3-PHASE ALTERNATORS
("DELTA" CONFIGURATION)
The Stationary Emergency Generator is designed
to supply 3-phase electrical loads. Electric power is
produced in the alternator power windings. These
windings were connected at the factory to the main
circuit breaker with a “Delta” configuration as shown
in Figures 7.5.
The rated voltage between circuit breaker terminals
E1-E2, E1-E3 and E2-E3 is 208V.
The rated voltage between E1 or E3 and the neutral
point 00 is 120V.
