9. A substation transformer is rated 5000 kVA, 115kV:4.16kV, installed with a step voltage regulator (Type B Step-voltage regulator in Boost position). The initial sending voltage at the regulator is 120 volts (Vsend=120 v) and the voltage of load center is 109.24 volts (due to the line impedance) (Vload=109.24v). V send Vload Load Assuming the regulator has 32 steps for + 10% regulation, with 16 steps in either direction (that is 0.00625 pu voltage per step), the base voltage is 120 volts. Determine the regulator tap position that will hold the load center voltage at the desired voltage 120 volts and the regulator ratio ar
