ENERGY EFFICIENT DISTRIBUTION TRANSFORMERS 
ARE CLASSIFIED INTO 3 TYPES

 Linear Load General Purpose Transformers: They are generally used for supplying 

appliance, lighting, heating, motorized machine and power loads from electrical 

distribution systems.
 Non-Linear Load K-Factor Transformers: Energy efficient K-factor transformers are 

designed to tolerate heating due to harmonics associated with non-linear loads.   
 Harmonic Mitigating Transformers: Harmonic Mitigating transformers are superior 

to K-rated and general purpose Transformers in that they reduce voltage distortion (flat-

topping) and power losses due to current harmonics created by single-phase, non-linear 

loads such as computer equipment.


K-Factor
 It is an index of the transformer’s ability to carry harmonic currents while operating 

within the temperature limits of its insulating system. 
 K-Factor values range from 1 to 50. 
 Standard transformers have a K-factor of 1.0 and are assigned for linear loads only.  

K= [(I1/Irms)2 (1)2]+[(I2/Irms)2 (2)2]+[(I3/Irms)2 (3)2] +…………….+ [(In/Irms)2 (n)2]

Where:

I1 = fundamental current

I2 = 2nd harmonic current

I3 = 3rd harmonic current

In = nth harmonic current

Irms = RMS current
