Is it possible for generators having different power factor to work together?
yes, it is possible. in fact in power systems all the generators do not run with same power factor.
Why unity power factor is used in load test?
When power factor is at unity, the voltage and current waves are aligned or in phase with one another. Since power is the product of voltage and current, power transfer is maximized at unity power factor. When power is transmitted at a lower power factor, greater current is required to deliver the same amount of power. When current is increased, the size of the transmission, distribution and generation systems, all have to be increased accordingly, along with the price of the killowatt-hour at the meter.
Why generators are rated at 0.8 lagging power factor?
Rated power factor
What is low power factor watt meter?
A wattmeter reads the true power of a load, regardless of its power factor.
Power factor formula?
Power factor is defined as the ratio of real power over total power. Total power is the vector sum of real and reactive power.
What mean power factor 0.26 lead?
When looking at power factor, it is the ratio of watts (true power) to VA. The power factor is how we measure power systems. A person with a low power factor like .26 will have a higher electricity bill.
Is it possible to measure power factor for dc system?
noAnswer'Power factor' is a quantity associated with alternating-current systems, and does not apply to direct-current systems'.
Is it possible for generators having different power factor to work together?
yes, it is possible. in fact in power systems all the generators do not run with same power factor.
What does upf stands in upf wattmeter?
UPF in a wattmeter stands for "Unity Power Factor." It refers to power factor optimization in electrical systems where the current and voltage are in-phase. This signifies efficient utilization of power without wastage in the form of reactive power.
What is the miss penalty formula used in cache memory systems?
The miss penalty formula used in cache memory systems is: Miss Penalty Miss Rate x Miss Time.
What causes low power factor?
Reactive power flow results in a lower power factor. In transmission systems, this can be due to unequal source voltages. In load networks, this is usually due to motor load.
What is power play in ice hockey?
A power play is when the opposing team has a penalty. a penalty is when you have a penalty and are trying to kill it off.

How do you save energy with power factor correction?
Power-factor correction doesn't save energy. Power-factor correction is used to reduce that magnitude of the current drawn from the supply in order to minimise the cross-sectional area of the supply conductors and associated equipment -thus keeping down the cost of the supply circuits which are owned by the supply company. Power-factor correction doesn't apply to homes, but only to larger commercial or industrial premises. The electricity supply company will negotiate a value of power factor for the load, and apply a penalty charge to the customer if his load is not kept within that agreed value.
Why unity power factor is used in load test?
When power factor is at unity, the voltage and current waves are aligned or in phase with one another. Since power is the product of voltage and current, power transfer is maximized at unity power factor.

How many KW is in 150 KVA?
It depends on the power factor, which depends on the reactance of the load.For a typical power factor of 0.92, 150 KVAR translates to 383 KVA, which translates to 352 KW.Power factor is the cosine of the phase angle (theta) between voltage and current. KVA times cosine (theta) is KW, while KVA times sine (theta) is KVAR.
