Three-Phase Alternators (“Delta” Configuration)
The Stationary Emergency Generator is designed to
supply three-phase electrical loads. Electric power is
produced in the alternator power windings. These
windings were factory-connected to the main circuit
breaker with a “Delta” configuration as shown in Figure
8-7 and Figure 8-8.
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
approximately 120V.
NOTE: Voltage measured from E2 to 00 can greatly vary
when single-phase load is placed on alternator.
