The PQube 3 Class A Power Quality Analyzer is a high-performance, permanently installed power quality monitoring instrument designed to continuously measure, record, and analyse electrical power systems with IEC 61000-4-30 Class A accuracy. Developed for utilities, industrial facilities, commercial buildings, renewable energy systems, hospitals, data centres, and critical infrastructure, the PQube 3 captures every significant power quality event—including voltage sags, swells, harmonics, flicker, transients, interruptions, frequency variations, and waveform disturbances—with reference-grade precision.
Unlike conventional energy meters, the PQube 3 provides complete waveform recording and event analysis, allowing engineers to quickly identify the root cause of electrical disturbances. Its integrated web server, automatic email notifications, and remote monitoring capabilities ensure that power quality events are documented and reported in real time without requiring continuous manual supervision. This makes it an ideal solution for compliance reporting, troubleshooting intermittent electrical faults, validating utility supply quality, and protecting sensitive equipment.
The modular DIN-rail design allows expansion for additional measurement channels and environmental sensors, making the PQube 3 suitable for both small installations and complex power monitoring systems. With comprehensive data logging, Ethernet connectivity, and seamless integration into SCADA, Energy Management Systems (EMS), and Building Management Systems (BMS), the PQube 3 delivers actionable insights that improve electrical reliability, reduce downtime, and support predictive maintenance strategies.
Whether deployed in substations, manufacturing plants, renewable energy installations, or commercial facilities, the PQube 3 provides continuous visibility into power quality, helping organisations maintain compliance, improve operational efficiency, and minimise costly electrical disruptions.
