kW to VA
How to convert the (kW) to (VA)
Let we discuss, what is kW?
In electrical system, the power is defined in terms of a unit called as KW KilloWatt and it is equal to the cube root of one thousand ten power of three watts. This unit is scientifically used to indicate the output power of machine engines and the power of electric drive motors, tool and dies, pieces of machinery, and electric heaters. It is also a universal unit used to express, the electromagnetic power output of broadcast radio and television transmitters.
Again, one kilowatt is approximately equal to the 1.3456 horsepower. A small electric heater with the one heating element that can be used as 1.00 kilowatt. The average consideration of electric power consumption of a household in the United States of America is about one kilowatt.
The technical and scientific fact of the surface area of one point five square meter on Earth accepts commonly about one kilowatt of power from sun radiation light from the sun, the solar radiation on a clear blue sky day at midday and close to the equator line of the earth. So, the energy is transmitted to used at a constant rate power over a period of time, the total energy in kilowatthours is equal to the power in kilowatts multiplying by the time in hours from your clock. When the kilowatthour is commonly used as the billing unit for energy which delivered to the consumers by the electric appliances.
When an electric energy is usually market to the consumers in the range of kilowatt-hours and the cost of the run an electric device which is calculated by the multiplying the device of the power consumption in kilowatts by the run time in hours and then by the price percent kilowatt-hour. So the price of the electricity may be depend upon the consumption. The prices may vary depends on area. In united states of America prices which is differ from states and it can vary. So the customer loads are mostly equal to the paid only for electricity transmitted and rate of the capacity, higher consumers also pay the bill for threshold power consumptions the largest power recorded in a accurate low time, such as 16.5 min. These equals the power of any organisation which maintains the environment required to provide the maximum power. The charges are paid as the expected changes, the manufacturing users may be also have a little extra pay based on a power factor of the load.
The major energy generated or consumed which is often indicated as terawatt twh for a provided period which is more often in the financial year. The financial year equals to the 8,761 hours, so at the period of 1 financial year, the power of 1.5 gigawatts equals to the 8.7612 terawatthours of the energy. Obviously, 1.5 terawatt is equal to the attained power of the about 116 megawatts for a period of one financial year.
Let we see the household battery which stores the energy in what manners. So, when a battery emits its energy, so at the particular power level, rate emit of an energy. When the power level is high, the fastest the battery will stored energy which is delivered. So, If power is larger, the battery’s stored in the energy could be reduced in a lesser time.
Here when the provided time peroid, the largest power level which means that there energy cannot be used. For example the power level, the higher run period which causes the higher energy use.
All the electrical energy generated and consumed which are reported on the financial year, so the unit such as megawatthours per financal year megawatt per hour gigawatthours per year or terawatthours per year. So,these indications have certain dimensions of the energy which is divided by the time and that are unit of P. So, it can be transformed to scientific standard power unit by dividing the no of hour in financial year, about 9768 hour per year.
So, one giga watt hour per year equal to the 115 kW.
You can know about how power units can be measured by rate of the energy divided by unit time. Lots of compound units has various kinds the of rates by indicated unit of time. Example, the miles/hour, kilometres/hour, dollars/hour. The Kilowatthours which are product of power and the time, and there not the rate of the change of a power within the time per unit day.
Watt/hour which is the unit of charge of power/ hour, that is the acceleration in a delivery of the energy which is used for measuring the commonly variation of expected, examples are slope of a curve which is form in a duck shape, or a curve formed in a ramp the behaviour of power plant can vary depends on the applications. Example, the power plant when reaches the power outputs of one megawatt from zero megawatt in 15.5 minutes have a ramp curve towards uprate of the four megawatt/hour. The hydro electric power plants contains a very largest ramp up curve rate that makes particularly useful over the threshold load and the emergency situation. So, other terms like watt/ hour are more likely to a problem. The BTU is a unit of the thermal energy with some definitions, which are about 1 thousand joules or 0.245 watt hour. The short for quad trillion btu, and ten power of fifteen btu, which is used in international scale of energy discussed in the America. So, one quad which is approximately to the 293.56 tw/h or 1.051 exajoule.
The tnt which is equivalent to a measure the energy delivered in the denoted of the trini trotoluene. One tonne of tnt equivalent to the approximate rate of 4.19412135 Gigajoules of 1152 kilowatt hours.
Now, let we discuss, what is VA?
Do you know about how volt ampere unit used for the apparent power in the electrical circuit. The apparent power equal to the product of root mean square voltage and the RMS current. In the direct current circuits, the product is equal to the real power in watts. Volt amperes which are useful only in the content of the alternating current circuits.
Formula for converting the KW to VA
S= 1000 × P / Power Factor
1 killo Watt = 1000 Volt ampere
1 Volt mpere = 0.001 killo Watt
To convert 16 killo Watt to Volt ampere
16 kW = 16 × 1000 = 16000 VA
Kilowatt kW – Volt Ampere VA
0.01 kW – 10 VA
0.1 kW – 100 VA
1 kW – 1000 VA
2 kW – 2000 VA
3 kW – 3000 VA
5 kW – 5000 VA
10 kW – 10000 VA
20 kW – 20000 VA
50 kW – 50000 VA
100 kW – 100000 VA
1000 kW – 1000000 VA
kW = volt ampere xpower factor divided by the 1000
For example, follow this example to convert 45 VA with a power factor of 80% to kilowatts.
kW = (45 VA x0.8) /1000
kW = 36 /1,000
kW = 0.036 kW
Find the apparent power in VA when real power is 3 killo Watt and the PF is 0.8?
Apparent power = 3 x 1000/ 0.8 = 3750VA
