ABSTRACT
The performance of any machine can be analyzed with reference to parameters like power factor, total harmonic distortion, voltage regulation, etc. These parameters alter when a machine is subjected to different loads. Depending on the load connected to the system, the voltage and current waveforms are varied. Due to the effect of harmonics, distortion of waveforms from sinusoidal to non sinusoidal is c ....etc

THEORY:
The regulation of a 3-phase alternator may be predetermined by conducting the Open Circuit (OC) and the Sort Circuit (SC) tests. The methods employed for determination of regulation are EMF or synchronous impedance method, MMF or Ampere Turns method and the ZPF or Potier triangle method. In this experiment, the EMF and MMF methods are used. The OC and SC graphs are plotted from the two tests. The synchronous impedance is found from the OC test. The regulation is then determined at different power factors by ....etc
