EPRI Chapter Test Questions with Verified Solutions If a generator is producing 500MW and 200Mvar, the generator is: Lagging 87 Is the IEEE device number for a differential relay. Can a Synchronous machine have a negative torque angle? What doies this mean? Yes, the machine is absorbing active power. A customer load is fed at 12o Volts. The customer's voltage is doubled while the load magnitude stays the same. What effect does this have on the power losses? Decreases the losses by a factor o...
