TRANSMISSION LINE MULTIPLE FAULT DETECTION AND INDICATION TO EB
Introduction

 Detect faults in remote transmission lines
 Immediately transmit any fault information to the Electricity board.
 Monitor multiple parameters such as voltage, current and temperature simultaneously
 Transfer data through a wireless medium such as Zigbee.
Features
 No wires involved
 Can detect faults due to over current, under voltage, increased temperature etc.,.
 Can operate in any environment in a transmission line.
 Can monitor multiple transmission lines sitting in an office.
 Block Diagram
VOLTAGE SENSING
 Voltage (potential) transformer steps down the voltage in the transmission line.
 It is converted into a dc voltage after rectifier and filter.
 This rectified dc voltage gives a proportional voltage of the transmission line.
 It is fed into the ADC of the microcontroller.
 This ADC value gives the voltage present in the transmission line.
CURRENT SENSING
 Current transformer senses current taken by the load in a transmission line
 The interfacing circuit converts ac current into ac voltage and converts into dc voltage.
 The DC voltage is then given to ADC inside microcontroller which calculates the exact current flowing through the line
 Depending upon the ADC value the microcontroller finds current in the transmission line.
Temperature Sensing
 LM35 is used for temperature sensing
 It is a linear centigrade sensor.
 The output voltage is given by 10mV/C
 Can measure temperatures upto 150’C
 Accuracy is within 0.5’C
 Integrated sensor in a simple 3pin package.
Block Diagram
Microcontroller

 PIC16F877A is the microcontroller used in the project.
 The controller has peripheral features like inbuilt ADC, required to get the signals from the sensors.
 Maximum clock frequency is 20MHz and hence faster than 8051.
 Based on RISC and Harvard architecture and hence even more faster.
 Embedded C is used for programming the microcontroller.
Voltage Conversion
 Is required because of the mismatch in the operating voltages for Xbee and microcontroller.
 Microcontroller operates at 5V and Xbee operates at 3.3V.
 Hence direct communication between the two is not possible.
 Voltage conversion reduces the voltage from 5V to 3.3V when microcontroller is transmitting.
 It increases the voltage from 3.3V to 5V when the Xbee is transmitting.
 It is also used in the control room module for the same purpose.
PC Application
 A PC is used to monitor the contactor status and the load status.
 On the PC a visual basic program will be used.
 VB is used because it offers a easy to use and program graphical interface.
 The PC displays all the values and also indicates to the user if there is any fault or not.
Hardware Components
 PIC 16F877A microcontroller
 Sensors
 Zigbee transceiver
 Max232 for PC interface
 PC
Software Tools
 MP Lab IDE for PIC programming
 Orcad 16 for schematic design
 Eagle layout Editor for PCB design
 Visual Basic for PC programming in EB office
