SATEC c191 Harmonic Manager Power Quality Meter

The SATEC C191HM Harmonic Manager is a compact, panel-mounted three-phase power meter and harmonic analyzer built for electrical switchboards and substations. It delivers basic voltage, current, frequency, and power measurements—plus energy, power factor, and both active and reactive energy—along with total harmonic distortion (THD), total demand distortion (TDD), and harmonic data for individual orders up to 40, including harmonic angles. The Harmonic Manager capability extends this data with per‑phase harmonic measurements and the ability to analyze harmonic power direction through PAS software, plus synthesized voltage and current waveforms accessible via PAS. On the front, a three-window display presents up to 45 pages of data with adjustable update intervals and auto-scroll on the main pages for quick diagnosis. Designed for 136×136 mm square cut-outs, the C191HM integrates into standard panel installations and supports Modbus communications via a documented protocol, enabling integration with control rooms and SCADA systems. This model sits in SATEC’s C191 family as a dedicated harmonic management add‑on to a basic powermeter, providing a focused set of power quality metrics suitable for monitoring harmonic content, energy trends, and power factor in industrial environments.
