Understanding Transformer Noise - Federal Pacific

UnderstandingTransformer NoiseISO 9001:2008 REGISTERED2 Understanding Transformer NOISEN oise is defined as unwanted sound. But, what is unwanted sound? A mel-low sound to some, can be completely unacceptable to others. Attending rock concerts with Noise levels at eardrum rattling levels is totally stimulating to many people. Put those same people in a different environment, possibly next to a Transformer , and there will be wild protestations. The difference then be-tween Noise and sound is in the ear of the hearer . Since it is necessary to place electrical apparatus alongside a wide spectrum of people we have to accept the inevitable, that even under normal condi-tions, somebody will always complain. Transformer humming has been known to soothe people (which makes it a sound) but generally it is reckoned to be a nuisance (which makes it a Noise ).

These losses consist primarily of I2R losses in the primary and secondary winding and ensure that specifications of the transformer design are met.

A transformer that is rated at 50Hz will also operate at 60Hz, however the inverse is not true: A 60Hz rated transformer cannot operate at 50Hz, unless de-rated at least 20% to allow for excessive heating effects. This is NOT recommended and these applications require a transformer rated for 50hz/60hz.
