Greetings
While I was reading GEK-107092d, I came across something not very clear. It talks about isolating one cooler (in case it has a failure) of the generator. Fortunately, we haven't had any cooler failures in the past. the quote is:
"If a cooler leak is severe, the defective cooler may be left out of service until repairs can be made. Generators are typically designed to operate at rated power factor at 80% rated load capacity with one hydrogen cooler out of service."
I know that we have to keep monitoring the generator RTDs in case of isolating one cooler.
My question is, what is this rated load? Is it the one on the generator nameplate?
Our generator name plate says the MVA is 228.6 and power factor is 0.85.
By doing small calculations, the rated load will be 155 MW. So 80% would be 124 MWW. Is that correct ?
