Hi, Help me with this circuit question
Question 3. The two parallel loads in the figure shown below are as follows. Load 1 absorbs 24 kW and 12 kVAr and Load 2 consists of a 60 ohms resistor in parallel with a capacitive reactance of 480 ohms. 1. Determine the rms magnitude of the generator voltage Vg if the load voltage Vo is 2,400 volts rms. 2. With Vo as the reference, draw a phasor diagram of the system voltages. 8 + j10 Ω + V₁, L₁ L2

R 20 B Y R 20 400V, 60Hz B IR ZB = 55 < 0° 0 Figure 4: Star Unbalanced Load IR ZR IB ZY ZR = 30 < 0° 0 Fault Zy17 <0°02 = A balanced load with ZR = ZB Zy = ....<00 Q was supplied a three phase 50 Hz, 100 V between line (balanced source). A fault on phase 'B' causes an open circuit, which unbalanced the load as shown in Figure 4. Similarly, a fault on the load of phase 'Y' cause a short-circuit, which unbalanced the load as shown in Figure 5. Using complex notation determine and analyse the individual phase currents and the neutral current in both figure.

I am having a hard time understanding this problem set. I cannot seem to get my calculations right.
The power customer has four circuits of220-volt three phase. The circuits have the maximum demand as follows: Circuit no 1 = 35 Amperes Circuit no 3 = 72 Amperes Circuit no 2 = 46 Amperes Circuit no 4 = 57 Amperes The diversity factor is 1.5, the load factor is 50% and the power factor is 80%. Determine the maximum KVA demand of the customer? A. 46 B. 80 C. 26.5 D. 53 The answer here is letter D but I dont know its solution

Consider a simple positive phase sequence, three-phase, three-wire system operated at 50 Hz and with a balanced load. Each phase voltage of 240 V is connected across a load composed of a series-connected 80.00 and 500 mH combination. Please report your answer, so the magnitude is positive, and all angles are in the range of negative 360 degrees to positive 360 degrees. Calculate the total power supplied by the three-phase source. (Round the final answer to three decimal places.) W. The total power supplied by the three-phase source is
