Meatrol MQ41 three-phase power quality analyzer — Portable Rogowski Coil with Harmonic & Data Logging
1 737.00 $
The MQ41 is a three-phase power quality analyser for live-circuit installation via Rogowski coils or voltage-output CTs — no load disconnection required. It supports single-phase and three-phase systems (3P4W and 3P3W configurations), making it well-suited for distribution board inspections, solar inverter commissioning, and industrial load audits.
Measured parameters include voltage, current, power, energy, harmonics up to the 50th order, voltage unbalance, and voltage swell/dip/interruption event logging. All data is stored on an internal 32 GB TF card in CSV format and exportable via USB.
Dual communication interfaces — RJ45 Ethernet (Modbus TCP) and RS485 (Modbus RTU) — allow integration with SCADA, energy management, and building automation systems. The unit fits a standard 96×96 mm DIN panel cutout and operates on 95–265 V AC supply.

This three-phase power quality analyser is ideal for:
- Non-intrusive measurements using Rogowski coils without disconnecting conductors
- Monitoring voltage, current, power, energy, and power factor in single- and three-phase systems
- Analysing power quality, including harmonics (up to 50th order), voltage dips/swells, and phase imbalance
- Recording load profiles, peak demand, and waveform data for diagnostics
- Supporting accurate sizing of PV systems, inverters, batteries, and generators
- Identifying inefficiencies such as poor power factor and uneven load distribution
- Logging and exporting data (32 GB, CSV) and integrating into systems via Modbus TCP/RTU (Transmission Control Protocol/Remote Terminal Unit)
The results from the MQ41 power quality analyser can be used for the following:
- Non-intrusive measurements using Rogowski coils (RC) without disconnecting conductors
- Monitoring voltage (U), current (I), power (P/Q/S), energy (kWh/kvarh), and power factor (PF) in single- and three-phase systems
- Analysing power quality including harmonics (THD – Total Harmonic Distortion, up to 50th order), voltage dips/swells, and phase imbalance
- Recording load profiles, peak demand (kW/kVA), and waveform data for diagnostics
- Supporting accurate sizing of PV systems, inverters, batteries, and generators
- Identifying inefficiencies such as low PF and uneven phase load distribution
- Logging and exporting data (32 GB, CSV) and integrating via Modbus TCP/RTU for EMS/SCADA systems
This 3-phase power quality analyzer includes (integrated components & capabilities):
- Power quality analyzer unit with 3.5″ IPS display
- Internal 32 GB memory (TF card) for data, event, and waveform recording
- Voltage input channels (A, B, C, N) for direct or transformer connection
- Current input channels (A, B, C, N) for Rogowski coils (RC) or CTs (Current Transformers)
- Ethernet (RJ45) interface for Modbus TCP communication
- RS485 interface for Modbus RTU communication
- USB port for data export (CSV) and firmware updates
- Configurable data logger, event recorder, and waveform recording
Note: External current sensors (Rogowski coils or CTs) are required but not confirmed as included in the package.
Key Features
- Live-circuit installation without load disconnection — compatible with Rogowski coils (RC) and current transformers (CT)
- Comprehensive power quality measurement — includes THD (Total Harmonic Distortion), TOHD (Total Odd Harmonic Distortion), TEHD (Total Even Harmonic Distortion), 1st–50th harmonics
- Voltage event detection per EN 61000-4-30 — records dips, swells, and interruptions
- 32 GB onboard data logging — waveform recording up to 8 kHz, CSV export
- Dual communication — Modbus TCP/IP (Transmission Control Protocol/Internet Protocol) and Modbus RTU (Remote Terminal Unit)
- Bidirectional energy metering — active, reactive, apparent energy + CO₂ (carbon dioxide) tracking
- Peak demand monitoring — active (kW), reactive (kvar), apparent (kVA) demand tracking
- K-factor calculation — transformer load impact analysis (US/EU methods)
- Phasor and unbalance analysis — voltage/current vectors and phase imbalance detection
- Multi-language interface — 3.5″ IPS display, configurable phase naming (ABC / L1-L2-L3)
