POWER QUALITY ANALYZER PQ3198 and PQ3100
The critical importance of electrical power in today's society necessitates daily maintenance andmanagement 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.

PQ31003Analyze 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 datawith 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.

Applications

Investigate power supply anomalies
Investigate the causes of equipment failures
and malfunctions, including issues that are
difficult to identify, such as when a device
causes a properly-functioning piece ofequipment that is connected to the same
power outlet to experience a voltage drop.

Verify the quality of power from asolar power system

Check fluctuations in the output voltage of apower conditioner in a solar power systemalong with flicker and transient voltages. You
can also measure fluctuations in thefrequency of the grid interconnection andfluctuations in the harmonic voltage andcurrent components of the system’s output.

Verify the quality of power suppliedby an EV rapid charger

Since the PQ3198’s fourth voltage channel isisolated from its first three voltage channels,
the instrument can measure power andefficiency 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 andefficiency between input and output.

5High-precision, wideband, broad-dynamic-range measurement

The PQ3198 delivers the high-end specifications and high reliability needed to capture the full range of power anomalies andanalyze the underlying data with a high degree of precision.

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

Cla ssA

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).

Thanks to basic measurement accuracy that is among the best of
any instrument in the industry, the PQ3198 offers high-precision
measurement without the need to switch voltage ranges.

Class APart of the IEC 61000-4-30 international
standard, Class A defines power quality
parameters, accuracy, and standard
compliance to facilitate the comparisonand discussion of measurement resultsfrom 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 canalso measure high-order harmonic components from 2 kHz to 80 kHz. As inverters enter into widespreaduse, malfunctions and failures in that frequency band are becoming more common.

Simple inverter 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.

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.

Prevent power supply problems

Measure voltage fluctuations, equipment
capacity, and harmonics before installing
new electrical equipment. You can also
check whether newly installed equipment isaffecting other equipment by repeating thosemeasurements
after
installation
andcomparing the results.

Discover signs of impending problems byrepeatedly measuring a component such as
an elevator motor on a regular basis. Flexible
current sensors make it possible to connect
the instrument safely and easily, even indifficult settings involving double wiring,busbars, and crowded distribution boards.

Perform load rejection testing ofsolar power systems

In load rejection testing, it’s necessary torecord transient changes in current andvoltage when the system is taken offline. The
PQ3100 can record anomalous waveforms
for up to 11 seconds (1 second before and
10 after each event). Cursor measurement
lets you verify peak values and duration as
well.

Simultaneously record event waveforms and trend graphs

Each time it makes a measurement, the PQ3198/PQ3100 records trend data for all parameters. When a power anomaly
is detected, an event is recorded. Since the instrument records the maximum, minimum, and average values during theinterval, you can rest assured that you won’t miss peak values.

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 thedisplay while measurement is in progress.

30 sec. event fluctuation trend data

When a voltage swell, dip, or inrush current event occurs, thePQ3198/PQ3100 can simultaneously record 1/2 RMS value

Features shared by the PQ3198 and PQ3100

Designed to accommodate every possible application
so that it’s easy to use in all field settings
Clamp sensors for every application
Flexible sensors: Easy installation in confined
locations

Flexible current sensors provide a convenient way to measuredouble- and triple-wired power supplies and in confined
locations, with capacities of up to 6000 A.

No need for an external power supply

Since sensor power is supplied by the instrument, there’s noneed for an AC adapter when using AC/DC sensors or flexible
sensors.

Auto-zero sensors: Stable measurement of DC powerover extended periods of timeAuto-zero current sensors allow measurement of DC power overextended periods of time, eliminating the need to concern
yourself with zero-point drift.

Wide array of ranges to accommodate all applications

Use HIOKI sensors in an array of applications to measureequipment ranging from the secondary side of CTs to high-current
wiring. The CT7136 offers three ranges* (5 A/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.
*PQ3100 (PQ3198: 2 ranges [50 A/500 A]).

Delivering both safety and high accuracy
Exceptional safety

The PQ3100 supports CAT III (1000 V*) and CAT IV (600 V)
situations, so it can safely measure service drops and distribution
panels with a terminal-to-ground voltage of up to 1000 V.
*PQ3100 only (PQ3198: CAT IV [600 V]).

High accuracy

The PQ3198 complies with IEC 61000-4-30 Ed. 2 Class A, and
the PQ3100 with IEC 61000-4-30 Class S, ensuring both
instruments’ ability to deliver highly reliable, high-precision
measurement.

Not supported

A messages is displayed if the user pressed the F key on the FILE

Automatic detection ofcurrent sensors

When selected on the settings screen, connected sensors that support the HIOKI PL 14 connector are automatically detected.

Processing in the event If the instrument is equipped with a BATTERY PACK Z1003 with a remaining charge, the instrument will switch automatically to battery power andof a power outage
continue recording. If no charged BATTERY PACK Z1003 is installed, measurement will stop (settings will be preserved), and the instrument will
start recording again when power is restored. However, integrated values and other data will be reset.
