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.
What else can I help you with?
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.
What is the no load current of a 90kw motor operating 440V 60Hz?
The no-load current of a motor, such as a 90 kW motor operating at 440V and 60Hz, can vary based on its design and efficiency. Typically, the no-load current for such motors ranges from 10% to 30% of the full-load current. To estimate the no-load current, you can use the formula: No-load current ≈ Full load current × (no-load current percentage). The full-load current can be calculated using the formula: Full Load Current (A) = Power (W) / (Voltage (V) × √3 × Power Factor).
What is the percentage of the no-load current in a transformer to its full load current?
2 to 5% of full load current

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.

How to do a load calculation effectively?
To do a load calculation effectively, you need to determine the total electrical load required for a building or system. This involves calculating the power consumption of all electrical devices and appliances, considering factors like voltage, current, and power factor. By accurately assessing the load, you can ensure that the electrical system is properly sized and can handle the demand without overloading.
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.

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
