The harmonic study shows the influence of harmonic voltages and currents. For some harmonic orders, the impedance seen by the network may be so high that its presence causes equipment heating and consequently reduced equipment life. Power electronics components such as rectifiers can send harmonic currents to the provider network exceeding what is acceptable. The analysis of harmonic sources in the industry requires deep understanding of latest power electronics components. The rectifier bridges for example gives rise to current sources most of which are known and accessible. Other less common types of installation have sufficiently varied harmonic spectra so that more adequate models are required to properly mitigate – in a targeted manner – the harmonic orders that causes the worst effects. Our experts will validate the impact of harmonic sources in your network and this in perfect compliance with the standards.
