Most of us clearly understand power outages and can easily recognize that not having power will impact your business. However, power outages are relatively rare because of technological advances and the grid’s design. What’s less understood are the more common short-term events, which typically last less than a second, but can [...]

Modern electrical installations supply power to a wide variety of non-linear loads, where the current drawn does not have a linear relationship with the voltage supplied. In other words, even if the supply voltage signal is a perfect sinewave when measured with an oscilloscope, the resulting current may have a [...]

Harmonics in an electrical system/equipment occur due to fluctuations in the current or voltage. The propagation of harmonic frequencies is one of the most important cause of power quality problem in the electrical systems. Harmonic causes torque fluctuations, misfiring in variable speed drives and heating in the system. Thus, in [...]

Power quality and harmonics have been a developing and growing concern as buildings have become more reliant on technology, the ever-increasing utilisation of digital control systems, and the drive towards more efficiency.  In recent years, harmonics from buildings have caused issues to supply networks, and authorities now require owners of [...]
