A relação entre kW, kVA, kVAr é a mesma para qualquer triângulo retângulo. O kVA pode ser obtido tomando a tensão média para as 3 fases e a corrente média para as 3 fases, multiplicando-os e, depois, multiplicando novamente esse resultado pela raiz quadrada de 3 — que é 1,73 para um sistema de energia trifásico.

  • kVAR (Reactive Power) is the vectorial difference between kVA (Apparent Power) and kW (Real Power). kVAR calculation formula: (Reactive Power) 2 = (Apparent Power) 2 - (True Power) 2 which inturn is given as: kVAR(Reactive Power) = √ (Apparent Power) 2 - (True Power) 2 The POWER FACTOR also defines the relationship between kW and kVA. It is the ratio of kW (true power or useful power) to kVA (total power or apparent power). It is a measure of how efficiently electrical power is converted ...

Alternatively, it can also be evaluated by the formula: Average PF= kWh / kVAh Average load kW= maximum demand in kVA * Average PF. The average PF is considered as the initial power factor and the final power factor can be assumed as required. The required kVAr can be calculated from table 2. below. Table 2 KVA = SQRT (KW^2+KVAR^2) more commonly expressed S = SQRT (P^2 + Q^2) draw a right angle triangle, place S (apparent power KVA) on the hypotenus, P (real power KW) on the base line or X axis, Q (reactive power KVAR) on the quadrature axis or the Y axis and from this you can derive all the
For a given power factor and KVA (line current) the KVAR (reactive current) can be calculated as the KVA times the sine of the angle between the KVA and KW. Three phase calculations: KVA = Line Current x Line Voltage x sqrt(3) / 1000 KVA = I x V x 1.732 / 1000 KW = True Power pf = Power Factor = Cos(Ø) KW = KVA x pf = V x I x sqrt(3) x pf KVAR ... kVA is the vectorial summation of KVAR and KW. It is also called as Apparent Power or the Alternating Current (AC). It is computed by multiplying the root-mean-square (rms) current by the root-mean-square voltage.

kW = kVA = Volts x Current x 1 = Volts x Current. Summary: 1. kVA is known as the ‘apparent power’, while kW refers to the actual, or real power. 2. kW is the amount of power capable of doing work, while only a portion of kVA is available to do work. 3. kW is kilowatts, while kVA is kilo Volts Amperes. There are formulas that the calculator utilizes in performing the conversions; Calculation of Kilowatts to Kilovolts-amps S (kVA) = P (kW) / PF, which means that the apparent power in Kilovolt-amps is calculated by dividing the real power in Kilowatts by the power factor.

  • Godot animation player not playingJul 30, 2004 · 195.6 kW. If it runs at a power factor of only 0.7, that 195.6 kW load would be 195.6 / 0.7 => 279.5 kVA. You really need a proper kW/kVA meter to do this. Guessing at the power factor or the number of hours the load runs to use 46,951 kWh is just that, guessing.
