Thanks...but i want to know the loss in voltage is because of voltage drop? or is it because of the current drawn by the load?

its coming out as 4.5Volts...so i want to know if the rest of the voltage is lost in voltage drop? or is it because of the current that the load on the secondary that is withdrawing. thanks

When we take down voltmeter readings from the terminals of a Rectifier (rated 12V), we get the voltmeter reading as 4.5V. Does that mean the rest of the voltage is lost in the form of voltage drop? or is it because of the current drawn by the load? I would be glad if someone could please post...

20 x 30 = 600?? is that how the whole current flow to the main should be calculated?

Alirght thanks for the heads up..If possible can you please provide me with any tutorial on how cable sizing calculations are done?? I work in UAE in an oil and gas Engineering company. Thanks in advance

Thank you sparkey...I will study the chart you provided.

Thanks Berkeman...But i want to learn the complete step by step calculation done in (for example oil & gas industries) to prepare cable sizing documents... majorly with a 3phase voltage of 415V...

Can someone please guide me (with an example if possible) on Cable Sizing Calculations. I want to learn the step by step procedure alongwith calculations that are performed during the preparation of Cable Sizing Documents. Thanks in advance!
