IREM has developed a High Protection Integrated Power Supply meeting the technical requirements that describe the technical specifications of the “Absorbeur d’Ondes” (AO).

High frequency disturbances are caused by the sparks generated in the AC commutator motors, the “corona effect” on the high voltage lines, the igniters of luminous signs and burners, and by the magnetic fields irradiated by radio and TV stations.

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.
