Describe the 3 phase star - delta motor circuit with circuit? please don't use Al answer I will dislike

Please, I do not want a theoretical solution or using artificial intelligence. I want a solution on paper using the mathematical laws of the topic

Draw the per-phase equivalent circuit of a three-phase squirrel-cage induction machine. List all of the elements in the equivalent circuit and briefly state their function

Q9. What is the basic principle that a cage winding can be represented by a three-phase winding? Give your explanation.

Find the following : 1.Ripple Voltage (vpp) 2. Zero-to peak ripple(Vop) 3.secondary winding of the transformer high line and low line

Show me how is solution will be if fualt happened before transformers or in one of generator

The step down DC chopper uses DC source voltage V(dc) = 200 V and resistive load impedance of 10 ohm. The duty cycle is 0.4 the voltage drop across the switch may be taken as zero, Calculate :   (a) Average and RMS value of output voltage.  (b) Average and RMS value of output current.

Fundimentals of Energy Systems Q8

How can we solve this question by using inversion formuler like using the poles

The one-line diagram of a simple power system is shown in Figure below. The neutral of each generator is grounded through a current-limiting reactor of 0.25/3 per unit on a 100-MVA base. The system data expressed in per unit on a common 100-MVA base is tabulated below. The generators are running on no-load at their rated voltage and rated frequency with their emfs in phase.
