The video explains the concept of Wye-Delta circuit, where source is connected in Wye configuration and load is connected in delta configuration. Concept is emphasized by solving problems.
Example 12.3: A balanced abc-sequence Y-connected source with
is connected to a -connected balanced load per phase. Calculate the phase and line currents.
Practice Problem 12.3: One line voltage of a balanced Y-connected source is Vab =120 angle 20 . If the source is connected to a -delta connected load of 20 angle 40.
find the phase and line currents. Assume the abc sequence.

Sir parhaaty ap bhi slides se hain par apko slides se parhana aata hai atleast reading nhi krte ye bat achi hai

[@musfiqurrahman2982]

why cannot you write that line current =phase current aftrer convertting delta part into wye ? though you are working with wye and finds line current using single phase analysis but for phase current you have used relationship of line current and phase current?

[@ElectricalEngineeringAcademy]

The question is actually asking for phase current of delta load. What we calculated is Phase current (= line current) of Y load (this was done for ease of calculation). So we need to convert I(phase-y) to I(phase-delta).

[@musfiqurrahman2982]

@@ElectricalEngineeringAcademy ohhh,so can I use this method in every Y-delta connection for finding line current and phase current?

[@ElectricalEngineeringAcademy]

Yes. Watch this kzbin.info/www/bejne/onebi5Kfr62bbaM

A balanced three-phase star connected source having a line voltage of 208 V rms supplies a three phase balanced delta connected load. The total power delivered to the balanced delta connected load is 1200 W with a power factor of 0.94 lagging. Determine the required load impedance for each phase of delta connected load and resulting line current. Can you help me solve this problem?

[@ElectricalEngineeringAcademy]

from (pf)power factor (=cos theta) calculate theta = 20 degree (approximately). Real power per phase is 1200/3 = 400W. Real power 400=Vline x I line x pf /under root3. so Iline =3.54 A. I phase = Iline/underroot3 = 2.05A. Magnitude of Zdelta = Vphase/Iphase = Vline/I phase = 208/2.05 = 101.46 ohm. Z delta = 101.46

11:53 isn't Ib supposed to be -90 + (-90) = +150 and Ic supposed to be -30

[@ElectricalEngineeringAcademy]

Yes there is an error in Ib, the angle should be -90 + (-120) = -210 degree. Ic is ok (120 +(-90) = 30), unless you want to use -240 degree option; in that case angle will be -330 degree ( which is equal to +30 (by adding 360 to -330)). Thanks.
