Using the above example: Ptotal = 39KVA + 33.6 KVA + 27.5 KVA = 100.1 KVA. Given the kW and power factor the kVA can be easily worked out. I1, I2, I3 = current of phase 1, phase 2 and phase 3 in ampere (A) The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V): The power P in watts (W) is equal to the You’ll see the three-phase voltage comes out to. Both provide the generator with three times their nominal current to cover inrush peaks from the electrical motor, for a minimum duration of ten seconds, via a residuary excitation current. It has three text fields which help in determining the exact units you require after the conversion. reset. The real power P in watts (W) is equal to square root of 3, multiplied by the power factor PF, multiplied by the phase current I in amps (A), multiplied by the line to line RMS voltage VL-L in volts (V). For three-phase AC circuits where the line to line voltage is known, the formula to convert watts to amps is: I(A) = P (W) V L-L (V) × PF × √3 The current I in amps is equal to the power P in watts divided by the line to line voltage V in volts multiplied by the power factor PF multiplied by the square root of 3. U = voltage in Volt (V) Wattage of a three phase load is then calculated as watts = volts x amps x 1.73. Air conditioning efficiency : EER, SEER, and COP conversion. All rights reserved 2015-2018. The power taken by a circuit (single or three phase) is measured in watts W (or kW). To calculate kVA, you need to enter the known values of voltage and the current into the respective fields. The current is simply the kVA divided by the voltage. * Use e for scientific notation. Pt = total power of the circuit in watt (W) P1, P2, P3 = power of phase 1, phase 2 and phase 3 in watt (W) V = voltage in Volt (V) exemple : V1=230 V in 400 V three-phases circuit I1, I2, I3 = current of phase 1, phase 2 and phase 3 in ampere (A) Cos φ1, Cos φ2 , Cos φ3 = cosinus phi of each phase (without unit) © Same thing for each phase… It can either be direct current, denoted as (DC) or alternating current (AC). Refer to operational specifications to find the power factor associated with the system. You can start by selecting the type of electric current. It is a standard unit of power and energy. GENERATOR AMP RATINGS - THREE PHASE EXTENDED: 3 PHASE AMPERES - 80% POWER FACTOR* (Extended Table) kW Times 1000 divided by (Volts*1.73) *.80. About | 1 watt is defined as the energy consumption rate of one joule per second. I = current in ampere (A) It is a unit of electric current equal to a flow of one coulomb per second. Line to neutral voltage P(W) = 3 × PF × I(A) × VL-N (V) If you want to know the power consumption in watts for an appliance with a current of 3 amps and a voltage of 110, your calculation would be: Amps ⨯ volts = watts 3 ⨯ 110 = 330 watts. time value below (number of hours and days the appliance is running) : P=U*I*cosφ How to use the watts to amps calculator? PF times the phase current I in amps (A), times the Real Power. Quick VA to Watts calculator with step by step formula and conversion explanation. Cos φ1, Cos φ2 , Cos φ3 = cosinus phi of each phase (without unit), Hydropower, hydroelectricity online calculation, Power, voltage, current calculator, 1-phase or 3 phase. power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V): The power P in watts (W) is equal to square root of 3 times the power factor How the electric utility industry generates and delivers power to its customers covering Basics, Delivery, Safety and Generation. Mathematical equation: Two-phase Amps = [HP * 746] / [E * %age Efficiency * PF * 2] Example: Determine the current flowing through a two-phase, 0.5 HP, 220 volt motor having an efficiency rating of 90% and a power factor of 0.92. I AC1 Ø =Current/Ampere 1 phase. Imagine that we want to know the power of a current with 15 amps and a three-phase alternating current, line-to-neutral voltage, with the amplitude of 100 volts (in other words, what is the result of conversion 15 amps to watts for VLN equal 100 volts). Watts to Amps calculator It is used to convert the electric power in watts (W) to the current in amps (A). Three phase kW to Amps. Converting Watts to Amps (AC three phase system) Line to Line Voltage: Calculate the phase current I in amps (A) by dividing the power P in watts (W) by the square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V): (The power factor is the ratio of the real power flowing to the load to the apparent power in the circuit.
