Harmographic Analysis

Power Quality Expert have developed harmographic analysis to innovate and enhance the traditional analysis of electrical harmonics. Harmographic analysis produces a unique visual “heat map” representation of an electrical systems harmonic profile. The harmographic map of the electrical harmonics is produced using our unique harmographic analysis algorithm which is used to process the traditional fast Fourier transform (FFT) measurements made by a power quality analyser.


The harmography technique can also be employed to process groups of harmonics or individual harmonic frequencies to produce a harmographic image specific to different types of connected loads or to visualise supply side harmonic compliance with unique visualisations of the harmonic components present in an electrical system.
