Power harmonics management – Harmonics standards Harmonic emissions are subject to various standards and regulations: • Compatibility standards for distribution networks• Emissions standards applying to the equipment causing harmonics• Recommendations issued by Utilities and applicable to installations In view of rapidly attenuating the effects of harmonics, a tripleContinue reading “Harmonics Standards”

Billing Measurements in the High and Extra-High Voltage Network taking into Account the New Frequency Classes According to IEC 61869-1 ED2 (AFDIS)

Published by Roland Buerger (Senseleq B.V.), Dr. Thomas Heid (CONDIS SA) Internationally, it is not easy to specify the range of high voltage exactly. The boundary between medium and high voltage is between 30 kV and 100 kV, depending on local and historical conditions. In the current version of EN 50160 from 2020, the voltageContinue reading “Billing Measurements in the High and Extra-High Voltage Network taking into Account the New Frequency Classes According to IEC 61869-1 ED2 (AFDIS)”

Arc Flash and Overvoltage Protection

Published by Alex Roderick, EE Power – Technical Articles: Arc Flash and Overvoltage Protection, August 26, 2021. In addition to the risk of electrical shock, other hazards are present when work is performed on or near energized electrical equipment or conductors. Two serious hazards are electrical arc flashes and electrical arc blasts. An arc flash isContinue reading “Arc Flash and Overvoltage Protection”

The Difference Between Class A & Class S

Published by GMC-Instruments Power Quality: What Does Class A Mean? Power quality monitoring doesn’t often become an issue until incidents such as system malfunctions, equipment failures, process interruptions, data loss, IT disruptions or even power failure have occurred. As a rule, incidents of this sort are very time-consuming because they cause can’t always pinpointed rightContinue reading “The Difference Between Class A & Class S”
