Active & passive harmonic filters

Efficient fault minimization

Active and passive mains filters minimize interference levels that have negative repercussions on other equipment in the power grid. This means that they compensate for harmonics, dampen resonances and thus ensure a consistently high voltage quality. These measures reduce the premature wear of operating equipment and protect sensitive control electronics from failures or defects.

Compliance with standards
and limit values

In many countries, there are strict standards and limit values regarding grid perturbations. Energy-consuming companies must ensure that their company-owned grids comply with these regulations. In the event of non-compliance, there is a risk of disconnection by the energy supplier. Conversely, the energy supplier must also ensure that it provides its customers with a grid with high voltage quality.

High voltage quality is generally defined as the correspondence between the characteristics of the mains voltage specified in the DIN EN 50160 standard with regard to the shape, level and frequency of the voltage and the actual mains voltage.

Disturbance variables and possible solutions

In the overview you will find the typical causes of the most common disturbance variables in the power grid. The possible solutions range from active and passive mains filters to high-frequency filters.
Our active filters can be freely parameterized and adjusted to meet individual requirements. Passive filters, on the other hand, are specially tuned to a specific frequency range.
