Maintain and manage power supplies and analyze problems more easily and reliably than ever before

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. Transient voltages Voltage swells Voltage dips Interruptions Frequency fluctuations Inrush current Harmonics High-order harmonics Unbalance

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.

International standard IEC 61000-4-30 Ed. 2 Class A compliant

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; 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.

High-voltage, wideband performance

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.

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. Applications • Simultaneous measurement/monitoring of the primary (AC) and secondary (DC) sides of an EV rapid charger • Simultaneous measurement/monitoring of the primary (DC) and secondary (AC) sides of a solar power system • Simultaneous measurement of the primary (DC) and secondary (AC) sides of a DC/AC (3-phase) inverter • Simultaneous measurement of the primary and secondary sides of a UPS • Simultaneous measurement of power supply (AC) and control (DC) circuits • Simultaneous measurement of a 3-phase line and a ground line • Simultaneous measurement of a neutral line to detect ground

Verify the quality of power supplied by an 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, 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.

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. *For more precise inverter measurement, HIOKI recommends the POWER ANALYZER PW6001 or PW3390.

No need for an external power supply

Since sensor power is supplied by the instrument, there's no need for an AC adapter when using AC/DC sensors or flexible sensors.

400 Hz line measurement

In addition to 50/60 Hz, the PQ3198 can measure a line frequency of 400 Hz.

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.

Easy-to-understand display of parameters

Since you can switch the display to show all measurement parameters while measurement is underway, it's easy to check conditions. *Screenshot shows the PQ3100 display.

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.

Simple setup functionality for simplified configuration of recording parameters

Simply choose the preset that suits your application, and the instrument will automatically configure the recording parameters.

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.

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. < Quick Report function > Group together trend graphs for multiple data sets and output them as a report. This feature is useful when you wish to compare dates from a repeat recording run or data from multiple locations. < Display a list of analytical data > Display detailed measurement data, including event statistics, an event list, and event graphs. Simply choose the parameters you need to output to the report.
