How do you design a transformer with three phase 400v input and single phase 2000v output?
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
What is the input current of a 150Kva 600V 3 phase transformer at 60Hz?
150000va divided by (600volts X 1.732) = 144 amps
What is the phase relationship between the input and output signals of the common collector amplifier?
Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.***********************************That is incorrect.The output of the common emitter is inverted, there is no phase shift.
What is the current of 1MVA transformer?
This depends on the voltage, and whether it is a three phase or single phase transformer.

What will be input and output current of 10 KVA 3 phase UPS?
It will depend on input & output voltage, if voltage is same current will remain same

What is phase in current?
Phase applies only to AC current and not DC current. Reactive components - inductors and capacitors - in a system will result in the system output either lagging or leading (capacitance lags and inductance leads). If we apply an AC signal to the input of a system, we can observe the input and the output on an oscilloscope. If the system lags then the output signal will appear to be shifted to the right relative to the input singal, and vice versa for a system that leads. Since AC signals are periodic we think of one period as being 360 degrees (or 2*pi radians). The phase of output signal relative to the input signal is thus measured in degrees. For example: An AC signal of period of 10 seconds and a peak current of 2A is applied to the input of a system. The output is measured and it is found that the output current peaks 3 seconds after the input voltage - so the output lags the input, meaning the circuit has a capacitive reactance. What is the phase of the output relative to the input? Since T=10 and the phase difference in seconds is 3 the solution is simple: 360 / 10 * 3 = 108 degrees So; the output lags the input with a phase difference of 108 degrees.

What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
What is kva rating of single phase transformer?
This is the rated output of the transformer, obtained by multiplying the rated secondary voltage by the rated secondary current. And it's 'kV.A', not 'kva'.
How many amps does a 208 volt 3 phase 45 kw hot water heater draw?
45000 / 208 /sqrt(3) = 125A per phase this is probably called a boiler unless it has a 2000Gallon tank
What is the input current of a 150Kva 600V 3 phase transformer at 60Hz?
150000va divided by (600volts X 1.732) = 144 amps
How do you calculate primary AC for 3 phase ac input if output load dc current is known?
DC Current divided by 1.225
What is a full load current in single phase transformer?
It is the rated maximum current that can be taken from the transformer. This is equal to the VA rating divided by the output voltage. So a 6 kVA 240 v transformer would have a maximum current rating of 6000/240 or 25 amps.
