The ratio between the number of actual turns of wire in each coil is the key in determining the type of transformer and what the output voltage will be. The ratio between output voltage and input voltage is the same as the ratio of the number of turns between the two windings.

How do you identify a current transformer and a potential transformer?
The primary winding of the current transformers has a small number of turns, whereas in potential transformer the primary winding has a large number of turns. The secondary of the current transformer has a large number of turns, and it cannot be open circuited when it is under the services.
What are the different types of transformer?
- Step up and Stepdown Transformer.
- Power Transformer.
- Distribution Transformer.
- Uses of Distribution Transformer.
- Instrument Transformer.
- Current Transformer.
- Potential Transformer.
- Single Phase Transformer.
What are 2 types of transformers?
There are two types of potential transformers; the conventional wound type (or electromagnetic type) and the capacitor voltage (potential) transformer. For voltages exceeding 100 kV (phase) the conventional type of potential transformer becomes extremely expensive owing to the insulation requirements.
How do you size a transformer?
- Transformer size is determined by the kVA of the load.
- Load voltage, or secondary voltage, is the voltage needed to operate the load.
- Line voltage, or primary voltage, is the voltage from the source.
- Single-Phase has two lines of AC power.
