Key Changes and Differences between the New IEEE 519- 2014 Standard and IEEE 519-1992
Written by Ian Wallace, Chief Engineer, Power Quality Solutions, TCI® Technical Paper. Introduction IEEE Std 519-2014 is a newly published revision to the IEEE Recommended Practice and Requirements for Harmonic Control in Electric Power Systems. It supersedes the IEEE Std 519-1992 revision. The overarching goal of the 2014 revision is the same as the 1992Continue reading “Key Changes and Differences between the New IEEE 519- 2014 Standard and IEEE 519-1992”
Knowing IEC 61000-4-30 Class A
Published by Elspec Power quality refers to a set of electrical boundaries defined by various documented rules designed to allow electrical equipment to function in its intended manner without significant loss of performance or life expectancy, this includes the steady and stable supply of electricity delivered by the grid. In order to achieve this aimContinue reading “Knowing IEC 61000-4-30 Class A”
What is Ground Fault Testing, Why is it Important?
Published by Carelabs (Carelabz) A ground fault is any short circuit that outcomes in an unintentional connection amid a ground and energized ungrounded phase conductor and ground. Ground faults are the most common type of fault on power distribution systems. They are due to the insulation failure or accidental grounding of an ungrounded phase conductorContinue reading “What is Ground Fault Testing, Why is it Important?”

Power Quality Standards for Utility Wind and Solar Power Plants
Published by David Mueller, E. H. Camm. Abstract Power quality standards exist to guide the interconnection requirements of large wind and solar plants. IEEE guidelines exist for flicker and harmonics, while IEC guidelines exist for the measurement criteria of power quality phenomena and the characterization of wind turbine equipment. There are also some uniform guidelinesContinue reading “Power Quality Standards for Utility Wind and Solar Power Plants”
