How to calculate the load of a running factory. The factory has different capacity machines, lighting , Utility.otheritems.I have 400killwatt transformer how much it can carry the the load.and if the machine is carrying total 300 amps load that means the amps will be devided in each phase?

You simply sum up the power of each running machine (in KW) to get a total spending power of the factory. To provision the transformer you should use the worst case - the maximum number of machines running at the same time.

What fernando said is true, but you have to figure start up amps. Sometimes a motor uses a lot more amperage just to get it started. So the power will have a peak at the beginning of a shift when all the motors are turned on. A lot of companies will stagger the time that motors are turned on because the electric company charges a 'demand' charge. A demand charge is based on peak amount of energy used.
