With reference to the delta-delta connection of a 3-phase transformer,...
Delta-Delta Connection Overview
In a 3-phase transformer, the delta-delta (Δ-Δ) connection has specific characteristics that influence its performance under various loading conditions.
1. Balanced and Unbalanced Loading
- The delta-delta connection is generally considered satisfactory for balanced loading.
- For unbalanced loading, the delta connection can handle it but may not perform optimally. However, it will still operate without significant issues, often resulting in harmonic generation.
- Thus, the statement "It is satisfactory for both balanced and unbalanced loading" is TRUE.
2. Third Harmonic in Output Voltage Wave
- In delta-delta connections, the third harmonic component is not present in the output voltage wave.
- This is due to the phase relationships and the fact that the third harmonics cancel each other out in the delta configuration.
- Therefore, the statement "Third harmonic does not appear in the output voltage wave" is TRUE.
Conclusion
- Given these explanations, the correct classification for the statements is:
- 1 - TRUE (satisfactory for both balanced and unbalanced loading)
- 2 - TRUE (third harmonic does not appear)
Thus, the correct answer is option 'C': 1 - TRUE, 2 - TRUE.

With reference to the delta-delta connection of a 3-phase transformer,...
Delta connection in 3ϕ transformer:
- In the delta connection, the line voltage is equal to the phase voltage.
- The line current is equal to √3 times of phase current.
- The delta-connected 3ϕ transformer can be used for both balanced and unbalanced loading.
- In the delta connection, the third harmonic component flows rounds the closed-loop of the delta.
- Hence, the third harmonic components are co-phased and hence cancel out in the line.
- So, the third harmonic does not appear in the output voltage wave.
