Extracted text: Q3) A 3-phase transmission line, 10 km long consists of three solid copper conductors are arranged at corner of an equilateral triangle of 0.5m side. Load conditions at receiving end are 5 MW at 0.8 power factor lagging, 11 kV, 50 Hz. The efficiency of transmission is 90.9% and the resistivity of copper is 1.7774*10° 2.cm. Calculate: i) The sending end voltage and power factor. ii) The voltage regulation of the transmission line.
