The main aim of the project is to design an industrial fencing security implementation system using SCADA along with three phase fault detection system. The system also detects and alerts the user through SMS messages using GSM modem. In this system, measuring of industrial parameters such as voltage, current, temperature, frequency and then data are transferred to the SCADA central host controller(PIC16F877A) .And the system detects the earth fault and 3-phase fault which is inter faced to the SCADA central host microcontroller. And also, the system alerts when human presence detected using IR sensor near the fencing area. If any parameters value exceed threshold value or else system detects the 3-phase fault or else if the IR sensor detects the person, then the system automatically breaks the circuitry using Relay and it sends the relevant alert messages to the predefined mobile number through GSM modem. We get both audible and visual alerts using LCD and Buzzer. The monitoring statuses about the parameters along with detection of different faults are displayed onto the LCD module. Here relay works as Supervisory Control to break the circuit. This project is also designed to protect the electrical circuitry by operating an Electromagnetic Relay.  This Relay gets activated whenever the electrical parameters exceed the predefined values.  The Relay can be used to operate a Circuit Breaker to switch off the main electrical supply. Here relay works as Supervisory Control to break the circuit. This project makes use of an onboard computer, which is commonly termed as micro controller. It acts as heart of the project. This onboard computer can efficiently communicate with the output and input modules which are being used. The controller is provided with some internal memory to hold the code. This memory is used to dump some set of assembly instructions into the controller. And the functioning of the controller is dependent on these assembly instructions.    

The objectives of the project include:

1. Sensing different electrical parameters (voltage, current, temperature, frequency).
2. Sensing three phase faults.
3. Using GSM technology to send the alert message.
