| L-1011 Trainer - AC/DC Power Control Relays |
The AC/DC Power System buildout is finally finished!! A short moment to celebrate :) Getting the power systems right certainly took a lot more than I personally had anticipated. In order to make the power distribution look and feel as close as possible to the real thing we, in essence, built a miniature version of the actual power distribution system with all the AC and DC busses present in the L-1011. This made this a lot more complicated, but also a lot more rewarding. All in all, a good 60 hours went into building the power system.
The two images below show the finished DC and AC systems prior to us dressing up the cables and making it all look a lot cleaner.

All this crazy cabling stuff in the two images above is controlled by the neat and easy to read "Electric System" panel on the lower F/E station (image below). However, all the magic behind the panel is implemented with 72 control and sense relays.

The image above shows the L-1011 as would be typical at the gate powered by External Power. The three engine generators are off and the FIELD and GENERATOR breakers show "OPEN". The External Power is switched onto the AC Tie Bus and the Tie Bus Breakers (white flow bars) are closed to power the AC Bus 1, 2 and 3.
