The basics of power quality analysis

Measuring phase unbalance and harmonics at the premises is not enough. You need to know the direction of harmonic power flow. This is very necessary because an installation imports and exports harmonic power. Although not strictly speaking correct, you can simplify the picture as follows; the electricity demand metered is the supplier’s harmonics-distorted voltage multiplied by the installation’s current plus current harmonics. However to really know what’s going on you need measure power with an instrument capable of measuring harmonic phase angles. Going counter-clockwise, angles between 270°(-90°) and + 90° signify imported harmonic power and those going from +90° to 270° constitute exported harmonics.  ... read more
