Three-Phase Alternators (“Delta” Configuration)
The Stationary Emergency Generator is designed to sup-
ply three-phase electrical loads. Electric power is pro-
duced in the alternator power windings. These windings
were factory-connected to the main circuit breaker with a
“Delta” configuration as shown in
Figure 10-7 and Fig-
ure 10-8.
Rated voltage between circuit breaker terminals E1–E2,
E1–E3 and E2–E3 is 240V.
Rated voltage between E2 and the neutral point 00 is
208V. The rated voltage E1–00 and E3–00 is approxi
-
mately 120V.
NOTE: Voltage measured from E2 to 00 can greatly vary
when single-phase load is placed on alternator.
