How do you calculate voltage drop for starting motor current
Does overload relay detect phase reversing of the 3 phase motor?
No, three phase motor overloads just monitor the motor's lines for an overload. Once detected the circuit holding the magnetic starter in will drop out and take the motor off line.
If a current of 3 A dc flows in the series field winding of your motor what wouldthe resultant voltage drop be?
The voltage drop across the series field winding of a motor can be calculated using Ohm's Law (V = I × R), where V is the voltage drop, I is the current, and R is the resistance of the winding. If the resistance of the series field winding is known, you can multiply it by the current of 3 A to find the resultant voltage drop. Without the specific resistance value, the exact voltage drop cannot be determined.
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.

What is power cable size for 1 kw 1 phase motor over 500 meters?
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
What is the acceptable percentage of voltage acceptable variance that most appliances will accept?
When doing voltage drop calculations the voltage to the connected devices should not drop below 3 % of the supplied voltage. <<>> "Most" appliances? that a tough one there is no standard. A few percent is no trouble, different appliances have different tolerances: no generalizations are possible.
Is 5 voltage drop acceptable for 480v motors?
NEC recommends a maximum 3% drop for branch circuits. 5 volts is well within this range. So, yes 5v drop is normally fine, unless the motor manufacturer has a more stringent requirement.
What is the condition when voltage drop occur when motor running?

Is a voltage drop of 0.4 volts acceptable for a 12-volt system.?
A voltage drop of 0.4 volts in a 12-volt system represents a drop of about 3.3%, which is generally considered acceptable for many applications. However, the acceptability can vary based on the specific requirements of the devices being powered and the length of the wiring. For critical applications or longer wire runs, aiming for a lower voltage drop is advisable to ensure optimal performance and efficiency.
