When it comes to choosing the right power quality meter, one of the key factors to consider is the accuracy class of the meter. Two of the most common accuracy classes in the industry are Class A and Class S.

In today’s energy-driven world, ensuring optimal power quality is crucial for maintaining the efficiency and reliability of electrical systems.

Power quality, or PQ for short, relates to the reliability and consistency of the electric energy delivered by the grid. Since the grid is a closed ecosystem, overall power quality is as well influenced by the character of electric loads feeding off the power grid.

As modern electrical grids evolve with the increasing integration of renewable energy sources and the complexities of smart grid technologies, the need for precise and comprehensive power quality (PQ) monitoring has never been greater.

The world is increasingly being powered by solar and wind, and switching to use Inverter-Based Resources to leverage these renewable energy sources.

SATEC model PM180 Power Quality Meter can provide Phasor Measurement Unit (PMU) per IEEE C37.118.1 (Wide Area Monitoring System) PM180 PMU Features The SATEC PM180 is a Power Quality metering controller used to estimate the magnitude and phase angle of an electrical quantity: magnitude measurement of three-phase voltage and current synchrophasors. The estimates are calculated from the input signal waveformsRead more
