The Power Analyzer allows for the analysis of currents from dc to several MHz. Voltage
values up to 1000 V and currents up to 20 A (depending on measurement modules
installed in the instrument) are measured accurately, and the respective real, reactive, and
apparent power is calculated. The limit of error is between 0.03 % and 0.3 %, depending
on the model. See the technical specifications for detailed information. For dc and ac up
to a few MHz, it is not affected by the wave shape, frequency, or phase position. The
measuring range can be extended by connecting shunts or clamps. When extending the
range using third-party shunts or clamp, the extra errors due to these devices should be
considered. The device allows for simultaneous measuring in up to six channels.
The Fluke NORMA 4000/5000 Power Analyzer offers the following options for
connection:
• 1-phase measurement
• Aron circuit (W2)
• 3-phase measurement (W3)
Note
When connecting a 4-channel device for electrical efficiency analysis, the
3-phase power cables for this measurement should be connected to the
measuring channels 1 to 3, so that the efficiency can be calculated and
displayed directly on the Power Analyzer.
• Ensure that there is no overload at the current input of the Power Analyzer.
• If necessary, install appropriate fuses.
XW Warning
To avoid possible electric shock or personal injury:
• Risk of injury when touching connections, internal circuits
and measuring devices that are not connected to earth
ground.
• Always adhere to the instructions regarding the sequence
of connection (see Chapter 5, “Connecting Sequence”).
The difference between the connection of the voltage input between the current input and
the mains (Figure 5-1) or between the current input and the load (Figure 5-2) is that, in
the first case, the leakage power of the current input, and in the second, the leakage
power of the voltage input is added to the measuring result. As the leakage power of the
current input may increase up to ~2 W at 10 amp versus a leakage power of the voltage
input of 0.5 W at 1000 V, it is preferable to use the second method. It is used for the
further diagrams, also in Aron and 3-phase measurements. For special applications such
as active current sensors without power loss or higher leakage power at the voltage input
with the “star point adapter,” method 1 is preferable.
The connecting leads to the shunts should be as short as possible in order to prevent
interference and noise voltages.
XW Warning
To avoid possible electric shock or personal injury:
• Do not touch sensing terminals. The sense terminals at the
shunts are powered with the same voltage as the power
connections.
• Shunts are not isolated. Never touch the sense terminals at
the shunts.
• Risk of injury when touching connections, internal circuits,
and measuring devices that are not earthed.
• Always adhere to the instructions regarding the connection
sequence (see Chapter 5, “Connecting Sequence”).
Where the current to be measured exceeds the rating of the direct current connection, an
external triaxial shunt should be used, see Figure 5-3. Fluke triaxial shunts are
recommended as they provide high accuracy across the full frequency range. Standard
linear shunts may produce excessive errors due to the possible presence of high
frequency that components experience with electronic loads. The NORMA internal shunt
is optimized for such loads.
In Figures 5-3, 5-6, and 5-9, Fluke recommends using MCS measuring
leads for triaxial shunts and MCP leads for planar shunts. Triaxial shunts
are equipped with guard connectors in the plugs and planar shunts are
equipped with guard sockets.
Measurement with Voltage and Current Transducer
Figure 5-4 shows the connections for measurements with a voltage and current
transducer.
W Caution
To prevent damage to the transducer due to overload, check
transducer rating.
Note
Transducer errors limit the measuring bandwidth and reduce the intrinsic
uncertainty.
XW Warning
To avoid possible electric shock or personal injury:
• Risk of injury when touching connections, internal circuits,
and measuring devices that are not connected to earth
ground.
• Always adhere to the instructions regarding the sequence of
connection (see Chapter 5, “Connecting Sequence”).

The Aron circuit is only available for 3-wire networks, see Figure 5-5. It is only required
to measure two phases (currents I1 and I2 in the following connection diagrams), as
I1+I2+I3 must be 0.
Note
In most cases, the Aron circuit is not acceptable for measurements on
inverters, as there are capacitive leakage currents from the windings to the
housing.
• Ensure that there is no overload at the current input of the Power
Analyzer.
• If necessary, install appropriate fuses.
