On the 747 Classic, the CSD Oil Temp indicator is hard wired to CSD OIL OUT temp and there is a push to test button to monitor CSD OIL TEMP RISE. I don't know why you would want to monitor CSD Oil temp rise instead as the limit of 148 deg.C is based on Oil Out temp.
You meant to ask KW, KVA and KVAR, didn't you?
KW = The measure of real power delivered
KVA = The apparent power output of a generator which depends on the power factor %. The engine driven generators on the classic are rated at 60 KVA which is equivalent to 57 KW.
KVAR = An indication of the reactive load on the generator. Balanced readings are insurance that voltage regulators are functioning properly.
