Although this table has value related to losses for older

existing transformers, it is not accurate for transformers

that the Navy has been procuring through NAVFAC guide

specifications such as NFGS-16272. The no load losses derived

from the NFGS are lower than those in this table. The load

losses for larger transformers derived from the NFGS are lower

than those in this table.
