Metrel MI-2992 Class A Power Quality Analyser – Professional Three-Phase PQA with 10.1″ Touchscreen for EN 50160 & IEC 61000-4-30 Compliance Testing
The Growing Challenge of Power Quality in Modern Electrical Systems
Australia’s electrical infrastructure is undergoing rapid transformation. The proliferation of variable speed drives, LED lighting, solar inverters, EV charging stations, and data centre equipment has fundamentally changed the nature of electrical loads across commercial and industrial facilities.
These non-linear loads generate harmonic distortion, voltage fluctuations, and transient events that compromise equipment performance, increase energy costs, and create compliance headaches.
For Australian electrical contractors and facility managers, the consequences of poor power quality are increasingly severe: premature equipment failures, unexplained downtime, nuisance tripping, overheating transformers, and costly energy wastage. Yet identifying the root cause requires instrumentation that meets international standards while remaining practical for field deployment.
Traditional power quality analysers often struggle to balance the competing demands of certified accuracy, comprehensive data capture, and usable interfaces that don’t require a PhD to operate.
Introducing the Metrel MI-2992: Where Certified Accuracy Meets Intuitive Operation
The Metrel MI-2992 Power Quality Analyser represents a fundamental rethinking of what a professional PQA should deliver. Built on an Android-based platform, this instrument combines the certified measurement accuracy that power quality standards demand with the responsive, intuitive interface that modern trade professionals expect.
The expansive 10.1-inch colour touchscreen transforms complex power quality data into immediately actionable insights, whether you’re standing in a switchroom troubleshooting voltage sags or conducting a week-long EN 50160 compliance survey.
Full compliance with IEC 61000-4-30 Edition 3.0 Class A ensures your measurements meet the highest international accuracy standards, while the step-by-step setup wizard means even operators new to power quality analysis can configure professional-grade monitoring campaigns within minutes.
The instrument supports simultaneous capture of events, inrush currents, transients, RVCs, alarms, and signalling analysis, providing the comprehensive dataset needed to diagnose even the most complex power quality issues.
Key Benefits for Australian Electrical Professionals
- Class A Certified Accuracy You Can Defend: Every measurement meets IEC 61000-4-30 Class A requirements, the gold standard for power quality instrumentation. This isn’t a compromise instrument that approximates results—it’s a fully certified analyser that produces data suitable for contractual disputes, regulatory compliance, and professional engineering reports. When a client questions your findings or a network operator challenges your measurements, Class A certification provides the defensible accuracy that protects your professional reputation.
- Comprehensive Harmonics Analysis: The MI-2992 captures harmonic components up to the 63rd order, providing visibility into the full spectrum of harmonic distortion affecting modern electrical systems. But the instrument goes further, measuring supraharmonics in the 2.1 to 14.9 kHz range with 200 Hz resolution. This capability is increasingly critical as switching power supplies, LED drivers, and solar inverters generate high-frequency emissions that traditional analysers miss entirely.
- Flexible Recording for Every Application: Recording intervals span from 200 milliseconds for capturing fast transient events to 2 hours for long-term trend analysis, with user-selectable averaging options including avg, min, max, and avgon. Predefined recorder profiles for EN 50160, IEEE 519, Codigo de Red, and other international standards eliminate guesswork, while custom profiles allow tailoring to specific client requirements.
- True Portable Operation: The built-in Li-Ion battery ensures continued operation during power outages—essential when monitoring unstable supplies—while the wide-range power supply (85-500 VAC) allows direct connection to virtually any electrical system. At 2.5 kg with dimensions of 320 × 230 × 60 mm, the MI-2992 strikes the optimal balance between screen real estate and field portability.
- Future-Ready Connectivity: USB Type-C, Gigabit Ethernet, Wi-Fi 802.11 ac/a/b/g/n, and Bluetooth 4.2/BLE provide connectivity options for any environment. NTP time synchronisation ensures accurate event correlation across multiple instruments, while VNC remote access allows full instrument control from any networked computer—monitor your recording campaign from the comfort of your office or respond to alarm conditions without travelling to site.
Applications Across Australian Industries
- Commercial and Industrial Facilities: Investigate power quality issues affecting sensitive manufacturing equipment, identify harmonic sources contributing to transformer overheating, and document baseline power quality for contractual handover of new installations. The four-channel voltage and current measurement capability handles single-phase through to four-wire three-phase systems with full support for open delta and other configurations.
- Solar and Renewable Energy: Commission grid-connected solar installations with documented power quality verification, investigate inverter-related harmonic issues, and monitor long-term performance against network connection agreements. Direct support for 1500 VDC systems via the optional S 2149 attenuator addresses the growing market for high-voltage solar installations.
- Healthcare and Critical Facilities: Verify power quality in hospital IT systems and operating theatres where power disturbances can have life-safety implications. Monitor UPS performance and confirm switchover characteristics meet design specifications. Document power quality for AS/NZS 3003 medical electrical installation compliance.
- Network and Utility Applications: Conduct EN 50160 compliance surveys for network operators, investigate customer complaints about supply quality, and document power quality at connection points. GPS time synchronisation via optional accessory ensures measurements can be precisely correlated with network events.
- Variable Frequency Drive Systems: The VFD mode supporting 5 Hz to 120 Hz system frequencies addresses the specialised requirements of motor drive applications, enabling power quality analysis on the output of variable frequency drives where traditional analysers cannot operate.