To select the Aron, or 2-wattmeter, Method, go to General Setup and select W2. Select
channels 2 and 3 for the connections. For more information, see Chapter 7,
“Configuration.”
Scaling transformers for voltage and current may be used in this mode but care needs to
made in identifying the correct channel and measurement index information.
Note
The W2 mode is not provided for the second set of three phase inputs with
the 4 or 6 channel versions of the NORMA 5000.
XW Warning
To avoid possible electric shock or personal injury:
• Risk of injury when touching connections, internal circuits,
and measuring devices that are not connected to earth
ground.
• Always adhere to the instructions regarding the sequence of
connection (see Chapter 5, “Connecting Sequence”).
Figure 5-8 illustrates a direct connection for a 3-phase measurement. Ensure that there is
no overload at the current input of the Power Analyzer. If there is a potential risk of
overload at the current input, incorporate a shunt or transducer into the circuit. If
necessary, install appropriate fuses.
To select the 3-phase (W2) method, go to General Setup and select W3. For more
information, see Chapter 7, “Configuration.”
XW Warning
To avoid possible electric shock or personal injury:
• Risk of injury when touching connections, internal circuits
and measuring devices that are not connected to earth
ground.
• Always adhere to the instructions regarding the sequence of
Figure 5-9 illustrates the connections for a 3-phase measurement using a shunt. The
connecting leads to the shunts should be as short as possible in order to prevent noise
voltages.
XW Warning
To avoid possible electric shock or personal injury:
• Do not touch sense terminals. The sense terminals at the
shunts are powered with the same voltage as the power
connections.
• Shunts are not isolated. Never touch the sense terminals at
the shunts.
• Do not touch connections, internal circuits, and measuring
devices that are not connected to earth ground.
• Always adhere to the instructions regarding the sequence of
connection (see Chapter 5, “Connecting Sequence”).
Figure 5-10 illustrates the connections for a 3-phase measurement with a voltage and
current transducer. In 4-wire power systems, the common (N) of the 3 voltage
transducers is connected to the neutral line. In 3-wire power systems, the common (N) of
the 3 voltage transducers is left open to create a star point. Alternately, you can connect
to the star point of a wye-connected load or to earth if the internal star point of the power
system in connected to earth.
W Caution
To prevent damage to the transducer due to overload, check
the transducer rating.
Note
Transducer errors limit the measuring bandwidth and reduce the intrinsic
uncertainty.
3-Phase Measurement (W3) 5
XW Warning
To avoid possible electric shock or personal injury:
• Risk of injury when touching connections, internal circuits
and measuring devices that are not connected to earth
ground.
• Always adhere to the instructions regarding the sequence of
connection (see Chapter 5, “Connecting Sequence”).
In systems with three voltage wires, the three wires should be connected to the HI
terminal and the LO terminals should be connected together.
However, in high frequency switching electronics systems such as drives, inverters, and
UPS, this method has additional errors due to high frequency components being shunted
to the ground connection. To compensate for this error, use the star point adapter, see
Figure 5-11.

Press measuring key WAV three times. The rms values for power in channels 1 through 3
are displayed.
The numbers in subscript for U or I (in the example, U1 or U2) indicate the respective
channel.
Note
As the Power Analyzer requires a complete voltage and current cycle for an
accurate measurement; a full period is automatically added to the average
time of 300 ms of configuration 1:W3, and the new average time is
displayed (for example: 309.9 ms at 22.585 Hz, corresponding to seven
periods).
Prior to measuring, you must configure the default settings, adjust channels, measuring
ranges and times, and synchronize current and voltage sources.
If you wish to reapply certain settings at a later stage, you must save the configuration.
You have the option to save up to 15 user-defined configurations, which are
automatically assigned the names 10:USER to 24:USER.
Configuration
When first switching on the Power Analyzer, factory configuration 1 and 2:W2 is used.
This configuration is suitable for measurements with fundamentals below 100 Hz
(average time 300 ms, synchronization source U1, low-pass filter 100 Hz).
