CAN 60 HZ TRANSFORMERS BE OPERATED AT 50 HZ? BASICS AND TUTORIALS


AN ANSWER TO THE QUESTION CAN 60 HZ TRANSFORMERS BE OPERATED AT 50 HZ?
Will A 60 Hz Transformers Work at 50 Hz? Answers and Links

Transformers rated below 1 KVA cab be used on 50 Hz service. Transformers 1 KVA and larger, rated at 60 Hz, should not be used on 50 Hz service due to the higher losses and resultant heat rise. Special designs are required for this service. However, any 50 Hz transformer will operate on a 60 Hz service.

Can transformers be operated at various frequencies?
A 60 Hz design is normally smaller than a 50 Hz design. For kind information please DO NOT use 60 Hz rated transformers on 50 Hz service. Without exacting designs, higher losses and greater heat rise will result. Operating 60 Hz transformers at higher frequencies may simply give less voltage regulation.

Can 60 Hz transformers be used on 50 Hz?
Yes. 60 Hz transformers can be used on 50 Hz if special precautions are taken. The change in frequency will impact the flux density of the transformer causing it to run hot, as if it were overloaded. To offset this effect, you must decrease the input voltage by approximately 17% (1/6th). This means that a transformer rated for a 480 Volt, 60 Hz input could run at 50 Hz but with a maximum input voltage of 398 volts.
