First of all hi to everybody, i'm new here. Thank you in advance and sorry for my english.
So this happened few months ago.
While purging the generator we had and explosion and the rotor has to be replaced because of the damage, bad news. They will have to work in the stator a little bit as well.
The mechanical team purged first the hydrogen with CO2, (checking the purity) and once the purity of H2 was low enough, they started to pressurize with air.
The thing is that once they started to pressurize with air, we had no pressure of CO2 in the generator. Was it correct, or they screwed up?
Thank you very much. By the way, machine is 7FA.
