Focus on: Voltage Stabilisers with IREM modular system – New Sterostab Y328

The voltage and current harmonics superimposed on the fundamental have combined effects on the equipment and devices connected to the electrical network. Some non-linear loads determine a harmonic content distributed over a very wide spectrum, therefore variable both in the harmonic order and in the intensity.

The harmonics in electrical systems are electrical currents or sinusoidal electrical voltages that have a frequency equal to an integer multiple of the frequency of the distribution system, called the fundamental frequency. By overlapping the Fundamental Current and the Fundamental Voltage respectively, they cause the distortion of the waveform.

Voltage imbalances are one of the most common Power Quality problems in three-phase electrical networks. Being often overlooked, they can cause serious damage to electrical and electronic equipment.

All the news of IREM Power Quality Line are illustrated in the new 2020 catalogue.

One of the most important factors in Power Quality is the continuity of the electricity supply service and therefore the lack of interruptions in the electricity supply.

With the advent of new technologies and new sources of renewable energy, the quality of the power supply has become a very important element for the proper functioning of electrical and electronic equipment that requires power supply with constant and unperturbed parameters. For these reasons, Power Quality is characterized by an increasing importance both in the industrial sector and in the service sector.
