According to (2), rectifiers for telecommunication power supplies with BE circuits are graded in 7 classes that permit total input current harmonic distortion of less 60%, 45%, 35% and 10%. The 2-20 JkVA ratings that can be connected to 400 V call for harmonic distortions less than 45% and 35% for the line input current at 3-25 kVA. Ratings up to 50 kVA may generate harmonics of 10% maximum or they must be connected to a separate medium-voltage transformer.
