Power Carrier Characteristics *

Abstract

This paper introduces a measurement method of the transmission characteristics of the low-voltage power line channel to effectively evaluate the influence of the power consumption environment in the low-voltage distribution station area on the power line carrier signal. the experimental results show that the characteristics of high and stable impedance and low noise level appear at the voltage zero-crossing point, which is suitable for signal transmission and is beneficial for system time synchronization.
