How do you calculate the turns ratio of a single-phase transformer?

The turns ratio of a single-phase transformer can be calculated using the formula:

Turns ratio = Nā / Nā

Where:

Nā is the number of turns in the primary winding (input side) of the transformer.
Nā is the number of turns in the secondary winding (output side) of the transformer.

To find the turns ratio, you need to know the number of turns in both the primary and secondary windings. Typically, this information is given in the transformer's specifications or can be measured directly in practice.

Here's a step-by-step guide on how to calculate the turns ratio of a single-phase transformer:

Identify the primary and secondary windings: Determine which winding is the primary (input) and which one is the secondary (output). The primary winding is usually connected to the power source, while the secondary winding supplies power to the load.

Count the number of turns in each winding: Use a coil winding count or consult the transformer's specifications to find the number of turns in the primary (Nā) and secondary (Nā) windings.

Calculate the turns ratio: Divide the number of turns in the primary winding (Nā) by the number of turns in the secondary winding (Nā). The result will give you the turns ratio of the transformer.

Example:
Suppose you have a single-phase transformer with 300 turns in the primary winding and 150 turns in the secondary winding.

Turns ratio = Nā / Nā
Turns ratio = 300 / 150
Turns ratio = 2

In this example, the turns ratio is 2:1
