Physical meaning of "HUFL", "HULL", "MUFL", "MULL", "LUFL", "LULL" values?

The High/Mean/Low values are the exact transformer load at the record time, not the average load over 15 minutes. Actually, our device is recorded at the second level, we just pick up 15-min values. And the High value stands for the High input of the transformer, and the next level output is Mean and Low, such that you can always find that High >= Mean + low.

So the transformer basically has one primary and two secondary windings, and you measure HUFL/ HULL, i.e. active/reactive input power on the high voltage side (HV primary transformer winding). And also you measure output powers on medium and low voltage side (secondary medium voltage and secondary low voltage windings)? And the oil temperature correlates with the power losses in transformer. That makes sense, thank you!
