| The decision table for the IEEE condensed Rogers Ration Method diagnosis above includes the following codes: PD=partial discharge, TL=low thermal condition, TM=medium thermal condition (<700°C), TH=high thermal condition (>700°C), and ARC=arcing. An entry example may help: IF acetylene/ethylene ration IS high AND methane/hydrogen ratio IS medium AND ethylene/ethane ratio IS high THEN diagnosis IS transformer arcing. |
