PQ Analysis: Flicker, Transients and Noise

Published by testguy, November 23, 2019. Website: testguy.net Flicker, Transients and Noise Repetitive voltage reductions in lighting circuits can be detected by the human eye, a phenomena known as “flicker.” The term flicker refers to a very specific problem related to human perception of light produced by incandescent light bulbs, not necessarily general voltage fluctuations. Some commonContinue reading “PQ Analysis: Flicker, Transients and Noise”

Fluke 43B PQ Analyzer – Receptacle Branch Circuits

Applications Guide, April 2001 Published by Fluke Corporation Troubleshooting Electrical Distribution Systems The most efficient way to troubleshoot electrical systems, is to begin at the load and work towards the building’s service entrance. Measurements are taken along the way to isolate faulty components or loads. This chapter describes typical measurements for troubleshooting problems on receptacleContinue reading “Fluke 43B PQ Analyzer – Receptacle Branch Circuits”
