Expert knowledge that moves you forward
We offer you power quality audits with troubleshooting in accordance with EN 50160 and IEC 61000 and support you with our expert know-how. As the market leader in the field of mobile power quality devices, we can draw on a wide range of network analyzers with the appropriate accessories for our services.
Keep an eye on supply quality and network faults
Fully automatic at every voltage level
The built-in fault recorders and network power quality analyzers PQI-DA smart, PQI-DE and PQI-D are the central components in systems handling all measurement tasks in low, medium and high-voltage networks. The analyzers can function as fault recorders with a scanning rate of up to 41 kHz, as power quality measurement devices to EN 50160 / IEC 61000-2-2/-4 or as power quality analyzers.
Above all, their components are suitable for monitoring special reference quality levels or characteristics agreed between an energy supplier and a customer, registering them and then presenting the results for analysis or storage. Modern power quality devices work to the IEC 61000-4-30 standard, 3rd edition. This standard defines measurement processes to create a comparable basis for users.
