Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- In a balanced three-phase system, the relationship between the impedances of delta (Δ) and star (Y) connections is given by ZY = ZΔ / 3.
- This relationship applies to both magnitude and phase angle.
Given:
- Delta-connected impedance (ZΔ) = 3∠30° Ω/phase
To find the equivalent star-connected impedance (ZY):
ZY = ZΔ / 3
Substitute the given delta impedance:
ZY = 3∠30° Ω / 3
ZY = 1∠30° Ω
Therefore, the equivalent star-connected load impedance is 1∠30° Ω/phase.
