Description
Generator Control Module Characteristics:
The following are the electrical characteristics of the Generator Control Module:
- Voltage regulation: +/- 1% maximum over full range of generator
loading.
- Voltage transient: 13.8% no load to full load.
- Voltage transient recovery time: +/- 1% of nominal voltage within
100 milliseconds.
- Voltage modulation: 0.5% at steady state.
- Phase balance: Not to exceed 1% at balanced 3- phase load. Not to
exceed 4% at 1/3 load on 1 phase and no-load on
the other 2 phases.
- Harmonic content: Total harmonic distortion not to exceed 2%. Any
single phase harmonic not to exceed 1.5% at
0.8 P.F. linear load.
- Crest factor: 1.414 +/- 0.007
- Frequency regulation: +/- 0.1% no-load to full-load and overload.
- Frequency transient: +/- 2.5% no-load to full load
- Frequency transient recovery time: +/- 0.5% of nominal frequency
within 1.5 seconds.
- Overload rating: 125% for 5 minutes.
- Line drop compensation: Provides a voltage increase of 10 volts,
line to neutral, to compensate for
voltage drop in the aircraft cable
assembly.
