1. POWER ANALYZER FEATURES, QUICK OVERVIEW, SAFETY
The Infratek 108B High Precision Power Analyzer is available in 1-, 3- and 4- phase versions.
All voltage inputs (ranges 0.3V up to 1500Vpeak) and all current inputs (1.5mA up to 1A;
15mA up to 5A; 1A up to 40A; and current shunt inputs 60mV up to 6V) are potential free and
exhibit
 Excellent low noise
 Common mode suppression
 DC-stability
 Wide frequency range (2MHz)
 Very low self-heating on current inputs.
There is no need to fiddle with dc-compensation, or changing current plug-ins. All is built into
the input sections of the Power Analyzer, ready to be used.
Your intuition will guide you to operate the Power Analyzer touch screen correctly. With basic
knowledge of power measurement, you will be able to change the settings to your needs. Al-
most all setting changes are accomplished with two touches on the display screen or two
clicks with the mouse.
Figure 1.1 Shows the display of a 4-phase instrument in “Standard Mode”.
Figure 1.1 shows the display of a 4-phase instrument in “Standard Mode”. To change the cur-
rent range from 15mA to 500mA touch the button “AUTO A”. A pop-up window is presented
from which you select “500mA”. Now the Power Analyzer is in 500mA current range (manual
ranging).

Figure 1.2 108B Value Selection Table
Just as simple is to change the quantity at the bottom line “Freq” to Arectified mean (Arect).
Touch “Freq” at the left side of the display. This will present you a value selection table as
shown in Figure 1.2. Now touch “Arect” which brings you back to Figure 1.1 with the bottom
line quantity changed to “Arect”.
Four different measure modes enhance the 108B Power Analyzer capabilities. These are:
standard measure mode, logging measure mode, transient measure mode, and power-speed
measure mode.

ODE
In the Standard Measure Mode 280 quantities per phase are continuously measured
(no gaps) and are updated. Values can be displayed on four display pages, can be saved in
internal memory, or on a memory stick, or can be transferred via Interface to a computer.
Touching “WAVE” will display a sub-menu which lets you select the current-, voltage-, and
power wave forms of any phase.
Select “OFF” (Wave OFF). Now you have access to the buttons “FFT Table”. Touching
“FFT Table” selects “FFT L1”. On five pages you can now view the harmonics of current, volt-
age, power, and phase angle (harmonics 1 to 40 for current and voltage, harmonic 1-21 for
power and phase angle).
Similarly, selecting “FFT Bar” the bar graph of the harmonics will be displayed in percent of
the fundamental (1. harmonic).
Touching “FFT L1” will toggle to “FFT L2”, “FFT L3”, and so on.

The basic operation is as follows: Select the number of cycles for which you desire a periodic
data output to the RS232- / USB-interface. If you perform measurements on the 50Hz power
line and you select cycles = 1 you obtain new data every 20ms; if you select cycles = 30000
you obtain new data every 10 minutes.
Before starting the measurement, a valid synchronization signal 5Hz to 2kHz must be applied
to all installed phases of your Power Analyzer. Select Sync A, Sync V, or S_Ext V. Touch the
START-button to start the measurement, touch the STOP-button to stop it. DC signals can
also be measured (e.g. DC-motors). For DC you must apply an external synchronization sig-
nal in the frequency range 5Hz – 2kHz (select EXT synchronization).
Furthermore, the frequency of the synchronization can be varied up and down as much as
10% per second.
From every phase you obtain 8 values: frequency, RMS current, RMS voltage, power, power
factor, apparent power, energy Wh, and apparent energy VAh.
If you select the baud rate of 463.2 kBaud (in SETUP) a 4-phase Power Analyzer transmits
8 x 4 = 32 values in less than 20ms. This can be used to analyze the start-up behaviour of
power systems.

The transient measure mode can be used in two ways: You can catch current-, voltage-, and
power wave forms in a start-up on all phases simultaneously or you can view all wave forms
at a critical operating point in Standard Measure Mode (up to maximum 4 phases).
The duration of the measurement is set by changing in the SETUP menu the Transient-id
from 0 to 7. Sections of the wave forms can be expanded by simply touching one of the 4
“Zoom Sectors” (maximum zoom factor is 256).
For proper operation you must apply signal synchronization to all installed phases of your
Power Analyzer.

This measure mode analyzes the performance of electric devices such as electric cars.
In 20ms intervals the following data are stored in internal memory: RMS current, RMS volt-
age, power, apparent power, energy, apparent energy, and speed of an axis or a wheel. Rms
current and –voltage are average values of the number of phases used, power and energy
are the sums of phases used.
Power speed measurements can be performed on DC- as well as AC-drives using either
phase 1, or phase 1 and phase 2, or using phase 1, 2, and phase 3 of the Power Analyzer.
At the end of a measurement cycle (maximum 11 seconds) data versus time are plotted, can
be expanded to view details, or can be stored.

1.5 POWER ANALYZER REAR PANEL
Figure 1.5 shows the 108B rear panel with four phases installed. Every phase consists of a
potential free voltage input along the top side.
Below the voltage inputs are the 40A input, and the 5A input (7A max.) with common Lo
socket. Above the 40A socket is the 3 pole Amphenol socket for the 1A input and shunt input.
It is normally covered with the shunt short circuit cap.

All four current inputs are referenced to the black Lo socket and are potential free.
Figure 1.6 3 pole Amphenol Socket for 1A current input and shunt input
For use of 1A input remove the shunt short circuit cap and insert the 1A adapter. The 1A
adapter is the Hi input, and the black current socket is the 1A Lo.
Caution: When 1A adapter is removed the shunt short circuit cap must be inserted.

2. CONNECTION TO CIRCUITS
Please read section “Safety” of this manual before performing the measurements described
below.
2.1 MEASUREMENT IN 3-PHASE MAINS CIRCUIT
2.1.1 THREE WATTMETER CONNECTION
Power and energy consumed by a load are positive values. This means that current Hi and
Lo, and voltage Hi and Lo must be connected in correct directions (polarity).
Rule 1: All currents flow from supply to load that is into the red current socket and from
current Lo (black socket) to input of load.
Rule 2: Connect current Lo to voltage Hi.
Connect all voltage Lo to power line neutral (3 wattmeter circuit)
Figure 2.1 Power Measurement in 3-phase mains circuit with neutral line using three
Wattmeter configuration. Rule 1 and Rule 2 apply.
Power values of the 3 phases are all positive. You can verify that power of phase 1 becomes
negative by reversing current phase 1.

page 13
2.1.2 ARON CONNECTION
Important! Do not use Aron Connection for unsymmetrical loads.
Figure 2.2 Measurement in 3-phase mains circuit using 2 Wattmeter configuration.
Rule 1 and Rule 3 apply.
Rule 3: Voltage Lo connects to third wire not used for current measurement
(Figure 2.2). Phase to phase voltages are measured.
The 2 Wattmeter circuit measures 2 currents, and 2 line-to-line voltages and determines total
power of the 3 phase load. One of the displayed power values can become negative due to
phase shifts of inductive loads. This may lead to confusion. Therefore, strictly follow rule 1
and rule 3.
