Voltage Drop Calculation and Cable Sizing

As per standards voltage drop at the terminals during normal operation should be below 5% and during start up it should be 15%.

Voltage drop during normal operation- (mV/amp/m x Full load current x length in m)/100.

Voltage drop during start up- (mV/amp/m x (6 xFull load current) x length in m)/100.

mV/amp/m- This parameter is available in manufacturer cable data sheet and in catalog.

The % Voltage drop should not exceed the above mentioned % limits, in such a way cable core area should be selected.

let me give you some information.

You need to hire an engineer to do the calculations for you.

so you have 150 kilowatts required for the motors, can you see in the dark? does the pump house have lights, does it have power points etc etc. we will say yes like most buildings. so we will call it 160 kilowatts, so we already know you are going to need a pole mount transformer outside the property, and as you cannot possibly be an engineer, then you will be required also to have the transformer cabled to the property. Your job is done. you do not have the legal licencing to perform this job at pole connect or you would not be asking the question, so when you get a quote to get the transformer put up and the cable installed they will ask how much power you will be using and they will calucalte it for you. you don't even need to know. If you have access to this level of power, then no one here should be helping you endanger lives if you are not qualified, sorry but ther is no reason you should be told. Even a half smart person would know there is a faster way to find that out rather than ask on here. If you are a student with an assignment, you are not learning anything by asking for the answer.
