Applications:
The use of a K-rated transformer is anywhere non-linear loads are present. Prime uses would be in factory automation, computer rooms, and office buildings because of the high harmonic content in these areas, Typically a K-13 rated transformer is sufficient for most applications. UL recognizes K-factor values of 4, 9, 13, 20, 30, 40 and 50. The K-factor number tells us how much a transformer must be de-rated to handle a definite non-linear load or, conversely, how much it must be oversized to handle the same load.
How to choose your K factor transformer?
K1: standard transformers, standard lighting, motors.
K4: Induction heater, SCR, AC drive
K13: School pulse lighting, hospital
K20: Data processing computer, computer room.
