Patil ME (ETX) Student, Dr.J.J.Magdum College of Engineering, Jaysingpur, Dist.-Kolhapur, State- Maharashtra smitawale@yahoo.co.in Abstract Power systems are important and expensive components in the electric power system. The knowledge of the actual status of the system insulation behavior, load tap changer performance, temperature, and load condition is necessary in order to evaluate the service performance concerning reliability, availability and safety. Systems abnormalities, loading, switching and ambient condition normally contribute towards accelerated aging and sudden failure. The paper presents the causes which lead to the internal faults appearance in the power system. The production mechanisms of the faults and the on-line monitoring are also analyzed. A monitoring procedure is proposed for the diagnosis and forecasting strategy of the functioning state of the power system.

INTRODUCTION A Supervisory Control and Data Acquisition system has been developed with an auto fault detection capability.[1] The Programmable Logic Controller used in a standard Supervisory Control and Data Acquisition system has been eliminated by using a microcontroller, resulting in a lower cost. Signals derived from a large number of detectors and sensors can be processed simultaneously.[2][3] The design enables the system to check the alarm status, true or false i.e. normal, faulty sensor, or open circuit. The data acquisition circuit is interfaced with the microcontroller board to evaluate the current flow conditions, normal or abnormal. A program written in Visual Basic provides for a graphical layout of the plan of the plant or building to be displayed on the monitor with a clear indication of the alarm spot.[1] A Close Circuit Television camera is made to move automatically to capture the particular location of the triggered alarm at the same time of the alarm signal. The methodological framework for managing Supervisory Control and Data Acquisition systems with auto fault detection using microcontroller constitutes the major contribution of the this.[2] The power-line communications has been applied as a data transfer method in mechanical system and indoor distribution networks.[3] The characteristics of power-line channels and the applicability of different digital modulation techniques have been widely researched. Fault detection in mechanical system is an important element for industrial growth & social development. For the last fifty years, electric power system has rapidly grown. This has resulted in large increase of the number of lines in operation & their total length. These lines experience faults which are caused by insulation breakdown & short circuits, sudden outage of line etc.[3][4] The purpose of this project is to acquire to remote electrical parameters and send these real time values over Global System for Mobile Communication using Global System for Mobile Communication modem/phone.[1] The project is also design to protect the electrical circuitry by operating electromagnetic relay this relay gets activated whenever the electrical parameter exceed the predefined values, the relay can be used to operate the circuit breaker to switch off the main electrical supply.[2] User can send commands in the form of SMS messages to read the remote electrical parameters. The system also can automatically send the real time electrical parameters periodically based on time setting in the form of SMS.[3] This also can be design to send SMS alerts whenever the circuit breakers trips or whenever the voltage and currents exceeds the predefined limits.[4] 2.
