Overview: Temporary Class A PQ Investigation

PQube 3 Portable is used where a permanent analyser is not required or where the monitoring point changes from site to site. It gives engineers a practical way to capture voltage sags, swells, interruptions, harmonics, transients, conducted emissions, energy consumption and load behaviour during a defined investigation period.

It can operate as a standalone logger using USB for configuration and data download. When connected to a network, it can send event notifications and daily, weekly or monthly reports directly to users, helping reduce repeated site visits and manual data extraction.

Key Benefits

Power Quality and Energy Monitoring

PQube 3 Portable provides high-quality power event recording and energy visibility. It is suitable for identifying whether supply events are causing equipment trips, control faults, production interruption, UPS transfer events or unexplained process issues.

Portable Kit Contents

The PQube 3 Portable package is intended for field engineers who need to move the analyser between locations. The kit includes the analyser package, current sensors, fused voltage leads and carrying case for practical site deployment.

Technical Highlights

Typical Applications

Standalone and Network Operation

PQube 3 Portable can be used as a standalone field analyser where network access is not available. Engineers can configure the unit and download data using a USB stick. Where Ethernet or network access is available, the analyser can send event notifications and scheduled reports automatically.

• Standalone operation using USB stick for configuration and data download.
• Network operation for remote access and automatic reporting.
• Event notifications after power quality disturbances.
• Daily, weekly and monthly reports when connected.
• Useful for temporary deployment at multiple customer or site locations.

Why Use PQube 3 Portable?

Many power quality problems are intermittent. They may not happen during a short site visit, and they may not be captured by normal power meters. PQube 3 Portable gives engineers a practical way to leave a Class A analyser at site long enough to capture the real event.

• Faster deployment compared with permanent panel installation.
• Captures real power quality events during normal operation.
• Provides waveform evidence instead of assumptions.
• Supports power quality, energy and environmental correlation.
• Can be moved between different sites or feeders.
• Useful before deciding on permanent PQ monitoring points.

Integration with IoTWatt 4.0 and Monitoring Systems

PQube 3 Portable can be used together with IoTWatt 4.0 during power quality investigations and temporary monitoring projects. PQube 3 provides high-resolution PQ event data, while IoTWatt 4.0 can provide energy dashboards, equipment trends, tickets and longer-term operational context.

• Use PQube 3 Portable for temporary high-resolution event capture.
• Use IoTWatt 4.0 for ongoing energy and equipment analytics.
• Correlate PQ events with production, energy and operational behaviour.
• Support energy audits, EECA reporting and power quality investigations.
• Convert investigation findings into permanent monitoring recommendations.

Recommended Deployment Checklist

• Confirm the voltage system, wiring configuration and monitoring objective.
• Confirm CT range, CT placement and feeder access before site work.
• Confirm temporary voltage lead connection points and safety isolation requirements.
• Confirm the monitoring duration required to capture intermittent events.
• Decide whether standalone USB operation or network reporting is required.
• Record site operating conditions during the monitoring period for event correlation.
• Review waveform records, RMS trends, harmonic levels, conducted emissions and energy profile after retrieval.
