Witryna28 lip 2024 · Transformers are rated in kVA because apparent power represents the total power (current × voltage) the transformer can supply. The single-phase total full-load current is calculated by dividing the power by the voltage. For example, a 25kVA transformer can deliver 104A to a 1φ load at 240V (25,000 ÷ 240 = 104A). The … Witrynaeither the nominal power PNom is specified in active power [kW]. In this case the simulation is not dependent on the Power factor. or the nominal power PNom is specified as apparent power [kVA], so that the power limitation will occur for an active power PNom(act)[kW] = PNom(app)[kVA] * Cos(Phi). As the Pnom8limit) is lower, …

WitrynaIt works in an AC circuit. The role of Active Power is to convert Electrical Energy into other forms of energy. Reactive Power doesn’t convert energy, but it produces electrical or magnetic flux. Active power is a real power. Reactive power is a useless power. Formulas: P=I² R, P= E²/R,P=VI Cosθ. Witryna19 lis 2024 · Sure P = √3 V I Because 2500 KVA There is no active power and reactive power in the line from above. In that case, what will be transmitted from the grid is what we get. Then I = P / √3 V. I = (2500 * 10^3) / √3 * 0.4 * 10^3. I = 3608.43 A. Then select the circuit breaker 3608 A Or maybe a little more around.
