2 Check the connection/wiring
2.1
Check nearby equipment (if possible) to ensure that the voltage, current and
power is equal to the measured values in the meter.
☐
2.2
Check vector diagram. The voltage phase sequence should be
U1 red (0°) U2 green (-120°) U3 blue (+120°)
☐
2.3
Check vector diagram. Each current should be within +/-90° from its
corresponding voltage
☐
2.4 Check that PF is >0.7 on all phases as well as total
☐
2.5 Check that P is positive for each phase (if not measuring on a generator)
☐
2.6 Check that unbalance is low (high value means wrong phase sequence)
☐
2.7
Select transfer data a few times. Cancel the transfer and verify that there isn’t a
continuous trigging of sag/swells or transients due to bad settings.
☐
2.8 Erase all old data in the meter
☐
