The transformer is a static device which transforms electrical energy from one circuit to another without either direct electrical connection. This is done with the help of mutual induction between two windings. Basically, the device is used for regulating voltage. It operates on AC supply.

There are so many types of transformers but Single Phase and Three-Phase ones are the most confusing ones. Here is the explained difference between the two.

First of all, the basic meaning of both is - A single-phase has used for increasing or decreasing the voltage connected to the primary winding. If the device is operated to enhance the voltage on its secondary winding with respect to the primary winding, it is known as a Step-up transformer. On the other hand, Three-phase transformer is the combinations of the three windings which are set-up in the manner either the first one "delta-connected" and the second one is "star-connected", or combinations like star-delta, star-star or delta-delta, which actually depends on the use of the product.

Single phase costs more than the three-phase transformers as the set up of ...
... the former one is quite bulkier whereas three-phase are easy to install which directly decreases the installation charges as well as maintenance cost and saves your pocket from having a burning hole.

As per the names both of the types are equally opposite when it comes to the weight of the two. In the other words, Single phase transformers weigh more than the latter one. This makes the installation process of the latter quite easy and handy.

With the low maintenance and installation cost, the three-phase transformers are also easy to repair; transport and most important part of the device are assembling which is also effortless.

The most convenient and strong part of the three-phase is they can also be used to provide the single power supply while it is not possible to get three-phase supply from the single phase transformers. This is the winning point for the former one.

While using single phase as three single-phase transformers, failure of one device doesn't affect the system of three. Though it is not possible in the single three-phase ones. The failing of three-phase affects its working completely.

Three-phase transformers are easy to maintain and cost less at the time of installment and repairs afterward. But the standby units of the above-said device are comparatively expensive than the single phase transformer.
