Single-Phase Current From a
Three-Phase Generator
Three-phase current and single-phase current
can be taken simultaneously from a generator
that is connected for three-phase service. In
the Wye Configuration, connect the load to the
three-phase leads (any two of the three leads). In
the Delta Configuration, connect the load to the
three-phase leads (any two of the three leads). In
both configurations, this connection will provide
single-phase voltage at the same voltage as
three-phase voltage.
Connect the load to any phase lead and neutral lead
of the Wye Configuration. This will produce voltage at
58% of three-phase voltage.
In the Delta Configuration that produces 240 Volts
60 Hz three-phase power, the voltages will be the
following:
•
208 Volts between the high phase and neutral
•
240 Volts between either one of the low phases
and neutral
Refer to Operation Section, “Generator Operation”
for allowable single-phase loading unbalance.
Single-phase power that is taken from a three-phase
source can be a problem. Ensure that the
single-phase loading is equally distributed.
