How do you decide KVAR rating of capacitor bank?
Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs with the load variation.If we know load factor multiply it by the sine angle which gives us the capacity of the cpapcity of the load bank.

How many vA equal to 1watt?
In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the load. For example a 100 VA load with a power factor of 0.8 (leading or lagging) will have a true power of 80 W.
What are three factor that affect creep?
Temperature, Time, and load
How do you reduce power factor value?
No-one ever aims to reduce the power factor, the ideal power factor is equal to 1, and that is the maximum possible value. A load with a power factor of 0.7 draws 40% more current along the supply wires compared to a equal-power load with a power factor of 1. That means that the power loss in the resistance of the supply wires is doubled in the case of the poor power factor. Since the supply company receives no extra revenue for the lost power, it does not like this situation and sometimes penalises users with poor power factors with extra tariffs. The power factor can often be improved by placing a passive reactor in parallel with the load to draw off the reactive volt-amps (VAR or kVAR) so that the supply wiring sees a load with a good power factor. Normally a bad load like a motor draws inductive VARs and in this case it can be corrected with a parallel capacitor that draws an equal number of capacitive VARs. Looked at another way, the added capacitor 'tunes' the load to resonate at the supply frequency.
How many amps is needed to run 3200 watts?
Watts = Amps x Volts x Power Factor For a motor the Power Factor is less than 1 and might typically be about .75. For a resistive load like a toaster PF = 1. If you know the Voltage and PF and know the wattage you can calculate amps. Amps = Watts / (Volts x PF)
How do you calculate load factor of gear box?
K Factor Also called an Overhung Load Factor. A constant used to modify the overhung load rating of a gearbox based on the type of load applied on the shaft. Use the K factor either to increase the calculated overhung load, or to reduce the gearbox overhung load rating.
How can calculate maximum demand load?
maximum demand load can be calculated as: # maximum demand=demand factor * Connected load or by # maximum demand = connected load * Diversity Factor Note: Demand factor and diversity factor are NOT same
How do you calculate the plant load factor of hydro electric power plant?
PLF of Hydal Plant - 100% or 101%
Why you take 0.95 as standard power factor?
When you need to calculate the estimated load or load current during initial design phase or so, you need to assume a value for power factor which is realistic. 0.95 is a realistic value.
If a load takes 50 kW at a power factor of 0.5 lagging Calculate the apparent power and reactive power?
If a load takes 50 kW at a power factor of 0.5 lagging calculate the apparent power and reactive power Answer: Apparent power = Active power / Power Factor In this case, Active power = 50 kW and power factor = 0.5 So Apparent power = 50/0.5 = 100 KVA
What is the other name of plant factor in load forecasting?
Load Factor
How do you calculate power load given kva?
If you multiply kVA by Power Factor (Ranges from zero to one) you get watts which is effective power.
Why the power factor improves with the load?
Power factor doesn't necessarily 'improve with the load', but it is determined by the load.
What is limit load factor in aviation?
the maximum load factor without structural damage to the aircraft. Load factor = 1 / (cos (angle of turn))
Why power factor can not be unity?
Power factor can be unity. If the load is purely resistive, then the load current and supply voltage are in phase, and the load will have unity power factor.
How the capacitor valve calculate for a for a load?
I assume that you are asking how to calculate the 'value' of a capacitor? Well, it depends what it is used for. If, for example, it is used to improve the power factor of a load, then it is first necessary to determine what the load's existing reactive power is; then, you need to know what reactive power is necessary with the power factor at its desired value; finally you need to difference between the actual and the desired values of reactive power -and this will be the necessary value for the capacitor. Power factor correction capacitors are rated in reactive volt amperes, not farads.
How many load factor equal to 1amp?
Load factor and current are not directly related
