Three-
phase
Three-phase
: The generator and busbar are three-phase, and there are
current measurements on all three phases. Voltage and current
measurement on the neutral phase (N) is optional.
Three-phase (2 CT, L1-L3)
: The generator and busbar are three-phase.
However, the controller only uses the current measurements on L1 and L3.
Voltage and current measurement on the neutral phase (N) is optional.
Split-phase L1-L3
: The waveforms are offset by a half-cycle (180
degrees) from the neutral wire. This is sometimes called single-phase in
the USA.
Split-phase L1-L2
: The waveforms are offset by a half-cycle (180
degrees) from the neutral wire. This is sometimes called single-phase in
the USA.
Split-phase L2-L3
The waveforms are offset by a half-cycle (180 degrees)
from the neutral wire. This is sometimes called single-phase in the USA.
Single-phase L1
: The generator and busbar are single-phase. Use the L1
terminal for the voltage and current measurements (not the L2 or L3
terminals). The current measurement on the neutral phase (N) is optional.
Single-phase L2
: The generator and busbar are single-phase. Use the L2
terminal for the voltage and current measurements (not the L1 or L3
terminals). The current measurement on the neutral phase (N) is optional.
Single-phase L3
: The generator and busbar are single-phase. Use the L3
terminal for the voltage and current measurements (not the L1 or L2
terminals). The current measurement on the neutral phase (N) is optional.
Some of the controller protections are irrelevant in a single-phase
configuration (for example,
Current unbalance
,
Voltage unbalance
and
Phase sequence
).
