What happens when lagging Power Factor changes to leading PF?

when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.


Different types of power factor in different circuits?

The different types of power factor are: # Leading ( Due to Capacitive Circuit) # Lagging (Due to Inductive Circuit) # Unity (Due to Resistive Circuit)


Leading and lagging power factor?

The terms, 'leading' and 'lagging' refer to what the load current is doing, relative to the supply voltage (Phase difference) -never the other way around. If the current is leading the voltage, then the power factor is 'leading'; if the current is lagging the voltage, then the power factor is 'lagging'.


Which power factor is advantage lagging or leading and why?

A lagging power factor is caused by inductive reactance, which is composed of resistance and inductance -- and the resistance component lowers the supply volts. A leading power factor provides capacitive reactance that actually helps improve source voltage -- this helps motor loads run cooler.


What actually the power factor is?

Power factor is the cosine of the angle by which the current leads or lags the voltage in an a.c. circuit. It can also be defined as the ratio between a load's true power (expressed in watts) and its apparent power (expessed in volt amperes).Power factor is designated as 'leading' or 'lagging' which is determined by whether the current is leading or lagging the supply voltage. Leading currents are associated with resistive-capacitive circuits, whereas lagging current are associated with resistive-inductive circuits.


What is meant by leading and lagging pf?

Power Factor is the ratio of true vs apparent power, and comes into play with a reactive (inductive or capacitive) load. A purely resistive load, such as a light bulb or toaster, will have a power factor of 1 because the current is in phase with the voltage. An inductive load, however, such as a motor, will have a power factor less than 1 because the current lags the voltage. You could also have a capacitive load, with a power factor less than 1, but in this case the current leads the voltage.AnswerThe terms, 'leading' and 'lagging' refer to whether a circuit's load current is leading or lagging the supply voltage. Current will 'lead' in resistive-capacitive (R-C) circuits, and 'lag' in resistive-inductive (R-L) circuits. So, a 'leading power factor' indicates a leading current, and applies to R-C circuits, while a 'lagging power factor' indicates a lagging current, and applies to R-L circuits.


Power factor lead or lag?

By definition, the terms 'leading' and 'lagging' refer to what the load current is doing with respect to the supply voltage. So, for a 'lagging power factor', it is the current that is lagging.


What types of loads have a leading power factor?

Capacitive loads have a leading power factor. Current leads voltage when there is capacitive reactance. (The opposite is inductive, which is lagging.)


What determines leading or lagging power factor?

underdampedAnswerA lagging power factor describes a situation in which the load current is lagging the supply voltage. This describes an inductive load, such as a motor, etc.


Why Power factor becomes less lagging when capacitor is switched on?

Because capacitor withdraw leading current from source and net resultant become less lagging.


Why power factor lags?

When there is an inductive element in the circuit, the current lags behind the voltage. an ideal inductor will make the current lag behind the voltage by 90 degrees..a capacitive element on the other hand will make the current lead the voltage (ideally by 90deg). That's why capacitors in parallel with the system are used a lot for power factor correction


What are the advntage of the leading power factor?

A leading power factor means that the current is leading the voltage. That means that in the AC cycle (50 or 60 Hz) the current reaches its peak before the voltage. The amount of phase-lead can be up to 90 degrees which means one quarter cycle, or 5 milliseconds in a 50 Hz system.
