Question

7.A single phase transformer 2000 V / 200 V , 200 KVA has 66 turns in secondary Calculate primary turns ?

Answer 1

Answer:

single phase transfarmer has turn ratio and voltage related by-)

No. of primary turn/No. of secondry turn=primary turn voltage/secondary turn voltage

using formula-)

primary turn=66=2200/200

primary turn=66×10=660

no.of primary turn=660

Answer 2

Answer:

The number of primary turns are 660.

Explanation:

A single phase transformer uses single phase alternating current . This means the transformer is dependent on voltage cycle which operates in a unified time phase.

We know that,

$\frac{No. of primary turn}{No. of secondry turn} =\frac{primary turn voltage}{secondary turn voltage}$

Given,

secondary turns=66

primary turn voltage=2200

secondary turn voltage= 200

Now, substituting values in the formula,

Primary turns=$\frac{2200}{200} * 66$

=660

Hence 660 is the number of primary turns.
