Question

Given the delta-delta system of Figure 9.5, if the generator phase voltage is 120 volts and the load
is balanced with each leg at 20 + j10 Ω, determine the line voltage, line current, generator phase
current, load current, the voltage across each load leg, and the total real and apparent load powers.

**Delta-Delta System Analysis** **Figure 9.5 Description** The diagram depicts a delta-delta connected three-phase system. It includes a three-phase generator symbol labeled "3 PH" connected to three loads, each labeled \(R1\), \(R2\), and \(R3\). Each load is connected to one of the phase lines \(L1\), \(L2\), and \(L3\), forming a closed loop. **Problem Statement** 10. Given the delta-delta system of Figure 9.5, if the generator phase voltage is 120 volts and the load is balanced with each leg at \(20 + j10 \Omega\), determine the following: - Line voltage - Line current - Generator phase current - Load current - Voltage across each load leg - Total real and apparent load power In this problem, you need to analyze the delta-delta system to compute various electrical parameters using the given phase voltage and load impedance. **Steps and Analysis** To solve this problem, follow these steps: 1. **Line Voltage:** Calculate the line voltage from the generator phase voltage in a delta connection. 2. **Line Current:** Determine the line current using the given impedance and phase voltage. 3. **Generator Phase Current:** Evaluate the current generated in each phase of the three-phase system. 4. **Load Current:** Find the current through each load resistor \(R1\), \(R2\), \(R3\). 5. **Voltage Across Each Load Leg:** Compute the voltage drop across each load leg. 6. **Total Real and Apparent Power:** Calculate the total real power (P) and apparent power (S) for the loads in the system. **Diagram Explanation:** - The left side of the diagram shows a three-phase generator with symbol "3 PH". - The generator is connected in a delta configuration. - Each load \(R1\), \(R2\), and \(R3\) is interconnected between the phase lines \(L1\), \(L2\), and \(L3\). By analyzing this diagram and using electrical engineering principles, you can determine the aforementioned parameters for the delta-delta system.
