Abstarct: Power distribution posts are responsible for has a task of distribution consuming electrical energy to subscribers’ domestic, commercial, industrial and etc. Considering the number and the power of subscribers which fed by the power station, power and number of output lines can be specified posts. Eachpower distribution postcouldhave one input line and minimum 1 to 14 low pressure output. Each line consists of three phases and a null. The most important parameters (data) per line are, including: voltage (V), electric current (A), power factor (cosφ) and the harmonic voltage and current waveforms.
Engineers design and operation of electricity distribution networks, to design and optimize utilization of the network, always require that all parameters of the power distribution posts have provided. By using two methods manually and automatically can be gathered the necessary information. Manually method is time-consuming and has error with the high executive cost. In the second approach with systems installed in all existing posts, information collected and will be sent to the central station. In addition to seeing the center and store data for other purposes, they can be process and the necessary information to be extracted.
In line with this objective, a system has been designed and installed in which is able to read all the information after every post and to collect and maintain them. Stored information can be, under software which is provided for data processing, such as a curve in the timefrxame show. System built is include 15 input current line and input voltage line. Implementing this system in the industry as one of the country's electricity distribution companies, can be claimed that the automation system and monitoring low pressure power distribution posts with specific profile we have implemented and executed.
