Hioki portable power meters and analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The new and improved 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. New features include the ability to drive current sensors straight from the PQA and enhanced recording capabilities.

The PQ3198 is a three-phase power quality analyzer that allows simultaneous power logging and waveform capture of power quality anomalies (events).
Record up to 9999 power quality anomalies (events) and trend data up to 1 year.

Evaluate whether data complies with the EN 50160 standard by analyzing it and generating a judgment based on voltage fluctuations during the trend interval. You can also customize the judgment criteria and parameters. The IEEE 519 TDD and GB Power Quality Statistics Report are also available.

The high-order harmonic (supraharmonic) component consists of noise components of several kHz or more caused by voltage and current waveform distortions when equipment power supplies use semiconductor devices. It includes various frequency components.
The PQ3198 can measure high-order harmonics (supraharmonics) components from 2 kHz to 80 kHz.

Transient voltage occurs due to phenomena such as lightning, breaker damage, or the closure of the circuit breaker or relay.It often occurs when there is a radical change in voltage or when the peak voltage is high.

The GPS OPTION PW9005 can be used to correct the instrument's internal time to UTC standard time.This capability eliminates any time difference between instruments to allow analysis that preserves the simultaneity of phenomena measured with multiple instruments.

Get measurement results from the job site in real-time, and display/save them on your PC.
Immediately and automatically transfer power supply quality event measurement files to your PC.
The power quality analyzer itself can be remotely controlled from your PC to change event conditions.

Use GENNECT cloud, a cloud service operated by Hioki specifically for its GENNECT line of services, to realize genuinely remote measurement.Acquire measured values in real time, collect data, and control instruments via the cloud, anytime, from anywhere.

AC/DC auto-zero current sensors measure DC current accurately over extended periods of time,eliminating the need to concern yourself with zero-point drift.Since sensor power is supplied by the instrument, there's no need for an AC adapter when using AC/DC sensors or flexible sensors.

SD Card Precaution
Use only the SD Card sold by HIOKI. Compatibility and performance are not guaranteed for SD cards made by other manufacturers. You may be unable to read from or save data to such cards.

The number of power supply problems is increasing as power systems are becoming more and more complicated - all due to the rising use of power electronics devices plus a growing installed base of large systems and distributed power supplies. The quickest way to approach these problems is to understand the situation quickly and accurately. The Power Quality Analyzer is ready to effectively solve your power supply problems.

The unit can measure all waveforms of power, harmonic, and error events simultaneously. When a problem occurs with the equipment or system on your site, the analyzer will help you detect the cause of the problem early and solve it quickly. You can depend on the PW3198 to monitor all aspects of your 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.

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 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.

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 is no need to set up a separate power supply.

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.

The PQ3198 complies with the IEC 61000-4-30 Ed. 2 Class A standard. As a result, it can perform standard-mandated measurement tasks such as gapless, continuous calculation; detection of events such as swells, dips, and interruptions.

Part of the IEC 61000-4-30 international standard, Class A defines power quality parameters, accuracy, and standard compliance to facilitate the comparison and discussion of measurement results from different instruments.

The PQ3198 can measure transient voltages of up to 6000 V 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.

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, you 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.

The GPS OPTION PW9005 (not included) can be used to correct the instrument's internal time to UTC standard time. This capability eliminates any time difference between instruments to allow analysis that preserves the simultaneity of phenomena measured with multiple instruments.

Display statistics about events by date or time. This feature makes it easy to discover anomalies that occur at particular times of day or on particular days of the week. In addition, you can perform ITIC (CBEMA) curve analyses (using tolerance curves), which are used by power quality management standards in the U.S.