Mode W3 is the standard configuration for three phase, 3-wattmeter measurement and
single phase measurement. Channels 1, 2, and 3 are used for three-phase measurements in
a 3-channel instrument, considering three-channel average values and totals. In 4-channel
instruments, channel 4 acts as an independent single channel. In 6-channel
configurations, the W3 connection operates as two independent three-phase systems.
In 4- or 6-channel instruments where the W2 configuration is selected, the channels
higher than 3 operate as the W3 configuration.
Note
You have the option to modify the settings for configuration 1:W3. If you
wish to save the new settings, you must do this in a new configuration.
Default configuration 1 and 2:W2 cannot be overwritten. You may save new
settings in the process or at the end of the configuration procedure. Settings
that have not been saved are lost when the device is switched off or when a
different configuration is loaded.
You may:
• Modify configuration 1:W3 loaded upon startup of the device
• Load an existing configuration
• Create a new configuration
• Delete or modify an existing configuration

For signal analysis like DSO (scope) or harmonic analysis (FFT) with digital sampling
procedures, you need to consider Shannon’s sampling theorem that states: “The sample
frequency must be, at minimum, double that of the highest signal frequency.” If not
considered, it may result in display values (frequencies or waveforms) that do not exist,
in other words, aliasing.
If you want to measure numeric time-based mean values like rms, rectified mean, and
mean, you do need not observe Shannon’s theorem. For the precision of the results, only
the number of samples is important, not the sampling frequency (average time >> cycle
duration). The sampling signal must be statistically independent, which means the
sampling frequency must not be close to, or a multiple of, the signal frequency.
Note
To operate in the “undersampling mode,” the anti-aliasing filter must be
turned OFF at the current and voltage channel (see the earlier section
“Configure Current and Voltage Channels” in this chapter).
The Fluke NORMA 4000/5000 Power Analyzer is designed for the measuring of currents
and voltages for up to three different channels. The Power Analyzer calculates rms
values, real, apparent and reactive power, and other derived values. The accuracy is not
affected by the wave form, frequency, or phase shift. Harmonics may be displayed to a
maximum of half the sampling frequency.
Default settings are available for loading quick setups. In addition, you can define more
specific settings to save and load as required (see, "Configuration" in Chapter 7). The
Power Analyzer begins a measurement as soon as the configuration is set and the device
is switched on.
Prior to Measuring
Connect Power Analyzer to the mains (power) socket.
1. Check the measuring connections at the Power Analyzer.
2. Switch on the Power Analyzer.
Measuring with Default Configuration
If the default configuration is acceptable, no additional steps are required.
Ensure that the factory configuration is loaded (see, "Load Configuration" in Chapter 7).
Measuring with User-Defined Configuration
If custom analysis is required, load the respective configuration (see "Configuration" in
Chapter 7).
Note
If measurements with an external shunt or probe are required, make sure
that there is no signal connected at the direct current inputs. Signals on
both inputs (external- and direct-current input) can damage the
measurement unit.
The description that follows is for a W3 configuration. The W2
configuration is basically the same with some differences. In W2, some
values are invalid and are suppressed. The phase voltage does not exist and
is replaced by the phase-to-phase voltage, reactive power, and apparent
power and are available as totals only.
After switching on the Power Analyzer, the display shows the numerical values measured
in channel 1.

You can configure and display up to nine variables (values). To change the
user defined display size, see the next section.
You can change the size of the numeric display in the user defined screen. You can select
between three sizes:
Size Description
3 three numeric values, double size
6 six numeric values, common size (7 mm)
9 nine numeric values, with size 5 mm
Press function key 3/6/9.
User defined values are shown in desired size.
The changing of the display size is done in a loop, every time you press the
function key 3/6/9.
You can change the size in the configuration menu and also in the
measurement menu.
Save User Defined Screen
Save the configuration settings by pressing the SAVE function key.
See details about saving a configuration in section "Save Configuration" in Chapter 7.
Back to Common Numeric Screen
• Press function keys Back... or Esc
• The recently used numeric screen is shown.
Change View Mode
After having selected a channel and the relevant measured values, you have the option to
change to different view modes where the parameters are shown in the form of numerical
values, vector graphs or oscilloscope graphs.
