Power factor value varies from zero to one depending upon the angle between vectorial value of voltage & current and equals to cos fi ( where fi is the angle between i & v)
What else can I help you with?
How do you calculate power factor kvr?
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.
What is the value of 8y0 on zero as a factor?
If that's y to the zero power, the value is 8.
Of what value is the power factor?
Power factor value varies from zero to one depending upon the angle between vectorial value of voltage & current and equals to cos fi ( where fi is the angle between i & v)
Minimum acceptable value of power factor FOR LIGHTING and MOTOR CIRCUITS?
Usually for a power factor lower that 90% a service charge will be added to the monthly electrical bill. On power factor correction calculations try to get the power factor up to 95%.
What is the value of power factor for a pure capacitor?
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
What does a negative value for a reactive power means?
Meaning it's a capacitive load. Leading power factor
What is the same factor as 3 to the sixth power and What is its value?
3^6 = 729
Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
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.
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.
Is the present value factor the exponent of the future value factor?
The present value factor is the exponent of the future value factor. this is the relationship between Present Value and Future Value.
How are power factor correction units sized?
Power factor is the cosine of the angle by which the load current lags or leads the supply voltage. It is expressed as a per-unit value: e.g. 0.8; in the past it has been expressed as a percentage value , e.g. 80%.
