Generator failure and possible consequences
On a recent MY A330 flight we boarded with broken APU and shortly after TO lights and other cabin electrics failed. We were advised that the the "generator had tripped". They reset generator and shortly afterwards all lights went out again. Notwithstanding more than half a dozen resets, we spent the remaining 3 plus hours until touchdown in darkness. We were told that there was a serious problem with the generator.
Apart from a number of questions this may raise, I was reliably informed by A330 driver that no more than ONE reset is recommended due to vulnerability of wiring in A330.
