These are two different values. kWh is the amount of kW that are used in an hour. To convert kW to kva use the same formula but leave out the pf (power factor) component.
AnswerFirst of all your should realise that power is measured in watts (or kilowatts), not in kilowatt hours! A kilowatt hour is an unit of measurement for energy, or work done, NOT power! So your question doesn't actually make any sense!
Furthermore, a kilovolt ampere is the unit of measurement for apparent power, and it should be written as 'kV.A', not 'kva'.
So you cannot convert energy in kilowatt hours to apparent power in kilovolt amperes, as we are talking about two completely different quantities! It's like asking "How do you convert miles into kilometres per hour?" That's what I mean by your question not making any sense!
The first answer needs correction, as the kilowatt hour is not 'the amount of kilowatts used in one hour'. You do not 'use' kilowatts, as kilowatts is simply a rate. So the correct definition is that a kilowatt hour is the amount of energy used in one hour, at the rate of one kilowatt.
5kw = 6.25 kva becoz kva = kw/ pf if we take pf is o.8
The meter shows the load has a very poor Power Factor of about 30%. It appears this service has a very large capacity -- most of it not used. Taking one or more (like for X-Ray or similar machine) transformers out of service may help improve PF.
Your question cannot be answered, unless the power factor of the load is specified. Since true power(measured in watts) is the product of apparent power(measured in volt amperes) and the power factor of the load.So, given your figure of an apparent power of 20 kV.A(not 'kva'*), the corresponding value of true power could (theoretically!) range from20 kW at a power factor of 1.0, to0 kW at a power factor of 0.(*The correct symbol for kilovolt ampere is 'kV.A', not 'kva', and the correct symbol for kilowatt is 'kW', not 'kw'.)
Some more information is needed. 100% power factor for one hour and 220 volts = 22 kva. At 0.85 power factor = 22/0.85 = 25.88 kva
To determine the KVA needed to run a 55 kW motor, you can use the formula: KVA = KW / Power Factor. Assuming a typical power factor of 0.8 for motors, the calculation would be KVA = 55 kW / 0.8 = 68.75 KVA. Therefore, approximately 68.75 KVA is needed to run the 55 kW motor. Adjust the power factor accordingly if you have a specific value for your motor.
To convert from KVA (kilovoltamperes) to KWH (kilowatthours) first convert to KW (kilowatts) by multiplying by power factor. Power factor is the cosine of the phase angle between voltage and current. Then multiply by the number of hours that you run the load.
To convert 'kwh' to 'kvah' you first need to measure the length of time. You will then convert this amount to hours by dividing by 3,600. You will then divide this amount by the length of time.
To convert 2 kW to kVA in single phase, you need to know the power factor. If we assume a power factor of 0.8 (common for many single-phase loads), the conversion formula is kVA = kW / power factor. Therefore, for 2 kW at a power factor of 0.8, the result would be 2 kVA / 0.8 = 2.5 kVA.
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
You cannot convert them. KVA is a measure of power, while amperes are a measure of current.
You must know the current or resistance to convert voltage to power.
To convert kilovolts (kV) to kilovolt-amperes (kVA), you need to know the power factor of the system, as kVA accounts for both voltage and current in an AC system. Without a specified power factor, you cannot directly convert kV to kVA. However, if you assume a power factor of 1 (which is ideal), then 80 kV would be equal to 80 kVA in a purely resistive load scenario.
There is no difference in the meaning of kWh or KWH. Both forms of writing kWh mean "kilo watt hours," and the format acceptable to most in the technical community is "kWh."AnswerThe correct symbol for kilowatt hour is kW.h.
KVA is the unit for the apparent power i.e it's the vector sum of the true power in KW and the reactive power in reactive volt-amperage. So, to get the value of the KVA for the 30KW,just divide the active power(30kw) with the power factor of that load.
It could be as much as 63 kW (63,000 Watts) into a load with a power factor of 1.0. For other loads, multiply the kVA by the power factor.
To convert kilowatts (kW) to kilovolt-amperes (kVA), you can use the formula kVA = kW / power factor. If we assume a typical power factor of 0.8, 360 kW would be approximately 450 kVA (360 kW / 0.8 = 450 kVA). If the power factor is different, you would need to adjust the calculation accordingly.
To convert kilovolt-amperes (kVA) to brake horsepower (bhp), you need to consider the efficiency of the system. Since kVA represents apparent power and bhp represents mechanical power, the conversion will depend on the power factor of the system. Typically, you would need to know the power factor to accurately convert between the two units.
