Measures to reduce interference from Variable Speed Drives
Often referred to as Variable Frequency Drives, AC Variable Speed Drives (VSD) generate a great deal of electrical interference. Pulse Width Modulation (PWM) is the standard method for controlling motor speed in VSDs. The quick rise and fall times of… Read more

Practical design knowledge in harmonics distortion and power factor correction (PFC)
Nowadays, if you do not consider harmonics distortion when designing a new network, you missed the whole point of the network design. Yes, really. The sooner you realize that harmonics problems are on the rise, the better. Modern power networks… Read more

The magic that isolation transformer uses to suppress transients and noise
Transformers are not perfect. Transients and noise (radio-frequency and low-level spikes) normally pass through transformers, not only by way of the magnetic lines of flux between the primary and the secondary windings but through resistive and capacitive paths between the… Read more

Six methods to control the flow of harmonic currents and decrease harmonic distortion limits
The first technique to control harmonic-related problems in the industry involved substantial use of single-tuned filters to offer a low-impedance path to harmonic currents. Interestingly, it is not difficult to find harmonic-producing loads in the megavolt-ampere range in the industry… Read more

A few practical ways to determine required reactive energy compensation for a power system
This article will shed some light on how adding capacitors gives the distribution system the necessary reactive power to return the power factor to the required level. Capacitors act as a source of reactive energy, which accordingly reduces the reactive… Read more

Five power quality devices that every commercial plant must have installed
Nowadays everybody speaks about power quality. For many reasons, I would say. Electrical energy is now polluted more than ever, and consumers are more sensitive to power disruptions and fluctuations than a small flower to the stronger wind. But, it… Read more

Six less known phenomena that can cause disturbance in electrical installations
In addition to the known phenomena of lightning and switching, numerous new sources, in particular power converters, can cause disturbance in installations. This disturbance, which is generated by the installation itself or carried by the system from external sources or… Read more

Five actions to achieve excellent energy savings in old electrical installations
Not all existing electrical installations lack energy efficiency, but most of them do. Especially if they were built 15-20 years ago and older. Although it is generally acknowledged that substantial energy savings are possible in most existing installations, the process… Read more

Essential fundamentals of harmonics distortion for future power quality experts
It’s quite easy to understand what is the harmonics distortion. If you take a look at the past, you must notice that power system was much cleaner and straightforward. Most loads were primarily linear in nature. Linear loads draw the… Read more
