![]() Example: A 50 kVA single-phase transformer has a 4000 V primary, and a 400 V secondary. 1 BTU (British thermal unit) = Watts x 3. The transformer calculator uses the following formulas: Three Phase Transformer Full-Load Current (Amps) kVA × 1000 / (1.732 × V) V voltage (volts).Watts = Voltage (root-mean-squared) x Amps (root-mean-squared) x Power Factor (PF) (a three-phase circuit would multiply the voltage by the square root of 3 or approximately 1.732).Some Useful Conversion Factors and Formulas Single Phase Amps to kVA Examples (1) When Current (i) 2 & Voltage (V) 4. The resulting real power is 450 kilowatts. Most Uninterruptible Power Supply (UPS) units will list the average power factor and real-time load capacity of the UPS, in addition to the KVA.Įxample: You own a 500 KVA UPS unit (apparent power) with a 0.9 power factor. In the case of a 0.5 power factor, real power is approximately half that of the apparent power.ĭeploying systems that have higher power factors result in less electrical loss and can help improve your Power Usage Effectiveness (PUE). In the case of a 1.0 power factor, the real power equals the apparent power. ![]() The power factor is a ratio (a number from 0 to 1) of real power and apparent power. The resulting inefficiency of electrical transmission can be measured and expressed as a ratio called the power factor. ![]() Differences between real and apparent power, and thus watts and volt amps, arise because of inefficiencies in electrical transmission. However, as waves of current and voltage coincide less, less real power is transferred, even though the circuit is still carrying current. When the voltage and current of a circuit coincide, the real power is equal to the apparent power. Real power is the amount of actual power that can be drawn from a circuit. On the other hand, a watt (W) is a measurement of real power. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. Once the download completes, the installation will start and you'll get a notification after the installation is finished.Have you ever wondered why some power ratings are expressed in WATTS, some in AMPERES or AMPS, some in VOLTS, and some in KVA? This page will explain in simple terms the difference between the power ratings and describe when each should be used in your data center and network architecture planning.Ī KVA is simply 1,000 volt amps. kVA Calculator will be downloaded onto your device, displaying a progress.A pop-up window with the permissions required by kVA Calculator will be shown.Tap on the Install button located below the search bar and to the right of the app icon.
