How much current will flow in neutral line for three phase supply 100amps?
If all three legs of the system are balanced then zero amps will flow all the way up to 100 amps if only one leg of the three phase system is used. The neutral in a wye three phase system carries only the unbalanced current. This is why in services for a three phase four wire system you are allowed to reduce the size of the neutral conductor.
How many amperes for 3 phase 220v 5 tonner?
50 Amps Single Phase 20 Amps Three Phase
How do you convert single phase kva to three phase kva?
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
Convert 250 kilowatts to amps with 460 volts 3 phase?
You have to know the power loading and phase angle (or power factor) between each pairh of the phases, otherwise you could be making serious errors.
How do you convert kvar to amps?
At what voltage? When you know the voltage then, to get the amps those kilovolt.amps contain, you simply divide the kilovolt.amps by the voltage. <><><> You can't convert kVA (kilovolt.amps) to amps unless you know either the source voltage (as was explained above here in the first answer) or the load resistance which is drawing the current from the source. If you know them both you can use Ohm's Law to get the amperage: I = V / R In words, Ohm's law is: Current (amps) equals voltage divided by resistance (ohms)
How do you convert kva to amps three phase system when you have 220-240 volts?
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
How much current will flow in neutral line for three phase supply 100amps?
If all three legs of the system are balanced then zero amps will flow all the way up to 100 amps if only one leg of the three phase system is used. The neutral in a wye three phase system carries only the unbalanced current. This is why in services for a three phase four wire system you are allowed to reduce the size of the neutral conductor.
What is conversion of 4.6kva to kw?
Single-phase, 2.5 amps; three-phase 1.443 amps.
How many amps does 42kw in a 3 phase system 120208 convert to?
You would use the 208 voltage which is a three phase voltage, the 120 volts is each leg to ground or star point. The formula for Amps = kw x 1000/1.73 x Volts x pf. Pf = power factor.
How many amperes for 3 phase 220v 5 tonner?
50 Amps Single Phase 20 Amps Three Phase
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
How di you convert kw to amps for a one phase system?
A kw (kilowatt) is 1000 amps x volts. If you assume your one phase system has 120 volts, then divide by 120. Cheap, but close enough for most work, assume 100 volts, then each amp is a tenth of a kilowatt.
What is 7kva in amps?
In a standard 3 phase system in North America, 7kVa would be equivalent to 19.5 amps on each phase. The equation is: 7kva*1000/208v/1.73=19.45 amps (3 phase)
How do you convert single phase kva to three phase kva?
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
How do you convert 208 v 2160 Amperes to KVA?
To convert amps to kVA, you use the following formula: Amps = (kVA x 1000 / voltage) / 1.73
How do you convert AMPS to KVAs?
A rough guide is to divide kVA by the supply voltage then multiply by 1000 to get current in Amps. E.g. 20kVA divided by 120V is 0.167; times 1000 is 167 Amps. But kVA is not the same as kW, so more information is needed before equipment is used.
How do you convert 400 amp of three phase supply into kwh?
By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.
