TLDR
In this paper, the authors discuss some of the electromagnetic compatibility issues concerning the use of power lines for communication and conclude that the creation of a low-impedance path by end-user equipment is the main cause of interference.Abstract:
This paper discusses some of the electromagnetic-compatibility issues concerning the use of power lines for communication. Based on a series of measurements performed in a laboratory environment and in the field, five different types of interactions between communication and end-user equipment are distinguished. Measurement examples are shown for several of these types. It is concluded that the creation of a low-impedance path by end-user equipment is the main cause of interference.read more

Power quality issues in the electric power system of the future
Sarah K. Ronnberg,Math Bollen +1 more
TL;DR: In this paper, a shift of resonances to lower frequencies may partially compensate for the increased emissions at higher frequencies, but the transfer of disturbances will become less predictable and equipment immunity also becomes less predictable.

Limits for Voltage Distortion in the Frequency Range 2 to 9 kHz
TL;DR: In this article, the authors considered voltage distortion in the frequency range 2 to 9 kHz, above what is normally considered in harmonic studies, and concluded that 0.5% of nominal voltage per 200-Hz band is a safe limit.
