Can neutral currents, such as the 3rd harmonic, be reduced by the use of 3rd harmonic blocking filters?

Published by Mirus International Inc., [2010-01-08] MIRUS-FAQ001-B2, FAQ’s Harmonic Mitigating Transformers, 31 Sun Pac Blvd., Brampton, Ontario, Canada. L6S 5P6. Some manufacturers are promoting the use of 3rd harmonic (180 Hz) blocking filters for the treatment of high neutral currents caused by non-linear loads such as personal computers. These devices are parallel L-C filters tunedContinue reading “Can neutral currents, such as the 3rd harmonic, be reduced by the use of 3rd harmonic blocking filters?”

What is a DSO?

Published by European Distribution System Operators (E.DSO), Why smart grids?Website: edsoforsmartgrids.eu Distribution system operators (DSOs) are the operating managers (and sometimes owners) of energy distribution networks, operating at low, medium and, in some member states, high voltage levels (LV, MV). Transmission grids transport large quantities of high (and extreme high) voltage (HV, EHV) electricity across vastContinue reading “What is a DSO?”

General Reference – Wiring and Grounding

Published by Electrotek Concepts, Inc., PQSoft Case Study: General Reference – Wiring and Grounding, Document ID: PQS0609, Date: July 1, 2006. Abstract: Wiring and grounding problems are responsible for many power quality variations within customer facilities. Some electric utility engineers have estimated that 80% of all the power quality problems reported by customers are found toContinue reading “General Reference – Wiring and Grounding”

Am I not safe from harmonics if I use K-Rated transformers and oversized neutrals?

Published by Mirus International Inc., [2010-01-08] MIRUS-FAQ001-B2, FAQ’s Harmonic Mitigating Transformers, 31 Sun Pac Blvd., Brampton, Ontario, Canada. L6S 5P6. K-Rated transformers made their appearance several years ago as a means of preventing transformers from failing when subjected to heavy non-linear loading. They are essentially ‘beefed up’ transformers with extra steel in their cores andContinue reading “Am I not safe from harmonics if I use K-Rated transformers and oversized neutrals?”

Why is Good Power Quality Necessary?

Published by Merus Power Plc., October 13, 2016 Power quality is commonly defined as the power grid’s ability to supply a clean and stable power flow as a constantly available power supply. The power flow should have a pure sinusoidal wave form and it should remain within specified voltage and frequency tolerances. Why is goodContinue reading “Why is Good Power Quality Necessary?”
