Abstract

This project is about digital apparent power meter. This meter is used to measure the value of apparent power. Compares to analog system, digital is more accurate and easy to read the measurements as display on the screen. PIC microcontrollers from Microchip were use in this digital apparent power meter project. The main part of this project is encoding and decoding the digital signals. This problem makes it desirable to use a microprocessor, since the data registers can be use to store and parse the digital values at appropriate times. PIC 16F877 A has been chosen as a central processing unit in this project. This digital apparent power meter uses multiple circuits to sense and multiple the values of apparent power and then the signal will be sent to the PIC. Next, the value will be di splay by 7 segments LED display. Using serial port connection as an optional, this meter can be connected to the computer and the value then can be display on the computer. At the end of this project, after implemented the hardware, the troubleshooting is the most important action that must be taken in order to achieve the objective of this project.
