What is the amps of a 5.5 kw 480 volt 3 phase?
Current in 200kw at 480 volts = 200,000/480 = 416.667 amps
What would full load amps be on a 480volt 90 kw electric heater be pulling 36 amps per leg?
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
How many amp in 480 vac 3- phase primary transformer if the secondary it's 120 vac?
This 480-v three-phase transformer probably has a 208-v three-phase secondary which has 120 v from each line to neutral. In that case the primary current is 0.433 times as much as the secondary current, so 100 amps in the secondary means 43.3 amps in the primary.
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.
Formula equals volts x amps x power factor x 1.732 what is 1.732?
The figure 1.73 is the results of the square root of 3. 1.73 is used in three phase calculations. The number is also used on three phase four wire systems. To find the coil voltages of a wye system 1.73 is divided by the phase voltage. An example, three phase 480 wye system. 480/1.73 = 277 volts
