Systems involving single phase transformers have power lines as the input source. However, they only need one primary and one secondary winding to facilitate voltage transformation. They are available in various models with varying features in terms of mounting type, horsepower range, dimensions, taps, shipping weight, and kVA.
With systems involving three phase transformers, the power is produced by the rotation of three coils or windings through a magnetic field inside the generator. These windings are spaced hundred and 120 degrees apart and produce power as they rotate through the magnetic field. The power that is generated from this system is distributed to three separate lines, and thus identified as three phase power.
Three phase transformers can only work properly if they have three coils or windings attached in proper order to correspond with the incoming voltage. The transformer transforms the incoming voltage to the required voltage level while also retaining proper phasing and polarity.
Three Phase Industrial Applications
Three phase electricity is the best and most efficient Avenue for powering industrial loads. It can facilitate the smooth operation of heavy-duty equipment since voltage can be transmitted over long distances with the smaller conductor. If single phase power is required, two phases of the three phase system can be used to harness the power. In some situations, single phase power can be applied between the ground and only one phase.
Single phase power is:
3-phase power is:
Single phase transformers may for three phase applications in one of the following ways:
