Derating Factor value depends upon the motor environment,

For example:

Motor design temp – 45 deg C

But motor location ambient temp 65 deg C (near any burner
or heat source)

So motor performance (rated power) will reduced due to
ambient temp.

For that motor manufacturer given Derating Factor value.

Ex:

Rated power = 45 kW

Derated power = 42 kW (Operating Temp – 50 deg C)

what is interface level and how it is calibrate?
