Harmonics – a costly problem easily solved
Have you ever wondered how harmonic distortion occurs?
Are you worried whether it will affect your installation?
What is meant by harmonics?
In an ideal situation, an electrical AC power network provides a voltage with as basic frequency a sinusoidal waveform of 50 or 60 Hz. All electrical equipment is designed for optimum performance on an ideal power supply source. Harmonics are voltages and currents containing whole multiples of the basic frequency. Harmonics distort the pure sinusoidal waveform. Power electronics as used in rectifiers, frequency converters, UPS, lighting dimmers, televisions and many other devices, absorb non-sinusoidal power. This non-sinusoidal current affects power and distorts voltage to a greater or lesser extent, depending on the strength or weakness (short-circuit power) of the power supply network. In general: the more switching power electronics at a location, the greater the harmonic distortion.
Harmonics lower reliability, cause downtime, affect production quality, increase operating costs and lead to a lower productivity. Danfoss has solutions that offer you the opportunity to connect big loads to your network without the risk of unacceptable distortion levels. Under certain circumstances our solutions can “eliminate” existing harmonics, resulting in an improvement of the existing situation.
Optimise energy efficiency by reducing harmonics
Danfoss Drives’ wide range of solutions offers you support to repair weak networks, increase network capacity, attain retrofit requirements and protect sensitive environments.

Rittal - New F-gas RegulationRead moreThe new European F-gas Regulation (EU) 2024/573 has been in force since 11 March 2024 and will be phased in gradually from 1 January 2025. The regulation is an important pillar of the European climate strategy and has one clear goal: to drastically reduce emissions of fluorinated greenhouse gases and ultimately phase them out completely by 2050. This has far-reaching consequences for the choice, use and future availability of refrigerants in industrial refrigeration and air conditioning systems.

Plukon - Scanning for the futureRead moreThe Plukon poultry slaughterhouse in Blokker has installations from all kinds of machine builders and suppliers. Each of these has its own control system and associated components from different brands. This situation has developed over time, with the result that Plukon lost track of the overall picture. When it became clear that many components were now obsolete, the company decided to have itsme carry out a FactoryScan. ‘This gives us more peace of mind and helps us to better plan the replacement of components for the future.’

Damen - Modbus on boardRead moreAt Damen Shipyards Group, field service engineers fly all over the world to provide service and carry out repairs. In addition to mechanics and electronics, communication networks are becoming increasingly important, with Modbus as the standard protocol. To brush up on their people's knowledge, Damen went in search of Modbus training. The shipbuilder chose itsme because of the customisation and flexibility that the industrial service provider could offer. ‘Nowhere else could we find this level of expertise.’ Translated with DeepL.com (free version)
