Design and Construction of Digital Line Frequency Meter using PIC Microcontroller
Shagun Malhotra, Twishish Shrimali, Abhishek Verma
Abstract: In power transmission system, the line frequency matching from one end to another forms a very critical part of matching parameters at the receiving end. It can lead to serious implications if accuracy is not taken into account. Therefore the accuracy for line frequency measurement plays a major role in the power line transmission system. This paper describes a very simple and compact design of Digital Line Frequency Meter using PIC microcontroller. This line frequency meter having frequency measurement range from 10.00 Hz to 90.00 Hz, with a resolution of 0.01 Hz and accuracy 1 %. Digital line frequency meter is a 4 digit type of digital meter, the usage of latest CMOS IC technology has helped in increasing the reliability, accuracy and making the unit light weight and compact.
