Current (I): Enter the the current in Amperes (A). 3 phase KW = Amps x Volts x 1.73 x pf/1000. Where V L is the RMS value of the applied line voltage and P.F. The current in 1 φ circuits is a ratio of 1000 times kVA to voltage. The current which can be supplied by a three phase 50kVA generator when connected 240 volt single phase is determined as follows: Note that for 3-phase power calcs the quick way in your head, it's not necessary to put sqrt(3) in anywhere. Single phase KW = Amps x Volts x pf/1000. S (kVA) = 0.746 x P (HP) / pf. Formulae. Calculator-1 Input the system line-line voltage, line current, and power factor angle (degrees) into Calculator-1 to compute three-phase reactive power, real power, and total power as well as the power factor. For any three-phase AC circuit, Current, I = 1000 x kW / (√3 x V L x P.F.) Line (DOL) start. Converting kVA to kW kVA = kW: Converting kW to kVA kW = kVA: Converting kW to HP kW = HP: What size genset is needed to start a 3 phase electric motor Direct on . For single phase kVA calculations or conversions we need to know two of the three values of kVA, Volts and Amps. The following formula calculates total power in a three-phase system based on KW and KVAr or voltage and current. Hp to kVA Conversion Formula: Hp is the unit of active power and kVA is the unit of apparent power. Amps per Phase. It is computed by multiplying the root-mean-square (rms) current by the root-mean-square voltage. KVA = VA / 1000 KVA = E x I / 1000 Amps = KVA x 1000 / Volts KW(kilowatts) = Voltage x Current x Power Factor / 1000 KW = E x I x PF / 1000 VA = voltage x Current x 1.73 VA = E x I x 1.73 Power(watts) = Voltage x Current x 1.73 x Power Factor W = E x I x 1.73 x PF KiloWatts (1000 watts = 1 kW) kW. Ampere (Volt-Amperes or Current) I. Volts. The most important thing to consider when sizing a generator is the high inrush currents associated with starting electric motors and transformers, which are typically six times the full load current.

Expedited Shipping - US & Canada 800-853-2073. Three-Phase Power Formula. This is because the current for an equivalent kVA, single phase is much higher than for a three phase. As a sanity check, I tend to think about it the other way around - 10kVA from a 400/230V 3-phase supply is the same as three 3.33 kVA single phase loads - so 14.49A per phase (at 230V). Three-Phase Power Equations - Electrical 3-phase equations; Tag Search . Power Factor … HOME; INVENTORY. The formula to convert kVA to amps in a three-phase circuit looks like this: Current (A) = Power (kVA) × 1,000 √3 × Voltage (V) So, amps are equal to 1,000 times the power in kVA divided by the square root of 3 (1.732) times the voltage. Converting Amps to Watts and VA in 3-Phase Power In three phase power, the basic equation is multiplied by the square root of 3, or 1.732 So VA = V * I * 1.732 W = V * I * 1.732 * PF Thus a 3-phase motor running at 6 amps and 460 volts would require 5000VA Example: Electric furnace 50 KW, 208 V, 3 phase I = KVA = KW = (P.F.=1.0) = 50KW = 144.3Amp .20KV√3 Example: Motor 10 HP, 460V, 3 phase, find I NEC 430-150, 10 HP @ 460V, 3 phase I = 14 Amp 3.
