STATIONARY MEASUREMENT OF NETWORK QUALITY (24/7)
Stationary measurements are an essential tool to permanently (24/7) control the power quality and to detect disturbances early. For the selection of the right stationary measuring device, the state of the available expert knowledge as well as the application should be considered. For very extensive analyses and troubleshooting, it is recommended to consult a Power Quality specialist.

Conclusion
In the permanent monitoring of power quality, the applications and objectives of the measurement define the specific measuring device. In some cases, different measuring devices are also used in the distribution areas (outlets), as individual sections may require different assessment criteria. The respective performance and features are also directly reflected in the purchase price.
