Power quality

Optimizing quality of current and voltage

This course gives you insight into the sources decreasing the quality of current and voltage, the consequential problems and possible solutions. The performance of installations depends on the quality of current and voltage (power quality). The expanding pressure on the Dutch electricity network creates a challenge in securing power quality.

High distortion of the current will result in reduced lifetime of several components, overloading or reduction of current capacity. Distortion of the voltage could also result in undesired disconnection or malfunctioning of components (and therefore processes). Several research projects indicate the high additional costs related to poor power quality.

New technologies such as electrical transportation, new types of lighting and solar panels have their own characteristics regarding sensitivity to current distortion and their own current characteristics (inrush currents, harmonic currents). In this course, various problems are explained with examples of these new technologies. 

Applying power quality solutions successfully

This course handles:

  • sources decreasing the quality of current and voltage
  • possible solutions for poor power quality
  • analysis of current distortion characteristics in new technologies such as electric transport, new concept of lighting and photovoltaic systems
  • current characteristics (inrush currents, harmonic currents) of new technologies
  • examples of problems in new technologies

Intended for  

Technicians (academic or higher education) with basic knowledge of electrical engineering, working at grid operators, installation -, inspection -, measuring – and industrial companies, responsible for the design or operation of electricity networks or installations.
