Power Quality is the quality of your voltage and current. Characteristics such as frequency, size, waveform and harmonic distortion are subject to changes in the network and loads in the company. If the network quality is not optimal, malfunctions and damage to the installation and equipment can occur. In addition, maintenance costs and energy consumption are higher. By optimizing the network quality, we ensure continuity of your processes. Continuous power quality monitoring helps to detect, follow up and prevent problems.

We find out where the grid disturbances come from, measure voltage dips, voltage interruptions, voltage fluctuations, determine the available power and the reserves ... we do this via short grid analyzes as well as permanent measurement setups.

In addition to low-frequency problems, we can also analyze EMC failures and propose solutions. For more complex problems, we can always count on the input of the professors of our partner Ghent University.

We publish regularly. You can click here for a list of our scientiffic publications.


In the event of voltage dips, appliances can be switches off unwanted. This in itself leads to a production stop and flickering of the lighting.

Frequency variation

Frequency variations occur by incidents on the net. For example, by not switching off production units in time. As a result, equipment using the zero crossing for synchronization has deviations.


The emission and immunity levels of equipment differ from those of the operating environment. This can cause malfunctions on control equipment, delays in data communication and damage to electrical equipment.


Non linear loads cause overload in transformers and cables. Devices connected to the grid can malfunction. This causes malfunction and a shortened service life. Fire damage also occurs and the energy loss is higher.


This problem occurs by switching on inductive or capacitive loads or by lightning strikes. As a result, components will malfunction or be damaged. Devices can also malfunction and the security equipment is switched off.


When switching large motors, pumps, compressors and lift motors, medical equipment may malfunction and lighting may flicker.

Voltage and current unbalance

Voltage unbalance often occurs with single-phase loads. Motors are heated up, safety devices are switched off and more energy is lost.
