THIS FORMULA DIFFER ACORDING TO LENGTH OF TRANSMISSION LINE: FOR SHORT TRANSMISSION LINE IT IS                                                    V (DROP)=Iz   Z   IS impedance   and it is for single phase so, for balance 3-phase it s multiple of three

Hi Jennifer,

               Hru?I m searching 4m few days,but didn't get anything about calculation of electrical equipments like busbar,MCB,MCCB n all.

Will u plz do me a favour,will u plz mail me that site n books name with ISBN no.

I m thankful.

who can tell how to wire a motor

[admin]

yes i can

Hi, rumora

You may be use Dialux Software

[admin]

The input is 35 KW ,3 phase voltage is specified.We ned to calculate resistance of cable conductor /Km & apply the fourmula of

Receiving end Power = sending end power   ( 35 KW) – ( power Losses in conductor /cable+ shut capacitence impedence along the O.H.line for 35 Km),Gives you the answer.It will decrese if you use 440 Volts ,if transmit same through 3.3 KV it will increases,as per my little knowledge goes.

this information is very informative for all electrical engineer and electric lover, thank you for sharing.

Hi,  In situations like this, I would always use a Stainless steel cabinet with Rittal type SK Stainless steel Rain hoods over SK fan / filter units.  You will need to work out the airflow for the enclosure based on the heat rejection value from the Variable speed drive you are using.

 

The rain hoods slide up to gain access to the filter unit for maintenance, this should also stop any salt water spray from entering the enclosure.

 

Regards

Assume

35m cable length

10amps / phase

Cable 10mm² = 0.00343Volts drop per amp per meter from cable manufactures tables) copper

 

0.00343 x 35m x10 amps = 1.20v drop (at the end of the 35m)

Have any of you ever heard of a software called Volts? It's made by a company called Dolphin. They're located out in California. It's very handy. It actuallly sizes the electrical system taking every adjustment factor into account. It also creates a one-line diagram.

The accuracy of the meter will depend on the size of the CT that was installed. If the CT/s is/are too big in capacity as compared to the power that is  actually consumed or the power that is passing through the meter, it will never give a “close to real” measurement.
