### Three-Phase Power Problem Analysis**Problem Statement:**A balanced 3-phase Y-connected source with a voltage of 866V and frequency of 60Hz feeds a Δ-connected load (Zph = 177 - j246Ω) via a line. Each phase of the line has an impedance of 1 + j2Ω. The phase sequence is positive. We need to determine the following:1. Line and phase current2. Power absorbed by the load3. Power dissipated by the line**Circuit Diagram Explanation:**The provided circuit diagram illustrates the connections and components of the three-phase system:1. **Source:** - The source has three lines labeled \( a, b, \) and \( c \), each providing a voltage of 500∠0° V, 500∠120° V, and 500∠-120° V respectively.2. **Line Impedances:** - Each phase of the line has an impedance of \(1 + j2Ω\).3. **Load:** - The load is Δ-connected with a phase impedance of \(177 - j246Ω\). The voltages across the load are denoted as \( \vec{V}_{AB} \), \( \vec{V}_{BC} \), and \( \vec{V}_{CA} \). - The current through each phase of the load is denoted as \( I_{AB} \), \( I_{BC} \), and \( I_{CA} \).4. **Points of Interest:** - Voltages and currents are annotated with both their magnitudes and phase angles at various points in the circuit. - The notation \( \vec{I}_{na}, \vec{I}_{nb}, \) and \( \vec{I}_{nc} \) represents the line currents at points \( a, b, \) and \( c \).### Solution Steps:1. **Line and Phase Current:** - Calculate the line currents using Kirchhoff's laws, Ohm's Law, and the impedance of the line and load.2. **Power Absorbed by the Load:** - Use the formula \( P = \sqrt{3} \times V_{LL} \times I_{L} \times \cos{φ} \) to calculate the power absorbed by the load, where \( φ \) is the phase
