A 3-phase transformer has its primary connected in delta and secondary in star. Secondary to primary turns ratio per phase is 5. For a primary phase voltage of 400 V, the secondary line voltage would be
  • a)
    2000 V
  • b)
    80 V
  • c)
    80 √3 V
  • d)
    346 V
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A 3-phase transformer has its primary connected in delta and secondary...
Primary phase voltage =400 V ;
Voltage transformation ratio,K=5
K = (Secondary phase voltage) / (Primary phase voltage) =5
∴ Secondary phase voltage = 5×400 = 2000V
Secondary line voltage √3 x 200
= 3464 V

A 3-phase transformer has its primary connected in delta and secondary...
The secondary line voltage can be calculated using the formula:

Secondary Line Voltage = Primary Line Voltage * Turns Ratio

Given that the primary phase voltage is 400 V and the turns ratio per phase is 5, we can calculate the secondary line voltage as follows:

Secondary Line Voltage = 400 V * 5 = 2000 V

Therefore, the correct answer is option a) 2000 V.
