Description
Hioki portable power meters and analysers 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 analyser 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.
Power quality monitoring, troubleshooting, and energy management
Logging and waveform recording
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.
Easy to Set up
Preset
Simply choose the preset that suits your application, and the instrument will automatically configure the recording parameters.
Wiring and connection guide
The instrument will perform an automatic wiring check and display the results.
Capture power anomalies reliably with simple settings
The PQ3198 can measure all parameters at once, including power,
harmonics, and anomaly waveforms.
Transient voltages
Voltage swells
Voltage dips
Interruptions
Frequency fluctuations
Inrush current
Harmonics
High-order harmonics (Supraharmonics)
Unbalance
Standard compliant
IEC 61000-4-30 Ed. 3 Class A compliant
The PQ3198 complies with the IEC 61000-4-30 Ed. 3 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;
and time synchronization using GPS (optional).
Class A
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.
EN50160 judgment function (PQ ONE)
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.
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.
Simple inverter measurement
The PQ3198 can measure the secondary side of inverters with a fundamental frequency of 40 to 70 Hz and a carrier frequency of up to 20 kHz.It can also measure the efficiency of DC/3-phase inverters.
Verify the quality of power supplied by an EV rapid charger
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.

Other features
High-order harmonic (supraharmonic) measurement
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.
High-speed transient measurement
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 PQ3198 can measure transient voltages of up to 6000 V lasting as little as 0.5 μs (2 MS/s).
400 Hz line measurement
Power measurement for aviation systems and shipboard systems. In addition to 50/60 Hz, the PQ3198 can measure a line frequency of 400 Hz.
GPS time synchronization
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.
Intuitive software for data analysis and report creation
Analyze data and generate reports with HIOKI’s PQ ONE power quality analysis software
Group data from different measurement locations, times, and dates into folders and view them together.
Display detailed measurement data, including event statistics, an event list, and event graphs. Simply choose the parameters you need to output to the report.
Output CSV and PQDIF format files for the parameters you choose. PQDIF format files can also be uploaded to the software.
-
Statistics display function
Show voltage, current, frequency, harmonics, flicker, and other metrics on the Statistics screen. View the maximum, minimum, and average value for measurement data context.
-
ITIC curve
Automatically generate ITIC curve from recorded event. The curve estimates IT equipment’s resistance to power quality issues such voltage fluctuations.
Remote measurement
Remote Monitoring of a Site’s Power Supply Quality [GENNECT One SF4000]
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.
Escape from your LAN! Realize genuinely remote measurement
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.
Wide range of sensors for better quality measurement
Wide array of ranges to accommodate all applications
Use HIOKI sensors in an array of applications to measure equipment ranging from the secondary side of CTs to high-current wiring.
The CT7136 offers three ranges (50 A/500 A), as do HIOKI’s flexible sensors (50 A/500 A/5000 A).
Since the effective measurement range extends to 120% of the nominal range,
flexible sensors can be used to measure currents of up to 6000 A.
No need for an external power supply
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.
Automatic sensor detection to avoid erroneous measurement
Simply connect current sensors, touch “Sensor” on the screen, and the instrument will automatically detect sensor types and maximum current ranges.
