a.) Phase Sequence: Site engineer can check the phase sequence
of input voltage supply. Meter consider
10th terminal as reference. For correctly
measurement of phase sequence following
condition must meet
1. R Phase voltage input must be connected
at 10th terminal of the meter.
2. In case of delta configuration, All of 3
phase must be connected.
Sample screen for some possibilities is
depicted below
Let it be a case of star (3P4W) configuration. As seen
from the connections, phase sequence is R, B & Y. This
same thing can be seen on display under diagnosis
para meters, As seen in sample screen, phase
sequence is R B Y. (R phase is not shown as it is
taken as reference.)
Let it be a case of delta (3P3W) configuration. As seen
from the connections, phase sequence is R, Y & B. This
same thing can be seen on display under diagnosis
para meters, As seen in sample screen, phase
sequence is R Y B. (R phase is not shown as it is
taken as reference.)
If network is configured as Single phase, then phase
sequence doesn’t matter and meter start showing
“----”.
