3.3 Functions
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
are measured accurately, and the respective real, idle and
apparent power is calculated. The limit of error is between 0.1%
and 0.3%, depending on the model. 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 caters for simultaneous measuring in up to
6 channels.

5.4 Aron circuit (triaxial/guard technique)
5.4.1 Direct connection
the Aron circuit is only available for 3-wire networks.
It is only required to measure two phases (currents I1 and I2 in the
connection diagram), as I1+I2+I3 must be 0.
Important
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.

This chapter contains an introduction to the measuring procedures
that can be carried out with the power analyzer, based on a simple
sample measurement. The example used here is a measurement
at the frequency converter with a fundamental below 100 Hz.
Connection to
circuits
Configuration
Connect the outputs of the frequency converter to the current
and voltage channels of the power analyzer (see chapter 5.5.1
“Direct connection”, page 19).
Switch on the power analyzer.
Measuring
Ensure that factory configuration 1:W3 is loaded (see chapter
7.2: "Load configuration", page 23).
The settings of factory configuration 1:W3 are as follows:
- Low-pass filter on, set to 100 Hz
- Average time set to approx. 300 ms, depending on the
measured frequency
- Synchronisation source is U1.
Press measuring key WAV three times.
The rms values for power in channels 1 ... 3 are displayed.
The numbers in subscript (e.g. U

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. Example: 309.9 ms at 22.585 Hz,
corresponding to 7 periods.

The synchronisation source determines the frequency on which
the analysis is based. In factory configuration 1:W3, the
synchronisation source is U1, as this signal tends to be reliable in
most cases.
The following options are available:
- Input at device (channel 1 ... 6), current or voltage
respectively (U1 ... U6, I1 ... I6)
- Ext for external synchronisation signal (connection to port
for external synchronisation signal)
- OFF, if no synchronisation source is used (e.g. measuring
+
of direct current)
Note
To measure the start-up of a machine, you might opt for an external
synchronisation signal (0,2Hz to sample rate, max. 50V), as there is
otherwise no signal at the beginning of the measuring procedure,
and thus no measured values.

7.11 Undersampling / Aliasing
If you want to make signal analyses like DSO (scope) or harmonic
analyses (FFT) with a digital sampling procedures you need to
take care about Shannon’s sampling theorem which says: “The
sample frequency must be minimum double than the highest signal
frequency”. If you do not keep this rule you will get results
(frequencies or waveforms) that do not exist in truth (=Aliasing).
Power Analyzer NORMA 4000, NORMA 5000 37
EO1111G REV G
Page 40
Configuration
If you want to measure a numeric time based mean values like
rms, rectified mean, mean…you do not need to take care about
Shannon’s theorem. For the precision of the results only the
number of samples is important, not the sampling frequency
(average time >> cycle duration). But you have to consider that the
sampling signal must be statistical independent, that means the
sampling frequency must not be close or a multiple of the signal
frequency.
Note
To work in the “undersampling mode” the anti-aliasing filter has to
be turned OFF at the current and voltage channel (see chapter 7.6
“Configure current and voltage channels“ page: 30).

Measuring process
8 Measuring process
The power analyzer is designed for the measuring of currents and
voltages through up to three different channels. It calculates rms
values, real, apparent and idle power and other derived values.
The accuracy is thereby not affected by the wave form, frequency
or phase shift. Harmonics are output to maximum half the
sampling frequency.
You have the option to apply the default settings or a user-defined
configuration. If you wish to use a user-defined configuration, you
must first define and save the respective settings and then load the
relevant configuration (see chapter 7: "Configuration", page 22).
The power analyzer begins to measure as soon as the measuring
arrangement is set up and the device is switched on.
8.1 Prior to measuring
Connect power analyzer to the mains socket.
Check the measuring connections at the power analyzer.
Switch on the power analyzer.
Measuring with
default
configuration
Measuring with
user-defined
configuration
If you want to complete an analysis using the default configuration,
no additional steps are required.
Ensure that the factory configuration is loaded (see chapter
7.2: "Load configuration", page 23).
If you want to complete an analysis using a user-defined
configuration, load the respective configuration see chapter 7
"Configuration", page 22).
Important
If you want to measure with external shunt or probe please 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.
