    our first frequency range starts at 50Hz and ends at 2 kHz or 2.5 kHz. For 60 Hz networks, the range goes from 60 Hz to 2.4 kHz or 3 kHz. From the end of the harmonics range to 9 kHz, we have a frequency range that is not currently regulated. We will come back to this in the “Power quality” chapter. Above 9 kHz, the high-frequency range starts.

  • Which Transformer is More Efficient When Operates on 50Hz

    In addition, if T/F is not designed to be operated on both 60 and 50 Hz, the more current will flow in case of 50Hz transformer with leads in higher power loss due to “I 2 R losses”. This is due to the the following reasons: When frequency (f) decreases, Inductive reactance (X L) decreases (X L ∝ f).
