How to calculate the current? Is it power divided by voltage or kW multiplied by 2?


Ohm's law
I=U/R
Current equals voltage divided by resistance



Voltage = resistance × current and resistance = voltage: current is the derivation of Ohm's law. Ohm's law is only applicable to pure resistance circuit. The scope of application of the derivation is as follows


The application range of the derived formula is also pure resistance circuit



Power 110 kW, distance 350 meters, 95 square three core copper cable enough? What is the voltage drop?


When the power is 110KW and the three-phase voltage is 380V, the current is about 167.1a. It's enough to select 95m2 three core copper cable. For 95m2 copper cable, the DC resistance per unit length is about 0.193 Ω / km. Therefore, the DC resistance of 350m long line is about 0.068 Ω
