We have been working on development of Resilience Series of Programmable DC Power Supplies. As part of the requirements, Power Factor (PF) of 0.9 and above needs to be achieved. The experimental setup to validate the power factor consists of a PE-DAQ system (USM-3IV & intelliSENS DAQ), which enables 3 phase power measurements as shown in the connection diagram. The analysis is performed in 3 wire 3 watt-meter configuration by pairing phase voltages and currents U1-i1, U2-i2 and U3-i3 accordingly. Applying these settings in intelliSENS power analysis tab is important for accurate power quality measurements.
