WebFeb 20, 2024 · The fact that source voltage and current are out of phase affects the power delivered to the circuit. It can be shown that the average power is Pave = IrmsVrmscosϕ, thus cosϕ is called the power factor, which can range from 0 to 1. Power factors near 1 are desirable when designing an efficient motor, for example. WebJul 1, 2003 · The formula for real power (P) in a 3-phase systems is as follows: Using this formula yields the output and input currents of the drive: The drive input current from the supply is more than 5% lower than the drive output current to the motor. The active power input, instead, is 1.2kW higher (58.3kW vs. 59.5kW) than the output from the drive. WebFirst, we need to calculate the apparent power in kVA. We can do this by multiplying load voltage by load current: As we can see, 2.308 kVA is a much larger figure than 1.5 kW, which tells us that the power factor in this circuit is rather poor (substantially less than 1). Now, we figure the power factor of this load by dividing the true power ... portofino island resort coupons
