How do you calculate voltage drop for starting motor current and how to get the starting pf?
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.
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.
Can a 3 phase motor be converted into a single phase motor?
A three-phase motor will not start if one or two phases aren't connected. If while running one or two phases "drop out", it will continue to run for awhile, but will eventually burn out, unless connected to a motor saver.
What is the effect of long armoured cable used for star delta starter for 3 phase ac motor?
voltage drop is be a problem.

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 condition when voltage drop occur when motor running?
its lose
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.

How do you drop the voltage of a 12v dc motor to slow it down?
Install a rheostat in series with the motor.
What is the voltage drop across each phase if a wye connected load has a voltage of 480 v applied to it?

What is the cable size for 11 kw 3 phase motor?
Incomplete data: To have an accurate result - please provide the following; 1. Voltage Rating - Low Votage or Medium Voltage Applications? 2. Efficiency 3. Power Factor 4. Distance - One way distance from source 5. Location and method and arrangement of Installation 6. Allowable or acceptable voltage drop 7. Type of cable - PVC or XLPE cable with same size has different ampacity
