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”

PQ Monitoring Standards – What You Need To Know

DESCRIPTION There’s an age-old problem in the Power Quality (PQ) monitoring industry – measure the same circuit with instruments from different manufactures at the same time, and you could get different results! Which one do you believe? Do you trust any of them? There have been electrical energy monitoring standards for many years that defineContinue reading “PQ Monitoring Standards – What You Need To Know”

Voltage Tolerance Boundary

Published by Pacific Gas and Electric Company (PG&E), January 1999. The only national standard for utilization voltage regulation is ANSI C84.1. Its title is American National Standard for Electric Power Systems and Equipment – Voltage Ratings (60 Hertz). The first version in 1954 was a combination of two standards, one from the Edison Electric InstituteContinue reading “Voltage Tolerance Boundary”
