The voltage and current will give the kVA, but the kW depends on the power factor of whatever load is connected to the supply.
For a (let's say) 11 kV supply, the voltage from line to neutral is 11,000/sqrt(3) which is 6351 v. The kVA on each phase is 6.351 times the current, and you just add up the three kVA values to find the total.
At higher voltges like 11 kV the three currents in the lines are usually very nearly equal.
What else can I help you with?
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.
What phase current is flowing in a balanced purely resistive 480V 3 Phase Delta connnected system with a demand of 96KW?
96 kW means 32 kW from each phase. If the load is star connected each resistor has 277 volts across it and carries 32,000/277 amps, 115.5 amps. The load resistors are 277/115.5 ohms or 2.40 ohms If the load is delta connected each resistor has 480 volts across it and carries 66.7 amps. The load resistors are 480/66.7 ohms or 7.20 ohms. In both cases the line current is 115.5 amps.
How many amps can you draw from a 25kva 3 phase step down transformer?
For practical purposes, transformers do not lose power during transformation. Thus, if you have the VA of the transformer, you can simply divide the VA by the voltage to get a rough idea of maximum current. In a real application, the maximum amperage will be dependent on the phase angle of the transformer.
How do you measure RLA on a 230-1 phase motor do you add each the amps measured on each leg?
You can't measure an RLA. It is determined by the factory that manufactured the compressor. To answer your other question, a 230 volt load is actually using both legs as part of the circuit, so you can measure either leg with a current meter but there is no need to add them up.
How do you calculate how to split a 7.5Kw load over 3 phases?
A 7.5 kW three phase load will be balanced by the manufacturer. When connected to a three phase source the line current on each phase will be equal.
How do you calculate 1 phase kWh from measuring amps on each phase?
Measuring the current in each phase (or do you mean 'line'?) will not give you sufficient information to work out what you are asking for.
If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?
Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.
How many amps on 3 phase 225 amp panelboard each phase?
In a three-phase 225 amp panelboard, each phase will carry 225 amps. This means that the total current flowing through the panelboard is distributed evenly across the three phases, allowing for a maximum of 225 amps on each phase at a time.
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 many amps are available in a three phase 225 amp panel?
In a three phase 225 amp panel, there would be a total of 225 amps available for each phase, making it a total of 675 amps for all three phases combined. This means that you could have up to 225 amps of current flowing through each phase simultaneously.
How many amps does 30KW strip heater draw at 208 volts 3PH?
Assuming it is a 208-volt line voltage (as normal in 3-phase) the phase voltage is that divided by sqrt(3), or 120 volts. Each phase has to supply 10 kW so the current on each phase is 83.3 amps.
What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?
Yes, for a 15HP 3-phase 415V AC motor, each phase will draw approximately 26 Amps of current when running under normal operating conditions. This results in a total current draw of 26 Amps per phase for the motor.
In a residential 200amp service is 100 amps the maximum that each of the two phase conductor can transmit or can they both carry 200 amps?
Each hot leg to the neutral wire of the service has the ampacity of 200 amps, that is why 3/0 wire is required. A 3/0 copper wire with an insulation factor of 90 degrees C is rated at 210 amps.
How many amps does a 2000 watt heater draw at 240 volts on each line?
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
How do you measure amps from a 3 phase motor?
thong each wire using amp meter
How many amps per leg can you pull on a 50 amp 3 phase connector?
On a 50 amp 3 phase connector, you can pull 50 amps per leg. This means that each of the three phases can carry up to 50 amps individually, resulting in a total capacity of 50 amps per leg.
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.
