Voltage Disturbances Flicker Measurement
Published by Zbigniew Hanzelka & Andrzej Bie´n, AGH University of Science and Technology, October 2005 Flicker Measurement Introduction The power supply network voltage varies over time due to perturbations that occur in the processes of electricity generation, transmission, and distribution. Interaction of electrical loads with the network causes further deterioration of the electrical power quality.Continue reading “Voltage Disturbances Flicker Measurement”
Direction of Harmonics & Flicker
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”
