The Hioki PQ3198/600 KIT 3-Phase 4-Wire Power Quality Analyzer Kit with Class A Compliance is designed to measure single to three-phase lines with a high degree of precision and accuracy. The PQ3198 is a power quality analyzer for monitoring and recording power supply anomalies, allowing their causes to be quickly investigated, and also for assessing power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. Features include the ability to drive current sensors straight from the PQA and enhanced recording capabilities.

The PQ3198 offers an extensive range of event parameters. This model is ideal for use in troubleshooting-related measurement since it can capture a variety of power supply anomalies. Additionally, it can measure power and efficiency across two circuits carrying different voltages (3-phase and DC, etc.).

Maintain and manage power supplies

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 PQ3198 provides 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 (600A AC sensors included) 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 with simple settings

The PQ3198 can measure all parameters at once, including power, harmonics, and anomaly waveforms. The instrument also provides simple setup functionality for automatically configuring recording parameters for popular applications.

Easily manage power quality with PQ ONE bundled application

The PQ3198 can measure transient voltages of up to 6000V (requires optional sensors) lasting as little as 0.5 μs (2 MS/s). It can also measure high-order harmonic components from 2 kHz to 80 kHz. As inverters enter into widespread use, malfunctions and failures in that frequency band are becoming more common.

Verify quality of power supplied by EV rapid charger

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. For example, users can verify the quality of the input (AC) and output (DC) of an EV rapid charger while simultaneously measuring power and efficiency between input and output.

Verify quality of power from solar power system

Check fluctuations in the output voltage of a power conditioner in a solar power system along with flicker and transient voltages. Users can also measure fluctuations in the frequency of the grid interconnection and fluctuations in the harmonic voltage and current components of the system's output.

Easily manage power quality with PQ ONE bundled application

The free PQ ONE application software for the PQ3138 Power Quality Analyzer lets users analyze captured data in fine detail and create regular power quality management reports with ease and flexibility. Investigate the cause of power anomalies in the comfort of your office using a PC.
