MOBILE MEASUREMENT OF POWER QUALITY
Mobile measurements are usually used for measurement campaigns over time as well as for fault location. To select the right mobile meter, the level of available expertise as well as the application should be taken into consideration. For very extensive analyses and troubleshooting, it is recommended to consult a Power Quality specialist.

Conclusion
Depending on the application and the available depth of expertise on the subject of power quality, different analysis devices can be used for observation and fault detection. The higher or lower the performance of a measuring instrument is set, the more or less this will be directly reflected in the purchase price. Mobile measurements can also serve as an additional source for fault detection in permanently installed systems.
