Fill in the hp of the motors in their starting sequence, select. How to convert 1,000kwh to kva assuming the power source is at 380volt, 3phase, 50hertz and power factor at 0. You only need to fill in the columns colored in orange. To get the answer you just have to take the kva and multiply them by the power factor, as follows.
Power calculator, convert kva to kw, kw to kva, watts and. Vehicle category unit test cycle directive europe cohc nox pmhc nox nox hc pm co nox hc 560 kw gkwh 5,00 1,30 9,20 0,54 3,50 1,00 6,00 0,20 3,50 4,00 0,20 3,50 4,00 0,025 iso 8178 c1 200426 eec. Scan across the row to the right until the three phase ll line to line voltage being utilized column is reached. So kilowatts are equal to kilovoltamps times the power factor. The first thing to enter the value of the kw you want to convert, then you must enter the power factor, if you do not know you can see in the tables above the most common values, finally you must click on calculate, if you need to do another calculation must click on restart. It therefore follows that a kilowatt kw is the same as a kilovoltampere kva, with each side of the equation divided by 1,000. A preliminary study to determine the amount of continuing education credit to award for home study. Convert nms to kilowatt conversion of measurement units. Threephase systems and kilounits in alternating current ac power systems, voltage is often delivered in phases, as this is advantageous in terms of reducing energy losses. Power calculators for quick electical generator power consumption, sizing, and unit conversion. Basic electrical power fundamentals load reference kilowatts kilovolt amps power factor pf motors kw kva use nec 430148 kw kva. The real power p in kilowatts kw is equal to the apparent power s in kilovoltamps kva, times the power factor pf.
Horse power hp, watts, kilowatts, kw, kva, kilo volt amps, volts, amps, amperes, power factor, pump hp, fan hp. It is given as the absolute value of the cosinus of the phase angle between the current and voltage. To find the phase current rating if the 50hz load kw or kva is known, select the known kva or kw rating on the chart above. Convert kw to kva, kva to kw, voltage, kw to hp, and more to assist with generator sizing and electrical specifications required for your genset. Pf is the power factor and depends on the used electrical device.
