Question

One of the world’s largest electric arc furnaces is in Turkey, claims the transformer manufacturer Alstrom Grid in 2012. Power transformer has 300MVA power conversion capacity with 34.5kV to 1200Vrms conversion specs. If 1200V power output is carried to the 100m away furnace with 100mm pure Cu wire (?=0.05µ?/ 30cm, find power loss through Joule heating. Calculate the temperature of the wire using Stefan-Boltzmann law (?=6x10 -12 W/?K4cm2 and radiated power P=AJ*=A??T4 and take ?=1)
