1.73 (the square-root of 3) is the ratio of line voltage to phase voltage in a star (wye) three-phase connection, and is the ratio of line to phase current ratio in a delta three-phase connection supplying a balanced load. In each case, it is derived from the phasor addition of two values displaced from each other by 120 electrical degrees.

For voltage drop calculation you must use the current of the circuit breaker or the normal currents?
For voltage drop calculation you must use the current of the load and the distance of the load from the supply source. The circuit breaker is then used to limit the current to the rating of the wire that feeds the load.
How do you make concrete load calculation?

What is the percentage of the no-load current in a transformer to its full load current?
2 to 5% of full load current
The current load of a trnsformer is the current drawn by the?
Load!
What will happen when we change value of load resistance in transformer?
When the value of the load resistance in a transformer is changed, it will affect the current flowing through the circuit. Increasing the load resistance will decrease the current, while decreasing the load resistance will increase the current. This change in current will in turn affect the voltage across the load and the efficiency of the transformer.
What is the formula of load calculation?
There are various formula of load calculation. Power equals current multiplied by the voltage. Power can also be computed by multiplying the resistance by the square of the current.

What is the difference between rated current full load current?
rated current is the current at any given conditions......but full load current is the maximum current that the system design can hav.....it w'll b larger than that f the rated current. rated current is the current at any given conditions......but full load current is the maximum current that the system design can hav.....it w'll b larger than that f the rated current.

How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.

What is the star delta motors current calculation?
The calculation will change daily. You will have to check with the website to find out the current calculations for your needs.
Why the waveform of no load current is not sinusoidal?
No load current is mostly inductive, hence the load current may not be a sine wave
Why no load current is 5 percent of full load current in motor?
As the no load current is the current due to core losses of the motor which is very small .in no load terminals are open circuited no current flows through it, a small current flows which is due to core
What is the current for 24VAC with load of 30VA - which fuse to put in series If you can show the calculation?
I'm assuming these are RMS values. Power is equivalent to the voltage times the current: 30VA = 24*I I = 1.25A. If the load is 30VA, you should put in a fuse larger than 1.25A. If the transformer this is coming from is rated at 30VA, and the load is below this (say typically 20 watts resistive load), you may want to undersize the fuse to insure the transformer is protected.
