Verify meter readings
Check the voltage and current readings on the PQube 3 Portable 480V
using the touchscreen.
From the display, press the [Meters] button and check that the measured values
are correct. If you entered PT and CT ratios into your setup file, verify the
voltage and current readings are primary units. Also verify the values for power
(watts) and power factor are correct. If you have inverted your CTs or installed
the CTs on the wrong phases, your power readings will be inaccurate.
Verify the voltage and current vectors are correct. The vector convention for a
balanced 3-phase system is L1 voltage is 0°, L2 voltage is -120° and L3 voltage is
+120°.
If the touchscreen display is not accessible, verify the meter readings by
connecting your laptop to the local network, or directly into the PQube 3 Ethernet
port.
