LAB # 11
Single phase transformer .
Objective:
To determine the turns ratio of a transformer.
Transformer ratio(K):
The ratio by which a transformer increase or decrease the value of input voltage, number of turns of coil and current at secondary coil.
K=V2/V1 =N2/N1 = I1/I2
Lab Task
Circuit diagram for (10:1):
[pic 1]
Input value of voltage and current( V1 and I1) :
[pic 2]
Output value of voltage and current( V2 and I2) :
[pic 3]
Circuit diagram for (1:10):
[pic 4]
Input value of voltage and current( V1 and I1) :
[pic 5]
Output value of voltage and current( V2 and I2) :
[pic 6]
How to find ratio:
V1 : V2 230 : 23 10 : 1 For 10:1 | I2 : I1 23 : 2.3 10 : 1 For 10:1 |
V1 : V2 230 : 2300 1 : 10 For 1:10 | I2 : I1 2.3 : 23 1 : 10 For 1:10 |
