Unsymmetrical fault calculations
Question 1 Question 2 Current in the neutral wire Question 3 Question 4 In the polar form , we have ER0 =100 volt = ER1 = ( 200 -j100) volt in polar form ER2 = - 100 volt in polar form Phase voltage, ER = ER0 + ER1+ER2 = 100 + (200-j100)+(-100) volt , Phase Voltage Y = angle 260 and angle -99.89 is same Phase voltage EB = ER0+aER1+a²ER2 , Question 5
