Panel-mounted | digital three-phase 380V power network analyzer | 85-265VAC | 100-330VDC | 16GB | Ethernet | RS485 | RJ45 | Modbus

The analyzer is designed not only for basic electrical parameter measurement but also for professional power quality diagnostics. The device analyzes harmonics and interharmonics up to the 63rd order, performs sampling at 1024 samples per cycle, records voltage sags, swells and interruptions, can capture transient events as short as 20µs, record waveforms and register events with 1ms time resolution.

The analyzer records forward and reverse active energy, four-quadrant reactive energy and apparent energy. This makes it suitable not only for consumption measurement but also for systems where energy can flow in both directions, such as solar power plants, energy storage systems or local generation.

The device is designed for professional power quality monitoring and supports IEC 61000-4-30 measurement methods as well as IEC 61000-4-15 flicker analysis. Integrated functions include analysis of harmonics, interharmonics, voltage deviation, frequency deviation, three-phase imbalance, voltage fluctuations, flicker, rapid voltage changes, voltage sags, swells and interruptions.

• Class 0.2S active energy metering – high accuracy for energy audits, metering and energy-flow analysis.
• ±0.1% voltage and current measurement accuracy for professional electrical system diagnostics.
• 63rd-order harmonic and interharmonic analysis helps identify distortion caused by inverters, UPS systems, variable frequency drives and other non-linear loads.
• 1024 samples per cycle provide high-speed waveform analysis.
• Transient capture down to 20µs allows extremely short network disturbances to be recorded.
• 16GB internal memory for long-term storage of statistical and event data.
• PQDIF and COMTRADE standard data formats simplify professional data analysis in external systems.
• 2x Ethernet, 2x RS485 and USB provide extensive integration capabilities.
• Modbus RTU/TCP, IEC 61850 and GOOSE allow the analyzer to be integrated into SCADA, EMS and power automation systems.
• Bidirectional energy metering is suitable for solar plants, energy storage systems and local generation facilities.
• 4 relay outputs and 6 digital inputs allow not only monitoring but also integration of warning and automation functions.

• Professional device: due to its extensive functionality, proper parameter configuration and data interpretation require knowledge of electrical engineering and power quality analysis.
• Current measurement: nominal 1A or 5A current inputs are designed for operation through appropriately selected current transformers.
• The correct measurement input version must be selected: the technical specification provides nominal measured voltage options of 57.7/100V or 220/380V.
• Not a portable meter: the device is intended for stationary panel mounting in an electrical or automation cabinet.
• Not suitable when nominal input limits are exceeded: excessive measurement voltage or current may damage the device or reduce measurement accuracy.

A data centre operates UPS systems, server power circuits, variable frequency drives and other sensitive loads. A three-phase power quality analyzer is installed in the electrical panel and continuously measures voltage, current, power and energy flows. 63rd-order harmonic analysis helps identify distortion caused by non-linear loads, while 1024 samples per cycle and transient capture down to 20µs help detect short-duration disturbances. In the event of a voltage sag, swell or interruption, the device records the event time, duration and parameters and can save the waveform. Data is transferred via Ethernet to a SCADA or energy management system for further analysis.

Active energy measurement accuracy is Class 0.2S, while reactive energy accuracy is Class 1.0.

The device analyzes voltage and current harmonics up to the 63rd order and supports interharmonic analysis up to the 63rd order.

Yes. The device supports both three-phase three-wire and three-phase four-wire measurement configurations.

The technical specification lists nominal voltages of 57.7/100V or 220/380V. The specific required input version must be selected according to the measurement system.
