Design of Digital Fault Recorder Using Microcontroller for Electrical Distribution Company Network

Abstract

It is obvious that our modern life has become very dependent on the constant availability of electricity. Therefore, the efficiency of electrical energy is of the utmost importance in our lives and this increase in the sensitivity of electrical appliances used both on the domestic and practical side. This efficiency is achieved consistently values of voltage, current, frequency, and any turbulent changes in the values of these elements may cause damage to users. The thesis aims to monitor the main electrical elements continuously and record mistakes if they occur and then send these data to the specialized control center so that operators can analyze the situation and take appropriate measures to reduce the effects of these errors on the electrical grid and users. The exact controller is used as the controlled mind of this system. The readings of the current values of the current network are taken from the current transformers with the main switches and then sent directly to a computer in the control center and received and displayed using a specific programs.
