Course Description
Harmonic currents are often the cause of the overloading of capacitors, motors, transformers, and cables. Due to harmonics, processes can be interrupted, which is typically the case in situations with a weak supply, such as electrical installations on board of a ship. This course introduces the characteristics of harmonics and possible harmonic problems. In addition, the course clarifies matters such as the ideal sine wave, possible disturbances of this sine wave, the characteristics of harmonics, the interaction between the distortion in the current and voltage, costs associated with harmonics and this course exemplifies in several case studies the interaction between the distortion in the current and the voltage.
