How much current per phase will a 18KW motor draw on 415 v?
To calculate the current per phase, use the formula: Current (I) = Power (P) / (Square Root(3) x Voltage (V)). For an 18kW motor at 415V, the current per phase will be: 18,000W / (1.732 x 415V) ≈ 24.5A per phase.
How do you calculate the phase current when working with a 10kw 3 phase electrical motor?
To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).
When connecting two alternators in parallel do the two voltages have to be in phase or directly out of phase?
When connecting two alternators in parallel, it is important for their voltages to be in phase. This means that the peaks and troughs of the voltage waveforms from each alternator align, ensuring a consistent and stable output. If the voltages are directly out of phase, it can lead to destructive interference and potentially damage the generators.
How many volt each phase in three phase?
600 volts between any two wires. The phase has nothing to do with voltages, only current relationship.
What current is drawn by a 10KVA 415V 3 Phase Load?
10000 = 415 * i i = 10000/415 = 24 a <<>> The formula you are looking for when KVA is known is I = KVA x 1000/1.73 x E = 10000/1.73 x 415 = 10000/240 = 41.6 amps.
How much current per phase will a 18KW motor draw on 415 v?

What is the Difference between single phase current and three phase current?
given a balance three phase, three wires system with star-connected load for which lime voltage is 230v and the impedance of each phase is (6+j8)ohm. find the line current and power absorbed by each phase.
What is the formula for phase angle?
Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.
What is the phase constant formula used to calculate the phase shift in a wave?
The phase constant formula used to calculate the phase shift in a wave is 2/ d, where is the phase shift, is the wavelength of the wave, and d is the distance traveled by the wave.

To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).
In delta connection what is formula for phase current?

Why current and voltages are in phase in resistor?
1) in inductor there is generation of magnetic field due to flow of current . so there is phase difference in voltage and current . 2)in capacitor there is storage of charges. there is phase diff. 3)But in case of resistor there is no such things are happend . it is only a power dissipating element.therefor there is no phase difference between current and voltage.
What is the formula to calculate ac current in single phase 240volts?
The formula is: current (in amps) = power (in watts) , divided by (240 times the power factor). The power factor is 1 for incandescent light or heaters, otherwise it can be assumed to be 0.75 for other loads.
What are the 3 phases of conditioning?
Three phases conditions are: 1. there should be three wires for carrying current and voltage. 2. the current and voltages should be sinusoidal in nature i.e A.C voltages or currents. 3. phase angle should be 120 degree apart for each line voltages or current. Suppose voltage of the first line is given by: Va= Vsin(phi) Then second and third line voltages will be: Vb=Vsin(120-(phi)) and Vc=Vsin(240-(phi)) where (phi) is the phase angle and V is the supply voltages which has same magnitude in all the three phases.
How do you calculate the resultant 3 Phase voltage when each has a different reading close to 230?
Your question is not clear.There is no such thing as a 'resultant' three-phase voltage. There are three, separate, line voltages (i.e. voltages measured between line conductors) for a delta-connected supply, which are equal in magnitude to the corresponding phase voltages. For a balanced wye-connected system, there are three line-voltages (again, measured between line conductors) which are 1.732 larger than the three phase-voltages (measured between each line conductor and the neutral conductor). For an unearthed unbalanced three-phase wye-connected load (unusual, but possible), the figure of 1.732 doesn't apply; instead the relationship must be determined by vector addition.If your question means to ask how do you determine the line voltages of a wye-connected system, given a set of unbalanced phase voltages, then you must vectorially add the relevant phase voltages to determine the relevant line voltage, taking into account the sense, or direction, of each phase voltage.
What is the RMS volts formula for 3 phase system?
In three-phase systems, we always consider individualline or phase currents, or individual line or phase voltages. In other words, we treat currents and voltages no differently from single-phase currents or voltages (i.e. we don't 'combine' them because they are three-phase quantities). So these quantities are expressed in r.m.s. values.
