The zero power factor method of an Alternator is used to find which parameter or property:
- Efficiency
- Synchronous Impedance
- Paralleling
- Voltage regulation
Correct answer: 4. Voltage regulation
The zero power factor method of an Alternator is used to determine its voltage regulation.
Zero power factor method is also called the general method, the Potier reactance (or triangle) method of obtaining the voltage regulation.
