B787 Hybrid <strong>Electric</strong>al Power Distribution System Conventional (B767) B787 Centralized distribution: circuit breakers, relays and contactors Unclassified Remote distribution: solid‐state power controllers and contactors 32
B787 Hybrid <strong>Electric</strong>al Power Distribution System (Cont.) The level of power of the B787 ram air turbine (RAT) has increased dramatically Compared with B767 single 90 to 120 kVA per engine Center hydraulic system is powered by two large 30 GPM / 5000 PSI electric‐motor driven hydraulic pumps (230 VAC), compared with B767 two 7 GPM / 3000 PSI electric‐ motor driven pumps + 37 GPM / 3000 PSI single air driven pump (ADP) Unclassified Expanded electrical system generating twice as much electricity than conventional aircraft 33
