## Which method is better to find the voltage regulation?

Which of the following voltage regulation method is accurate ? In Potier Triangle or ZPF method, voltage quantities are calculated on emf basis and mmf quantities are calculated on mmf basis. Therefore, ZPF method is most accurate among all these four methods.

## Which method gives most accurate result for voltage regulation of alternator?

Z.P.F method gives most accurate result for finding voltage regulation of an alternator.

## Which method is used for finding voltage regulation in alternator?

The various indirect methods of determining voltage regulation are, Synchronous Impedance Method or EMF Method. Ampere-turn Method or MMF Method of Voltage Regulation. Zero Power Factor Method or Potier Method.

## What is voltage regulation method?

Voltage regulation is defined as the change in terminal voltage expressed as a fraction of full load rated voltage when the load at a given power factor is removed while keeping the speed and field current constant. Voltage regulation formula, Voltage regulation = (EF – VT) / VT in P.U.

## What is EMF and MMF method?

EMF is the force that is responsible for driving the electrons in an electric circuit. Magnetomotive force is abbreviated as MMF. MMF is the driving force required to drive the magnetic flux through the circuit.
