The new 430 Series II Three-Phase Power Quality
and Energy Analyzers offer the best in power qual-
ity analysis and introduce, for the first time ever,
the ability to monetarily quantify energy losses.
The new Fluke 434, 435 and 437 Series II
models help locate, predict, prevent, and trouble-
shoot power quality problems in three-phase
and single-phase power distribution systems.
Additionally, these models feature revolutionary
power quality and energy measurement functions
that help facilities reduce electrical power con-
sumption, and improve the performance and lifes-
pan of electro-mechanical equipment. Below you
will find brief descriptions of these new features.
Unified power measurement
Previously, only experts could calculate how much
energy was wasted due to power quality issues;
utilities could calculate the cost, but the required
measurement process was beyond the reach of
average electricians. With the new, patented
Unified Power function of the 430 Series II, you
can use one handheld tool to determine how much
power is being wasted, and calculate exactly what
the extra consumption costs.
Fluke’s patented Unified Power Measurement
System provides the most comprehensive view of
power available, measuring:
• Parameters of Classical Power (Steinmetz 1897)
and IEEE 1459-2000
• Detailed Loss Analysis
• Unbalance Analysis
These UPM calculations are used to quantify the
fiscal cost of energy loss caused by power quality
issues. The calculations are computed, along with
other facility-specific information by an Energy
Loss Calculator that ultimately determines how
much money a facility loses due to wasted energy.
PowerWave data capture
For some users, loads switching is a cause of power
quality problems. When loads switch on, the
current draw sometimes causes the voltage to drop
to a level that causes other equipment to malfunc-
tion. The PowerWave function available in the 435
and 437 Series II models enables users to capture
voltage, current and frequency signals simultane-
ously at a high speed to see which interaction is
potentially causing problems.
PowerWave goes beyond standard power qual-
ity measurements; PowerWave’s fast data capture
mode enables system dynamics to be characterized.
Waveforms for voltage and current are continuously
captured for the specified time, and are displayed
on screen in high detail; the power waveform is
derived from the data. In addition, half-cycle RMS
values for voltage, current, power and frequency
can be stored and retrieved for analysis. This
feature is particularly useful for testing of standby
generation systems and UPS systems where
reliable switch-on can be vital.
Power inverter efficiency
Power inverters take DC current and transform it
into AC current, or vice versa. Solar generation
systems usually include an inverter that takes the
DC energy from the solar cells and converts it to
useful AC power. Inverters can lose performance
over time and need to be checked. By comparing
the input power with the output power you can
determine the system efficiency. The 435 and 437
II models can measure the efficiency of such invert-
ers by simultaneously measuring the DC and AC
power of a system to determine how much power
is lost in the conversion process.
400 Hz
By increasing the power frequency to 400 Hz,
transformers and motors can be much smaller and
lighter than at 50 or 60 Hz, which is an advantage
in aircrafts, submarines, space crafts, and other
military equipment and hand-held tools. The
437 II model captures power quality measurements
for these types of avionic and military systems.
