Problem 1:

A single-phase load with a nameplate rating of 4.16kV, 2.5MW, 0.8 pf (lag) is being supplied from a 4.16kV singe-phase generator. There is a 5km transmission line between the generator and the load. The transmission line has an impedance of 0.5 / 60 ohms per 1000m.

  • What is the ratio of the voltage at the load to the voltage at the generator terminals?
  • What is the power loss in the transmission line?
  • What is the actual load power?
  • Place a 1:50 step up transformer at the generator terminals and a 50:1 step down transformer at the load (ideal transformers) and recalculate part (a) - (c).

    A 2000 V single-phase synchronous generator is being used as a backup generator outside a diagnostic center. When the generator terminals are short-circuited and a field excitation current of 2.5 A is passed, the ammeter between the terminals read 100 A of full load current. If the terminals of the same generator are opened and the voltage across them is measured using a voltmeter, we get the value of 500 V with the same excitation current. The armature resistance is...
