When two alternator running in parallel the power factor from 8 drops to 5 or less why is it so?
power factor 0.8 drops to .05 when two alternator running in parallel
What is the relation between power factor and frequency for purpose of parallel operation of alternator?
No relation is there power factor is a unit less quantity.
Why a rotor of an alternator at rated power dissipates more heat at a low power factor load than at a high power factor load?
at lower power factor current drawn by load is high and at higher pf the current drawn is less...
What affect does a leading power factor have on alternator generator excitation currents?
When a leading power factor load is applied, the voltage of the genset or genset bus rises, and the voltage regulation system reduces exciter power, reducing the strength of the magnetic field. If the field fails, the generator set may slip a pole, which results in potentially catastrophic alternator damage. pawan
How does form factor affect emf in alternator?
The form factor in an alternator refers to the ratio of the root mean square (RMS) value of the output voltage to its average value. A higher form factor indicates a waveform with more peaks and a higher RMS voltage, which can enhance the efficiency of power generation. Conversely, a lower form factor may lead to lower effective voltage output, affecting the overall electromotive force (emf) produced. Thus, optimizing form factor is essential for maximizing the performance of an alternator.

Why alternator power factor 0.8?
In terms of generators, the alternate power factor is generally 0.8 for most models. This factor is defined as the power needed to operate within the limits of he generator capability curve.

Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
How do you calculate the size of a car power inverter to power a small space heater?
Regardless of the size needed by the heater, the car's alternator will be the limiting factor. If you oversize the inverter to more than the alternator can handle you may burn out the alternator. Heaters consume allot of amperage.
Why occ curve and zpf of an alternator have similar shapes?
The OC (Open Circuit) curve and ZPF (Zero Power Factor) curve of an alternator have similar shapes because they represent the variation of terminal voltage with respect to the field current and power factor, respectively. Both curves show the relationship between these parameters and the ability of the alternator to generate voltage under different operating conditions. This similarity in shape is due to the fundamental characteristics of the alternator's design and operation.

What are the disadvantages of leading power factor on generator supply system?
in case of leading power factor the air gap flux inside the alternator will increase which may cause over heating of the stator end coil and overhang portions.
Why the value of power factor should be low?
no.... the power factor of any machine should be as near as to 1 when the power factor becomes near to 1 there is no need to the alternator to supply the reactive power.. but in general all most all the loads in the power system inductive in nature the power factor is becoming lagging(<1) so to avoid this the power generating companies and the govt. are recommending the people to have the capacitors at the load ends....... since the capacitive reactance can nullify the effect of the inductive reactance this will try to improve the power factor

Is an alternator part of power train?
No, an alternator is not part of the power train. It is an auxiliary to provide electricity.
