Hi.

Can u pl explain hot to calculate current rating of bus bar. and pls share the formula.

Zeeshan

Please provide an example… unable to understand that how to use..??

Hi. How to calculate the drop voltage for 25mm2 cable three phaze +earth . 350m 4 A

RJ Ordonez

there’s no unit for power on the spread sheet. is it in kva or kw? thanks!

Dear sir,

I ask you what is the bus bar calculation formula?

In case of Busbar voltage drop calculation you take Resistance=0.005 ohm and reactance=0.011 ohm . what is the reference of these values. have any international code ? also how can i get a cable resistance and reactance ?

Marvin

Very useful..Thank you very much..

thanks.but i don’t understand the way to calculation. please help?

Ronald Acuavera

please advise and calculate, i have 5x1250Amps,.8pf, 220v gensets, synch to a common busbar, and two outgoing CB’s of 2500A, what will be the main busbar rating.

NAGARAJ123

IN BUSBAR TRUNKING SYSTEM HOW DO YOU CALCULATE THE KA RATING OF THE BUSBAR. FOR EXAMPLE IF CUSTOMER ASKS US TO GIVE 50KA WITH 50x10mm ALLUMINIUM OR COPPER BUSBAR WHAT IS THE FORMULA WE HAVE TO APPLY PLEASE SOME ONE WHO KNOWS ABOUT HIS GUIDE ME

Edvard

Customer normally shouldn’t ask you this, but to tell you the ratings of loads, so you can calculate the CBs in incomers and outgoing cubicles, as well as rating of main horizonal busbars. When you have all these information, you can calculate short curcuit withstand current on busbars.

Eng. Bo.7sn

I entered the results but I didn’t know what is sin(phi) so i put it =0

and the results below:

——————————————-

Selected BusBar is Correct

3.92 (Within Limit)

What is the size of the bus bar ?
