WebQ (VAR) = 3 x V (P-V) x I (A) x sin(φ). Convert Amps to kVAR: Reactive power Q (kVAR) in Kilo Volt Amp reactive is equal to the 0.001 times of line current I (A) in amps and the line voltage V (V) (For three-phase, you have to consider 1.732 times of the Line voltage) and the sine of power angle.. Power angle can be calculated from the power factor by using …
WebJun 5, 2010 · The power in a 15 MVA (15000 KVA) transformer depends on the power factor. You did not specify the power factor, so I will assume a power factor of 0.92. Simply multiply MVA by PF and you get 13.8 MW. WebFeb 2, 2024 · PF is the power factor and equals cos φ. Here, φ is the phase angle — the angle of lead or angle of lag of the current's phase with respect to the voltage's phase. We can therefore calculate the active power using the two phases as: P = V ph × I ph × PF; Or, in terms of line voltage and line current: P = √3 × V line × I line × PF
