Power Quality Analysis

Home/Solutions/Customer Applications/Power Quality Analysis

Improve overall grid reliability, avoid expensive equipment failures & resolve energy supply disputes

As any other product, electric power is characterized by quality. Power quality analysis is rewarding for electric utilities since it enables continuous monitoring, early excursion detection, root cause analysis, and timely corrective actions improving overall grid reliability. Power quality is also of interest for major energy consumers to minimize amount of power quality events and avoid expensive equipment failures. Therefore, mutual interest of energy suppliers & energy consumers in power quality motivates use of high performance power quality analysers and recorders for dispute resolutions.

SATEC devices provide high performance power quality monitoring with built-in EN50160 or IEEE1159 monitoring, statistics and reports. eXpertpower™ Pro, SATEC’s online solution for full system Power Quality Analysis, provides direct access and a robust tool set for logging and analysing Power Quality events.



Our state of the art power quality analyser PM175 provides power quality analysis according to EN50160 and IEEE1159 correspondingly, including built-in statistics and reports. These devices provide all power quality parameters required by international standards including harmonics & inter-harmonics (IEC 61000-4-7), dips/over-voltages (sags/swells), interruptions, flicker (IEC 61000-4-15), etc.
