Power Quality & Reliability Course

Power quality determines reliability of electrical equipment operation, performance of the assigned functions by it, service life. Problems of power quality attracted increased attention because of power quality degradation and not meeting customer expectations. Poor power quality has been shown to lead to reduced efficiencies, increased risk of downtime and higher energy and operating costs.

When it comes to power quality issues, the easiest and most effective solution to avoid unplanned shutdowns is the correction of voltage anomalies coming from the grid. This can be accomplished using harmonic filters, capacitors and other protective equipment.

Rises in non-linear and other challenging loads in modern electrical networks present unique power quality challenges. Sensitive operations, irregular loads and isolated or weaker grids demand stricter grid codes and power quality standards to safeguard the reliability of an electrical system for smooth industrial and commercial processes. Harmonics distortions, voltage variations, poor power factor and load unbalance are among the key elements that not only test the reliability of modern electrical systems but also induce overall greater system losses.

Main course features are: • Basic terminology and definitions • Voltage sags and interruptions • Effects of fault clearing on voltage • Reliability indices • Transient overvoltages and arresters • Understanding and mitigating harmonics • Analysis of AC power and steady-state voltage regulation