For details regarding the numerical display of measured values, refer to the section,
“Measure Voltage, Current and Power,” in Chapter 8.
Up to six signals of the H01 fundamentals can be viewed as vector graphs.
The vector graphs show voltage and current with amplitude and phase shift, and allow for
the fast assessment of signals and detection of errors in the connections.
1. Press measuring keys Σ or 1...n and WAV to call up the desired values, that is,
values measured at WAV power.
2. Press measuring key Vector graphs.
The measured values are shown in the form of vector graphs.

3. To view a different channel or different measured values in vector graph form,
press measuring keys Σ or 1...n and WAV.
Adjust Scale
The scale of the vector in the vector diagram is adjustable.
1. To automatically optimize the scale of the graph, press function key Default.
4. To view a different measure parameter, press function key Detail again.
5. To return to an overview of all measured values for channel 1 in oscilloscope
format, press function key Detail again.
6. To view a different channel or different measured values in oscilloscope graph
form, press measuring keys Σ or 1...n and WAV.
The oscilloscope display can be optimized in a number of ways.
1. To automatically scale the graph, press function key Default.
The scale is set to steps of 5 ms.
2. To change the scale of the axes, press function key Scale.
Adjust the scale, using the cursor keys:
Cursor Key Function
Enter Confirm settings
Esc Exit scale mode
3. Adjust the scale of the axes using the cursor keys, and press Enter and Esc.
The oscilloscope display with the adjusted axes is shown.
Adjust Zero
1. Press function key Offset.
2. Adjust the zero point by using the cursor keys and press Enter to confirm.
The oscilloscope display with the adjusted zero point is shown.
Recorder View
The recorder allows you to monitor measured values, by recording the mean measured
values over time. This function is particularly useful for the detection of trends and
amplitude variations. The actual graph depends on the configured range and average time
(see the section, “General Setup,” in chapter 7). Prominent variations in the graph
indicate errors in the measuring system.
To view the recorder:
1. Press measuring keys Σ or 1...n and WAV to call up the values, for example,
current measured at channels 1 to 3.
2. Press measuring key Recorder.
The display shows a recording of the measured values.
The option to choose between a linear or logarithmic Y-axis is available by using the F1
function key, the cursor keys can be used to adjust the frequency axis zoom factor and
position.
1. Press function key F1. The mode of the Y-axis changes to the mode shown in
esn103.eps
the respective softkey field (→ lin or → log).
The scale of the graph changes from linear to logarithmic or vice versa (here:
change to logarithmic).
esn104.eps
2.To change the scale of the X-axis, press function key zoom.
You have the option to view individual measured values or a group of up to three values
(that is, all measured values of a channel) in graphic or table format. By default, the
measured values are shown in graphic format.
1. Press function key → table.
The data is now shown in a table in numerical format (shown here, current on
channel 1).
Harmonic Order Mode
View Harmonics
1. Press function key mode to switch directly to mode DFT and call up a table showing
the integer harmonics.
Switching between FFT and DFT is even possible in HOLD mode and
therefore allows different views on the data from the same single interval.
2. Alternatively, use function key Config to select mode DFT in the harmonics setup
screen. Afterwards, press Esc to return to the measurement screen.
Modes FFT and DFT share the same frequency range setting.
1. Use function key Config to open harmonics setup screen. Press Enter and select STD
mode with the cursor keys. Press Enter to confirm.
2. Select number of cycles (N) per analysis interval (200ms @ nominal frequency).
Only settings of 10 (for 50 Hz) and 12 (for 60 Hz) are defined by the EN standard,
the other values (4, 6, 8) are provided for convenience to have a faster update rate
when analyzing lower frequency signals.
Analysis interval length = N / f

3. Select grouping mode according to EN standard:
none No grouping, basic spectral components (absolute RMS only, no THD)
harm Harmonic components Y
hgrp Harmonic groups Y
hsgrp Harmonic subgroups Y
isgrp Inter-harmonic subgroups Y
sgrp Harmonic & inter-harmonic subgroups Y
THDT
