Given:
- Two transformers operating in parallel
- Impedance of the first transformer = 6%
- Impedance of the second transformer = 4%
- Total load supplied by the combination = 100 A
To Find:
- Current supplied by the 6% impedance transformer
Solution:
Step 1: Calculate the total impedance of the combination.
- Impedance of the first transformer = 6%
- Impedance of the second transformer = 4%
The total impedance in parallel combination can be calculated using the formula:
1/Z_total = 1/Z1 + 1/Z2
Where Z_total is the total impedance and Z1, Z2 are the impedances of the individual transformers.
Substituting the given values:
1/Z_total = 1/6% + 1/4%
Now, convert the percentages to fractions:
1/Z_total = 1/0.06 + 1/0.04
Simplifying the equation:
1/Z_total = 16.67 + 25
1/Z_total = 41.67
Z_total = 1/41.67 = 0.024 Ω (approximately)
Step 2: Calculate the current supplied by the 6% impedance transformer.
Using the formula:
I1 = (V_total) / (Z_total)
Where I1 is the current supplied by the 6% impedance transformer and V_total is the total voltage supplied by the combination.
Since the total load supplied by the combination is 100 A, the total current (I_total) can be expressed as:
I_total = I1 + I2
Where I2 is the current supplied by the 4% impedance transformer.
Given that the total load supplied by the combination is 100 A, we can write:
100 A = I1 + I2
Substituting the values:
100 A = I1 + (100 A - I1)
Simplifying the equation:
100 A = 100 A
Therefore, the current supplied by the 6% impedance transformer (I1) is 40 A.
- Two transformers operating in parallel
- Impedance of the first transformer = 6%
- Impedance of the second transformer = 4%
- Total load supplied by the combination = 100 A
To Find:
- Current supplied by the 6% impedance transformer
Solution:
Step 1: Calculate the total impedance of the combination.
- Impedance of the first transformer = 6%
- Impedance of the second transformer = 4%
The total impedance in parallel combination can be calculated using the formula:
1/Z_total = 1/Z1 + 1/Z2
Where Z_total is the total impedance and Z1, Z2 are the impedances of the individual transformers.
Substituting the given values:
1/Z_total = 1/6% + 1/4%
Now, convert the percentages to fractions:
1/Z_total = 1/0.06 + 1/0.04
Simplifying the equation:
1/Z_total = 16.67 + 25
1/Z_total = 41.67
Z_total = 1/41.67 = 0.024 Ω (approximately)
Step 2: Calculate the current supplied by the 6% impedance transformer.
Using the formula:
I1 = (V_total) / (Z_total)
Where I1 is the current supplied by the 6% impedance transformer and V_total is the total voltage supplied by the combination.
Since the total load supplied by the combination is 100 A, the total current (I_total) can be expressed as:
I_total = I1 + I2
Where I2 is the current supplied by the 4% impedance transformer.
Given that the total load supplied by the combination is 100 A, we can write:
100 A = I1 + I2
Substituting the values:
100 A = I1 + (100 A - I1)
Simplifying the equation:
100 A = 100 A
Therefore, the current supplied by the 6% impedance transformer (I1) is 40 A.
