Zero
power factor method for an alternator is generally used to determine
Efficiency
of alternator
Synchronous
impedance of alternator
Voltage regulation of alternator
All
of the above
Voltage regulation of alternator
The
Zero Power Factor (ZPF) method is used to determine the voltage regulation of
alternator (synchronous generator). This method is also known as Potier method.
Hence,
the correct option is (C).
