3-PHASE DELTA STATOR W INDING:
Som e units m ay be equipped w ith a 3-phase delta
type stator w inding, show n in Figure 6. Phase rotation
is L1-L2-L3. The ^Neutral* line is designated as "LO’.
Generator Model No. 9422 uses this type of stator to
deliver 120 volts AC (line-to-neutral); or 240 volts AC
(line-to-line).
3-PHASE. W YE-CONNECTED SYSTEM:
Figure 7 show s a 3-phase W ye-Type stator w hich
has 12 AC output leads that are reconnectable to
supply several voltages. Generator Model 9318 uses
this type of statorto supply 220/380 volts AC at 50 Hertz
(i.e., 220 volts AC line-to-neutral; 380 volts AC line-to-
line).
