Indicates how oil-immersed transformers may be operated in different conditions of ambient temperature and service, without exceeding the acceptable limit of deterioration of insulation by thermal effects. For very large transformers, e.g. 100 MVA and above, the advice of the manufacturer should be followed. For transformers with forced oil circulation, the guide is rather conservative and the loads indicated may probably be exceeded, but again the manufacturer should be consulted.
