BALANCED DELTA-DELTA CONNECTION
A balanced Δ-Δ system is one in which both the balanced source
and balanced load are Δ-connected.
phase voltages for a Δ- connected source are the ff:
Vab = Vp∠ 0°
Vbc = Vp ∠ -120°
Vca = Vp ∠ +120°
phase currents, are the ff:
IAB= VAB/ ZΔ= Vab/ZΔ
IBC= VBC/ ZΔ= Vbc/ZΔ
ICA= VCA/ ZΔ= Vca/ZΔ
line currents are obtained from the phase currents by applying the KCL at nodes A, B, C:
Ia= IAB- ICA Ib= IBC- IAB
Ic= ICA- IBC
Example
Problem: Three 230-V generators form a delta-connected source that is connected to a balanced
delta-connected load of ZL = 10 + j8 Ω per phase as shown in Fig. 12.52.
(a) Determine the value of IAC.
(b) What is the value of Ib?
Solution:
It is better explain ,and add some example
ReplyDeleteIt is better explain ,and add some example
ReplyDeleteWhat about currents in ab, bc, and ca?
ReplyDeleteWow , perfect
