PDZ800 Series Intelligent Distribution Terminal

Distribution Terminal is an important component of distribution automation. It is a general term for all types of devices installed in medium voltage distribution network and used for remote monitoring and control. Distribution terminals mainly include Distribution Terminal Unit (DTU), Feeder Terminal Unit (FTU), Transformer Terminal Unit (TTU), etc.

PDZ800 series intelligent distribution terminalssuit the situation of distribution automation system of China and can meet the actual needs of distribution grid transformation in both urban and rural areas. Distribution terminals adopt distributed and modularized design and are equipped with highly reliable measuring and control lines and high speed bus network with strong anti-interference capability. PDZ800 series distribution terminals are able to comprehensively analyze the data acquisition and control that are important for distribution grid operation. Based on the analysis, they then monitor in real-time all primary equipment including 10kv switching station of ring network, ring main unit, distribution transformation, and capacitor etc. PDZ800 series intelligent distribution terminals are easy to install, debug, and expand and are highly expansible, reliable and accurate in measurement.
