A threephase food crusher has a power of 8kVA and a voltage of 220Volts, how many amps does the crusher have? Rta: // You must multiply initially 8kVAx1000, and the result must be divided by 220Vx√3, resulting in: 20,99Amp.

We size the overload protection per the motor nameplate current rating, not the motor Full Load Current (FLC) rating. Thus, 60A x = 75A, 70A [(A) and (A)(1)]. Motors that do not have a service factor rating of and up, or a temperature rise rating of 40ºC and less, must have the overload protection device sized at not more than 115 percent of the motor nameplate ampere rating [].

Power in hp (HP) can be calculated using the following formulas: OR HP can be converted to kilowatts as follows: HP = Kilowatts X dynamic or TwoPlane Balancing Dynamic balancing is strongly recommended in applications running at high speeds. To determine whether dynamic balancing is advisable, perform the following calculation.

• Issue ÎDuration of a high inertia load start is longer than the allowed motor safe stall time. • For these starts, thermal model must account for the current change during acceleration and also use the acceleration thermal limits for TCU calculations. • Motor thermal limit is growing along with motor rotation speed during acceleration.

but accurate calculations of load flows or short circuits analysis' would be impractical without the use of computer programs. The use of digital computers to calculate load flow started from mid 1950s. There have been ... Analysis of the Load Flow Problem in Power System Planning Studies ...

OuterVision Power Supply Calculator is the most accurate PC power consumption calculator available and is trusted by computer enthusiasts, PC hardware and power supply manufacturers across the Globe. Are you building a modern gaming PC, low power HTPC media server, or maybe you need to figure out power requirements for a rack in a data center?

Efficiency and power will need more data. Usually for small motors maximum power is at 50% of stall torque (approximately 50% of no load speed). Maximum efficiency may be 1030% of motor stall torque (7090% of no load speed).

Calculate the Apparent Power in kVA. As we can see, kVA is a much larger figure than 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 by .

for the loads: • Bus 1: Real power is 1, voltage is per–unit • Bus 2: Real power is 1, voltage is per–unit • Bus 3: Real power is .9 per–unit, reactive power is 0. • Bus 4: Real power is 1, reactive power is .2 per–unit. Note that load power is taken to be negative, for .

Power Transfer to a Resistive Load. As a general rule, the maximum power transfer from an active device like a power supply or battery to an external device occurs when the impedance of the external device matches that of the source. That optimum power is 50% of the total power when the impedance of the active device is matched to that of the load.

Although demand and energy savings were difficult to calculate because the work that M1 was performing was transferred to motor M4 in the process, M4 had capacity to absorb the load from M1. There was also potential to improve the efficiency and PF of M4 with the load addition, effectively reducing the inductive kVAR contribution of M4.

Electrical motor loads are calculated from power in kW and full rated load in is the formula how to calculate Motor loads. Example : We have 1 unit Induction Motor with 30 horsepower (hp),running with amps for amperage load and 460 volts 3 phase and power factor value is and motor efficiency is 85%

Similarly, we can calculate the annual, weeks and daily load factor. The value of the load factor is always less than 1 because the value of average load is always smaller than the maximum demand. If the load factor is high (above ), it shows that the power usage is relatively constant; if .
