Question

As depicted in Figure 9.3, a 3-phase Δ connected generator feeds a Y connected load. The generator
phase voltage is 120 volts and the load consists of balanced legs of 5 Ω each. Find the voltage across
each load leg, the line current, the line voltage, the generator phase current and the total load power.

### Electrical Engineering Problem: Analysis of a 3-Phase System

#### Problem Statement:
As depicted in Figure 9.3, a 3-phase Δ (Delta) connected generator feeds a Y (Wye) connected load. The generator phase voltage is 120 volts and the load consists of balanced legs of 5 Ω each. Find the voltage across each load leg, the line current, the line voltage, the generator phase current, and the total load power.

#### Figure 9.3 Description:
The diagram in Figure 9.3 shows the circuit configuration:
- A three-phase Δ connected generator with phase voltages denoted as E1, E2, and E3.
- The generator supplies power to a Y connected load, represented by resistors R1, R2, and R3, each with a resistance of 5 Ω.
- Points a, b, c represent the generator terminals, while points x, y, z denote the load terminals forming the neutral point.

#### Analysis and Calculations:
1. **Voltage Across Each Load Leg (Line-to-Neutral Voltage):**
   In a Y connected load, the line-to-neutral voltage (also known as phase voltage) is the same as the generator phase voltage.
   \[
   V_{ph} = 120 \, \text{V}
   \]

2. **Line Voltage:**
   The line voltage in a Y connected load is given by the relationship:
   \[
   V_{L} = \sqrt{3} \times V_{ph}
   \]
   Therefore,
   \[
   V_{L} = \sqrt{3} \times 120 \, \text{V} \approx 207.8 \, \text{V}
   \]

3. **Line Current (Current through Each Resistor):**
   The line current can be found using Ohm's Law:
   \[
   I_{L} = \frac{V_{ph}}{R_{L}}
   \]
   Substituting the given values:
   \[
   I_{L} = \frac{120 \, \text{V}}{5 \, \Omega} = 24 \, \text{A}
   \]

4. **Generator Phase Current:**
   For a Δ connected generator, the phase current is related to the line current by:
   \[
   I_{ph} = \frac{I_{
