Published by Arbiter Systems, Inc. Enabling Tomorrow’s Technology Today Overview As regulatory authorities impose ever-stricter requirements for power quality, utilities increasingly want to know which customer is imposing harmonics and flicker on the utilities power system. As a result, we are often asked if we can determine the “direction” of harmonic power flow, and whatContinue reading “Direction of Harmonics & Flicker”
