Can we improve generator power factor for increasing active power?
Wiki User
∙ 11y ago
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.

What are the factor affecting voltage build up of dc generator?
List the factors that affect the voltage building in D.C generator.
Is the active power supplied to a motor affected by placing of capacitor in parallel with the motor?
No. The capacitor may improve its power factor by altering the effective reactive power of the machine, thus reducing the current drawn from the supply.
What is the effect of inductive load in distribution system?
Inductive load where current lags voltage to keep the power factor low thus increasing the consumption of more electrical units of supply provider. This is since an inductive load draws reactive power as well with active power. Reactive component is watt less power drawn from the source. We use only active part of the source. But pays from active+reactive parts. This low power factor also effects the other systems in the circuit virtually making the cables under sized by heating them
What is the formula of active power?
For a single-phase system, active (or 'true') power is the product of the supply voltage, the load current, and the power factor of the load.
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.
How do you increase voltage in a generator?
At least to a certain extent, by increasing the field current. Or In Real Power Plant they decrease the power factor to increase the voltage.
When synchronus generator is supplying active and reactive power it is operating at leading or lagging power factor?
A synchronous generator is operating at lagging power factor (positive P & Q) when it is supplying P & Q to the system. P & Q are positive which means that they are flowing away from the bus where the generator is connected (overexcited case). On the other hand, it is operating at leading power factor when it is supplying P and absorbing Q. The sign of Q is negative which means that it is flowing towards the generator bus (underexcited case).
What is the function of capacitor in an electric generator?
In an electric generator, the function of a capacitor is to provide reactive power and improve the power factor of the generator. When a generator is connected to a load, the load may have a combination of resistive, inductive, and capacitive components. Inductive loads can cause the power factor of the generator to decrease, resulting in lower efficiency and voltage regulation. By adding a capacitor in parallel with the generator, the reactive power generated by the capacitor can offset the reactive power of the inductive load, leading to improved power factor correction. This helps to enhance the efficiency of power transfer and stabilizes the voltage. The capacitor absorbs and supplies reactive power, reducing the strain on the generator and ensuring a steady and efficient supply of electrical energy.
What is the significance of the rotation of a generator?
The significance factor of the rotation of a generator is, that this rotation is what governs the frequency output of the generator.
What is meant by Generator P.f?
the cosine of the angle between voltage and current of generator is called power factor (pf) of generator.
What method improve power factor?
The most common method of improving the power factor of a load is to connected a capacitor or capacitor bank, of appropriate reactive power (expressed in reactive volt amperes), in parallel with the load.
Increasing the temperature of a blackbody by a factor of 3 will increase its energy by a factor of?

What are the factor affecting voltage build up of dc generator?
List the factors that affect the voltage building in D.C generator.
What are the factors effecting improve your economy?
There are several factors that can improve the economy. The biggest factor that can improve and economy is a low unemployment factor. When unemployment is falling the economy usually improves.
How you can improve craft paper burst factor?
To improve the burst factor of craft paper, you can consider increasing the thickness or weight of the paper. Additionally, using higher quality fibers or adding a coating can enhance the paper's strength and toughness. Proper storage and handling to prevent damage and maintaining optimal moisture levels can also help improve burst factor.
Can you use capacitor for diesel generator set in running condition?
DG set is designed for 0.8 lag power factor. if it fall below this, we can used proper rating capacitor to improve this. what happens if we run the DG at .6 pf
What is a factor that prevents a population from growing?
Weather is a factor that prevents a population from increasing. Or the term for it is called Limiting Factor
