    Learn and understand the technical terms in power quality. Have a talk with the course instructor about your power quality challenges, contact Bo Rohde Pedersen.

    01. Intro power quality

    Power quality is an important factor for many, but often is this underestimated. In factories can power quality problems introduce production errors that can be difficult to quantify. In private homes can it lead to malfunctions in appliance. The term “power quality” covers many aspects from under-voltage, dropouts, harmonic distortion, and high frequency noise. There are multiple sources of error and parameter that sets the power quality.

    Locating and solving power quality can be a big puzzle. First has the problem to be characterised, measured over time and multiple places as time synchronized data. The data has to be analysed and with good knowledge can the problem be solved.

    Throughout the course, studens will review examples of general technologies that are disturbed by poor power quality and the factors that address specific systems. Problems can both rise in the electricity grid, where for example, wind turbines can pose challenges or at a manufacturer where errors occur as a result of incomprehensive production.

    02. Theory: Harmonic currents in practical use

    It can be a big challenge to find the cause and then solve a problem. This course provides participants with an understanding of power quality terminology and the use of analytics tools for troubleshooting. Students will obtain an understanding of frequency analysis, harmonic distortion, high frequency noise and flicker through a working process. Examples of components that can induce power quality problems are illustrated both theoretically and through practical exercises.

    03. Practice use of power quality logs

    Practical exercises and use of instruments are in focus. It is possible to bring your own equipment and get guidance in using it through the practical exercises. We look at how LED bulb, DC power supplies and frequency converter load the electricity grid in individual exercises, in addition to some cases Rohde Consulting has solved. Every day several practical exercises are performed.

    In the course, studens use standardised class A measuring instruments, which can be
    connected to the main supply from 230V-400kV.

    04. Qualifications after the power quality course

    After the course, the participant can set up and operate a power quality instrument, including interpret of data. In addition, the ability to troubleshoot a power grid. Knowledge of relevant standards and in-depth with EN 50 160.
