Hioki PQ3198 Power Quality Analyzer

The critical importance of electrical power in today’s society necessitates daily maintenance and management to ensure that problems don’t occur. When they do, for example due to an equipment failure or abrupt surge in demand, engineers face the need to analyze the cause quickly.

The POWER QUALITY ANALYZER PQ3198 and PQ3100 provide robust support for field personnel who need to analyze power characteristics in the form of measurement capabilities that reliably captures the full range of power anomalies and exceptional ease of use throughout the entire user experience, from connecting the instrument to recording data.

Analyze Equipment Power Problems

Capture the full range of power supply anomalies, including momentary interruptions, voltage drops, and frequency fluctuations, while recording trends to help investigate the causes of unexpected equipment malfunctions and sudden stoppages.
 

Record Quality Data for Power Systems

Record fluctuations in voltage, current, power, harmonics, and flicker when connecting a highly variable system such as a renewable energy source or EV charging station to the grid.
Easily analyze the data with the included PQ ONE software.

Measure AC/DC power

Use AC/DC auto-zero current sensors to measure DC current accurately over extended periods of time.
Since the sensors are powered by the instrument, there’s no need to set up a separate power supply.
 

Capture Power Anomalies Reliably with Simple Settings

The PQ3198 and PQ3100 can measure all parameters at once, including power, harmonics, and anomaly waveforms.

Simultaneously Record Event Waveforms and Trend Graphs

Event waveform
When an event occurs, the instrument records the instantaneous waveform for 0.2 seconds.
Triggers can be set for all event parameters in parallel, and you can check recorded data on the display while measurement is in progress.

Simultaneously Record Event Waveforms and Trend Graphs

30 sec. Event Fluctuation Trend Data
When a voltage swell, dip, or inrush current event occurs, the PQ3198/PQ3100 can simultaneously record 1/2 RMS value fluctuations for 30 seconds.

Two-circuit Measurement

Since the PQ3198’s fourth voltage channel is isolated from its first three voltage channels, the instrument can measure power and efficiency across two separate circuits.
