Power quality monitoring is a fundamental requirement for ensuring the stability, efficiency and reliability of modern electrical networks, especially in critical infrastructure applications.

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.

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.

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

SATEC has added further enhancements and advanced features for power quality monitoring with the PM180. The latest release incorporates disturbance direction detection and analysis, allowing identification and location of voltage sags or voltage swells, relative to the monitoring location. The PM180 Power Quality Analyser is a Class A device for PQ metering. Damage Resulting andRead more

SATEC’s recent release of the PRO series of Energy and Power Quality Metering, brings together current technology for a compact design for an all in powerful effective line of power meters for advanced power applications, including waveform recording and AC/DC power metering.

Substations in need of automation are usually equipped with electromechanical type protective relaying for system protection. Though these existing devices may be old, they still have many years of remaining service in them.
