Specified Transformer Losses
**************************************************************************
NOTE: On LANTNAVFACENGCOM projects, use "Specified
Transformer Losses". Delete "Specified Transformer
Efficiency", "Transformer Loss Calculations", and
"Deduct Clause". The appropriate NLL and LL values
at the 100 percent review. Until that time, leave
the following bracketed values blank.
**************************************************************************
No-load losses (NLL shall be [____] watts at 20 degrees C, and load losses
(LL) shall be [_____] watts at 85 degrees C. The values for the specified
losses shall be used for comparison with the losses determined during the
routine tests. If the routine test values exceed the specified no-load
losses by more than 10 percent, or the total losses exceed the specified
total losses (sum of no-load and load losses) by more than 6 percent, the
transformer is unacceptable.
