The electrical event that produces the most significant downtime is the transient. A transient is also known as a spike or surge, although, generally these terms refer loosely to the same event. Transients are high energy (with magnitudes in the thousands of volts) and short duration (with rise times in the 1 to 10 microsecond range). Since they are sub-cycle events, they should not be confused with longer duration events such as swells or temporary over-voltages. Click here...

In Part 1 of this informative 2-part read, we began by outlining what power factor is. In Part 2, we discuss power factor correction and how it is performed to achieve a maximum power factor of 1 (unity). The power of unity Power factor correction is performed to restore the power factor as close as possible to unity. This is done with the addition of capacitors to the electrical network. It will compensate for the reacti...

We’re wrapping up our Power Quality series by giving an overview on power factor and the correction of poor power factor. If you missed our previous articles in the series, click below to catch up now!     1. An Introduction to Power Quality     2. Understanding Power Quality issues and what to do about them:         a) Voltage instability...

Over the past few weeks, we’ve discussed facets of Power Quality in our new series. We’re just scratching the surface of Power Quality (PQ) to give you a basic understanding on the aspects that contribute to poor PQ, and what you can do about them: Understanding Power Quality Understanding Power Quality issues and what to do about them: a) Voltage instability...

  In the first article of our new series, we learnt that good power quality saves money and time, ensures a safer workplace, prolonged equipment life and increased efficiency. On the other hand, we also learnt that poor power quality often leads to reduced energy efficiency, and various other downsides. Power Quality has become increasingly prevalent in industry. Power Quality is also such a vast topic that can be discussed at length. We’re just scratching the surface of Power Quality (PQ) to give you a basic unde...

What is power quality, and how important is it? Good power quality saves money and time, ensures a safer workplace, prolonged equipment life and increased efficiency. On the other hand, poor power quality often leads to reduced energy efficiency, and various other downsides. The topic of Power Quality has become increasingly prevalent. Power Quality is also such a vast topic that can be discussed at length. In this series, we’re scratching the surface of Power Quality (PQ) to give you a basic understanding on the aspects that contribute to poor PQ, and what you can do about them: Underst...
