- Chapter 9: Aircraft Electrical System › Generator Controls › Generator Controls for High-Output Generators
output is not within the specified tolerance, then the generator contactor is not allowed to connect the generator to the load bus. Reverse Current Sensing If the generator cannot maintain the required voltage level, it eventually begins to draw current ... instead of providing it. This situation occurs, for example, if a generator fails. When a generator fails, it becomes a load to the other operating generators or the battery. The defective generator must be removed from the bus. The reverse…
- Chapter 9: Aircraft Electrical System › Large Multiengine Aircraft › AC Power Systems
employ a split-bus power distribution system. During normal conditions, each engine-driven AC generator powers only one main AC bus. The buses are kept split from each other, and two generators can never power the same bus simultaneously. This ... very important since the generator output current is not phase regulated. (If two out-of-phase generators were connected to the same bus, damage to the system would occur.) The split-bus system does allow both engine-driven generators…
- Chapter 9: Aircraft Electrical System › Generator Controls › Functions of Generator Control Systems
When field current is controlled, generator output is controlled. Keep in mind, this system is manually adjusted and would not be suitable for aircraft. Aircraft systems must be automatic and are therefore a bit more complex. There are two basic ... types of generator controls: electromechanical and solid-state (transistorized). The electromechanical type controls are found on older aircraft and tend to require regular inspection and maintenance. Solid-state systems are more modern and typically considered to have better reliability…
