Project Summary

The most important purpose of this system is monitoring and controlling of transformer.The differential relay can detect internal faults easily.The principle of Differential Protection scheme is simplistic conceptual technique.The differential relay actually distinguishes between primary current and secondary current of the power transformer if any unbalance noticed in between primary and secondary currents the relay will actuate and trip both the primary and secondary circuit breaker of the transformer. Differential protection is based on balancing current on both sides of the winding.As per classical method, primary and secondary phase current are measured, converted to common base value and compared to compute differences in the currents.Under the normal operating condition fault current is small and in the abnormal condition,it becomes too high so that can be detected by the relay.However, they achieve a larger value during the internal faults,which recognizes them as the detection parameters for winding inter-turn fault.However, the sensitivity of this method for winding-failure detection depends largely on the accuracy of measurements by the instruments transformer.

Project Objectives

• Self-protection in the case of overload on the transformer and the separation of the full and inform the maintenance teams.
• Detect of the faults in real time base on current,voltage and temperature.
• Increase system reliability and stability by the monitoring system.
• The system prevents faults and losses of the power supply which significantly benefits utility consumers.

Project Implementation Method

This project is implement in heavy load conditions,manufacturing.Where we use power transformer to stable our system and to protect our load

Benefits of the Project

• Using Differential protection scheme, transformer is protected from faults with the use of raspberry pi operating an electromagnetic relay.
• The protection schemes so far designed can successfully protect the transformer and mitigate the risk of enormous destruction.
• The benefit of this methods is,it is an automatic protection method no manual work is required.

Technical Details of Final Deliverable

In this project we use power transformer for controlling system and use Current Transformer for measuring current and also we use differential relay,overload relay for loads and magnetic contactor for the transformerthe magnetic contactor connects with realay and to trip the circuit breaker if load exceeds from the limits.In this project we use Raspberry pi with sensors to display our voltage,current and temperature on LCD screen.he GPRs system is used to see the data on mobile.
