History Of

Traditional methods to measure power system harmonics employ either a power harmonic analyser or a software package such as Matlab. However, these usually have limited capability when used with an Internet connection and/or graphical interface. In this paper, a PC-based virtual instrument (VI) that can carry out remote measurement and monitoring using LabVIEW and a microprocessor (Intel 8051) for power system harmonics is proposed. The history of total harmonic distortion (THD) in the waveform signal can be also recorded and tracked in the database.
