Abstract :
Generator control unit (GCU) in Boeing 737-800NG is an aircraft
component has function to control, regulate, and protect the generator when it?s
operated. But generator control unit could get trouble which damage aircraft
electrical power system. One of the problems that might happen is integrated drive
generator (IDG) which could not be controlled by generator control unit causing
generator produce over voltage.
Method that used to handle overvoltage damage on generator control unit is
do the BITE test and detailed testing use automatic test equipment (ATE). Then do
the steps troubleshoot of generator control unit.
Overvoltage could be handled with replacement of printed wiring circuit
board (PWB) in generator control unit. Then re-testing to make sure that generator
control unit is not causing overvoltage.
