## What is a secondary transformer?

A secondary winding is the winding of a transformer that receives its energy by electromagnetic induction from the primary winding. The secondary winding is facilitated with larger-gauge wire because of the increase in current, whereas the primary winding is made up of smaller-gauge wire due to less current conduction.

## What is primary voltage transformer?

Primary voltage is the voltage applied to the terminals of the primary winding of a transformer. … If the primary has fewer turns than the secondary, you have a step-up transformer that increases the voltage. If the primary has more turns than the secondary, you have a step-down transformer that reduces the voltage.

## What are the two main 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.

## What is main part of transformer?

There are three basic parts of a transformer: an iron core which serves as a magnetic conductor, a primary winding or coil of wire and. a secondary winding or coil of wire.

## What is the secondary current?

(Elec.) a momentary current induced in a closed circuit by a current of electricity passing through the same or a contiguous circuit at the beginning and also at the end of the passage of the primary current.

## What is secondary voltage formula?

Solve the equation Vs/Vp = Ns/Np where Vs is the secondary voltage, Vp is the primary voltage, Ns is the number of secondary windings and Np is the number of primary windings. Divide the number of secondary windings by the number of primary windings, and multiply the source voltage by this ratio.
