Impulse Noise Considerations Related to Data Transmission over High-voltage Lines

Abstract

This paper describes methods for theoretical modeling of inter-arrival time of impulse noise and presents a new model based on the application of general mathematical distributions, together with its implementation in MATLAB. It also discusses the suitability of this model for development and testing of digital communication systems intended for deployment on high-voltage power distribution lines.

Environmental Detection of Clandestine Nuclear Weapon Programs

“…This creates step-function artifacts in the current draw, called line notches, which result in wideband back-EMF noise on the line (Jarc & Schieman 1985). Propagation of this noise can be modeled using the telegrapher's equations (Krejci et al 2014). A calculation shows that characteristic frequencies in the Fourier decomposition may travel along typical power lines for many hundreds of miles if not filtered by a power substation.…”

Electromagnetic compatibility of PLC adapters for in-home/domestic networks

“…Video communication and other similar services are especially sensitive to impulse noise, because these services require operations in real-time and they also need a high level of reliability. Although recent standards [25,27,28,30] require uninterrupted normal operation of these devices with constantly emitted electromagnetic radiation (contains impulse noise too) [1][2][3][4]. There can occur some cases when the operation of these devices is interrupted or failed [1].…”

The use of programable logic controllers (PLC) technology in electrical networks 230 V causes electromagnetic radiation that interferes with other electrical equipment connected to the network [1][2][3][4]. Therefore, this article describes the issues of electromagnetic compatibility (EMC) of new PLC adapters used in IP broadband services in a multi-user environment.
