What will happen when diesel genertor set run on more inductive load?
There is no problem using a generator to run more inductive load so long as the generator capacity can supply the needed power to the inductive loads. The inductive loads should not be switched on at the same time but there should be a little delay before another load is switched ON as inductive loads draw more power at start ON. The power factor of the inductive loads also affect the generator, hence for safe operation a power factor that is approaching 1 is desirable. Ogu Reginald Ekene
What is the difference between an inductive and a capacitive load?
Resistance load it means there is passive load to impede current flow. Inductive load means there is a coil as a load while still a passive it has its own characteristics which differs from a resistive load which is linear while inductive is not linear load
Why most of the practical loads are inductive?
Most loads are actually resistive, such as an incandescent (normal) light bulb or electric heat or cooking equipment. Other loads are mostly inductive because they incorporate either transformers or motors, which are both inductive. Off hand I cannot think of a normally capacitive circuit, which would be the opposite of inductive.
What is non-inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
Power factor correction capacitors?
Yes, they exist. Capacitors are often used to change a low power factor (such as 0.5) to a higher power factor near unity (1). In some instances, this will lower fees and costs to utilities. In homes, this is not really necessary as most devices used in homes are near unity power factor, or tend to be minor/sporadic loads (such as a washing machine).
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.)

How do you calculate the amperage given the watts and voltage?
Amps = Watts / (Volts x Power Factor). The Power Factor is one for resistive loads and decreases for inductive loads like motors.
What the reason of getting minus power factor reading?
its nothing but a lagging powerfactor...its due to inductive loads......
Causes of low power factor methods of improving power factor?
using highly inductive loads may lead to reduction in the power factor. or consumption of unappreciable amount of power also results in the same. methods to improve PF . using synchronous condensers using capacitor banks using ow inductive loads
What is ac1 and ac3 contactor?
AC-1This applies to all AC devices (Resistive loads) with a power factor of at least power factor of 0.95 AC-3This applies to AC Inductive loads. Like squirrel cage motors.
Why you are using capacitor banks to improve power factor?
A poor power factor is caused by inductive loads or electronic devices. These loads cause excess current to flow in the circuit reducing the efficiency. Inductive devices are considered to be a "load" for reactive power. Reactive power does not actually do any real work by is required to develop magnetic fields. Capacitors are considered to be "sources" of reactive power. So these capacitors will supply the reactive power to the inductive loads instead of the utility supplying this power. This is why capacitors are used to improve a poor or low power factor. This is just a very brief description on this topic. Power factor correction is becoming a very complex topic with more and more poor power factor loads being used every day.
Why natural trend to lagging power factor?
Power factor is the cosine of an AC circuit's phase angle, where the expression phase angle is the angle by which a load current lags or leads the supply voltage.Lagging phase angles and power factors occur in resistive-inductive circuits. Leading phase angles and power factors occur in resistive-capacitive circuits.Most industrial and commercial loads are combinations of heating (resistive) loads and motor (inductive) loads -in other words, resistive-inductive loads. Accordingly, lagging power factors tend to be more common than leading power factors.

How many watts 24v 2.9a?
24 x 2.9 x Power Factor. Power Factor equals 1 for a resistive load and decreases toward zero for various inductive loads.
What is non inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
