DLC channel noise characteristics : a survey of measurements

Knowledge of characteristics of electrical noise in power distribution networks between 2kHz to 150kHz is essential for optimum Distribution Line Carrier (DLC) system design. Reported findings on noise measurements in MV and LV networks in North America and Europe.. Knowledge of the characteristics of electrical noise in the power distribution network's between 2kHz to 150kHz is essential for optimum DLC system design. The available literature is surveyed to identify noise characteristics of typical DLC channels. Reported measurements to date indicate the DLC noise predominantly originates from customer's loads and is a mix of two or more noise processes. It is typically nonstationary and impulsive in nature.
