Generally however, a 3/4 hp well pump will draw between 6-14 amps depending on the voltage of your power supply, which is typically either 115 volts or 230 volts in the United States. In Europe and other countries, the power supply is often either 220 to 240 volts or 380 to 415 volts. For example, a 3/4 hp well pump running at 115 volts draws Calculatethe total 3-phase power, or "Ptotal," by adding the power of each phase together: Ptotal = P1 + P2 + P3. Using the above example: Ptotal = 39KVA + 33.6 KVA + 27.5 KVA = 100.1 KVA. Convert Ptotal from KVA into Kilowatts using the formula: P (KW) = P (KVA) x power factor. Refer to operational specifications to find the power factor Theformula to convert kVA to amps in a three-phase circuit looks like this: I (A) = S (kVA) × 1,000 / √3 × V L-L(V) For a balanced load where the current is the same on all phases, the current I in amps is equal to 1,000 times the apparent power S in kVA divided by the square root of 3 (1.732) times the line to line voltage V . Thisis typically what you'll see in homes and small businesses. 120 volts and 240 volts for a single-phase, and 120, 208, and 240 for three-phase. Depending on how a transformer is wound at the service, you'll have 208/120 or 240/120, and in the case of a 3phase 4wire Delta application, you'll have 208/240/120 all in the same service. BurnedWindings from Operating on Single Phase. When one line of a three-phase power supply opens, the power becomes single phase. If this happens while the motor is running, its power output is cut approximately in half. If a three-phase motor has been submerged in water but not energized, there's a good chance it won't need rewinding 208V3 Phase Power . 208V 3 Phase power has 3 electrical legs (phases) evenly spaced in a circle (360 degrees / 3 phases = 120 degrees) around a center (neutral). Each leg (phase) provides power (phase voltage) at a unique angle (phase angle) to the center (neutral). 208V 3 Phase power also goes by the names 208V 3 Phase 4 Wire and 208Y/120V. Asthe number of power phases increases, the amount of time a given power phase is "working" decreases. For example, if you have two power phases, each phase is working 50% of the time. Add a third, and each phase only works 33% of the time, and so on. 4-Phase Example. If we assume the same components are used, then the more phases you add Tofacilitate the larger loads placed upon the newer RVs the 50 amp service was brought out. Whereas the 30 amp service was a 120 volt service yielding 3,600 watts of power, the 50 amp service is a 120/240 split phase service. The split phase service means you have two 120 volt 50 amp poles, which gives you a total of up to 12,000 watts. Thecalculation formula for three-phase power systems. To calculate the amount of power transmitted first is the equation formula, also known as Ohms Law: P= 1.73 x pf x I x V pf refers to the power factor. I refer to the current in a circuit (in amps) V refers to the voltage (in volt) Applying the Ohms law formula to calculate Power Output . #10. iwire said: Each set of phase conductors will have to total at least 1,200 amps the NEC allows a smaller neutral in some cases. For us a 1,200 amp feeder is often three sets of 600 kcmil copper. So that is a total of 12 - 600 kcmil (3A, 3B, 3C, 3N) and 3 appropriate sized EGCs for a 1,200 amp breaker.
