Hioki PW3198 Manual

Just connect to the measurement line, and the PW3198 will simultane-
ously measure all parameters, such as power and harmonic. You can
then switch pages to view the needed information immediately.
To detect power supply failures, measurement does not
need to be performed multiple times under different condi-
tions. The PW3198 can always monitor and reliably detect
all power supply failures for which detection is enabled.
PW3198 Never Misses the Moment a Power Supply Failure Occurs
Acquire the Information You Need Quickly by Switching Pages (RMS Value) Reliably Detect Power Supply Failures (Event)
A transient overvoltage is generated by a lightning strike or a con-
tact fault or closed contact of a circuit breaker and relay, and often
causes a steep voltage change and a high voltage peak.
Display parameters such as voltage, current, power, power factor,
and integral power in a single window.
The PW3198 can measure all waveforms of power, harmonic, and error events simultaneously. When a problem occurs with
the equipment or system on your site, the PW3198 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.
Transient Overvoltage (Impulse)DMM Display
Display the voltage and current
waveforms on channels 1 to 4
one above the other in a single
window.
Waveform Display
Display the measured value
and vector of the voltage and
current of each order harmonic.
Vector Display
Display the RMS value and phase
angle of harmonics from the 0th
order to the 50th either in a graph
or as numerical values.
Harmonic Bar Graph Display
Measure All Parameters at the Same Time
Display the voltage and current
waveforms on channels 1 to 4
individually.
4-channel Waveform Display
Voltage drops for a short time as a re-
sult of large inrush current generated
in the load by, for example, a starting
motor.
Voltage Dip (Voltage Drop)
An excessive increase or decrease
of the load causes the operation of
a generator to become unstable,
resulting in frequency uctuations.
Frequency Fluctuations
Harmonic is generated by a
semiconductor control device
installed in the power supply of
equipment, causing distortion of
voltage and current waveforms.
Harmonic
Voltage and current waveforms are distorted by
noise components generated by a semiconduc-
tor control device or the like installed in the power
supply of electronic equipment.
High-order Harmonic
A large current flows instanta-
neously at the moment electrical
equipment, a motor, or similar de-
vices are powered on.
Inrush Current
The power supply stops instantaneously or for a short
or long time because electrical power transmission is
stopped as a result of a lightning strike, or because
the circuit breaker is tripped by a power supply short
circuit.
Interruption
A voltage swell is generated by a lightning strike
or a heavily loaded power line being opened or
closed, causing the voltage to rise instantaneous-
ly.
Voltage Swell (Voltage Rise)
An increase or decrease in the load connected to each
phase of the three-phase power supply or an unbalanced
operation of equipment and devices causes the load of
a particular phase to become heavy so that voltage and
current waveforms are distorted, voltage drops, or nega-
tive phase sequence voltage is generated.
