3-PHASE ALTERNATORS ("DELTA" CONFIGURATION)
‹
The Stationary Emergency Generator is designed to supply
3-phase electrical loads. Electric power is produced in the alterna-
tor power windings. These windings were connected at the factory
to the main circuit breaker with a “Delta” configuration as shown
in Figures 7.7 and 7.8.
The rated voltage between circuit breaker terminals E1-E2, E1-E3
and E2-E3 is 240V.
The rated voltage between E1 or E3 and the neutral point 00 is
120V.
