Abstract -The purpose of this paper is the probe and
system will be immediately tripped and which type of fault occurred in system is shown on display.
reveling faults in three phase system. The electric power system is classified in various sections. Transmission system is one of the important system of electric power system, where electric power is transmitted through transmission lines from generating stations to substations and given to consumers. Both methods could occur various types of defects that is called as fault. The fault is defined as” any abnormal condition in the electrical system”. The common faults occur in three phase system is low voltage, high voltage, low current, high current, supply phase fault etc. Due to occurring fault in three phase system, the equipment will be damaged. The benefit of the project is, it not only saves the equipment’s but also it shows the which type of faults occurred in the system. So, it is easy to analyzing the fault.
2.THE OBJECTIVE OF PROJECT
To maintain system stability To reduce the outage time due to faults provide higher level service continuity to customers. Improve the system availability and performance Reduce operating cost save the time required by the crew searching in bad weather, noisy area

1. INTRODUCTION In most of various studies have analyzed that there are so many faults occurs in the three phase systems. These faults such as low voltage, high voltage, low current, high current, low temperature, high temperature, etc. Due to faults occurs in system, the three-phase system will loses their stability and also damages the devices. To overcome these types of faults, we are done this project. This project is working on automatic tripping mechanism. With the help of current sensor and voltage sensor microcontroller-based system is used to analyze and indicate the fault and shows on LED display as well as turn on the LED indicator. The components which are used in system is a Microcontroller, transformer, relay, current sensors, voltage sensors, indicators, 7-segment display.

4. COMPONENTS : 4.1. Transformer
Three phase supply is given to the transformer. the function of transformer is to step down the voltage. And these step down voltage is passes through the voltage sensor and current sensor. Sensors sence the input supply and all data stored in microcontroller, if fault is occurred in system then the
