PA3000 Four-channel, Multi-phase AC/DC Power Analyzer
Efficiency Testing Three Phase Applications
DEMONSTRATION GUIDE
METHOD 2: EFFICIENCY MEASUREMENTS ON THREE PHASE PWM MOTOR DRIVE
(PWRVIEW SOFTWARE)
This method discusses efficiency measurement on three phase input and output PWM motor
drives using the PWRVIEW software.
WHAT YOU WILL NEED — METHOD 2
•
PA3000 Power Analyzer
•
PC with PWRVIEW software installed
•
Three Phase Inverter (Motor Drive)
•
USB cable
•
4mm Safety Leads
•
AC Source (Optional)
Figure 2-4. PWM Motor drive efficiency (3-phase in and 3-phase out).
TEST SETUP
1. Connect the three phase AC input of the PWM motor drive to the first two channels of the
PA3000 as shown in wiring diagram. (See Figure 2-4.)
2. Connect the three phase output of the PWM drive to the other two channels using the
configuration as shown in the wiring diagram.
NOTE: The 3-phase 3-wire (2 Wattmeter) configuration enables testing three-phase
signals by using two power channels. This method can be used for simultaneously
testing 3-phase input and outputs on a 4-channel power analyzer.
3. After making all of the power connections, connect the PA3000 to the computer with the
PWRVIEW software installed using the supplied USB cable. Ethernet or GPIB can used.
4. Open the PWRVIEW software by double-clicking the desktop icon. Click the Add button
to connect the PA3000. All available instruments will be listed in the selection panel.
Select the desired instrument (the PA3000) and then click Connect.
NOTE: There are various default applications and compliance tests on the left panel
that you can select from
