Hi
I asked to move 3 phase transformer to new pole.
This 3 phase transformer is feeding apartment building from pole to underground service.
Currently this tx 3-50kva ,600/347 V, 4-4/0 Al.
they gave me the peak load on tx is 135 kva.
77 residents in apartment all 120/240. But i don't know the...
I think you are right Mbrooke. He might done it opposite way.
He has from
TX-------------------Point A Cable-----------------------point B cable.
5.26% --------- 1.26%dropA + 5.26------------- 2% drop on cableB + 5.26
Voltage drop--------=6.52% Total drop on point A---------=7.26%
Yes Waroos, this calculation is for voltage drop on initial stage .
There are loads attached to Transformer , But I don't know Which Kva he used! 100kva or 230KVa.
I am getting only 3.6% on transformer . I believe I am using either wrong voltage or Kva..
My supervisor is not here at the moment , and he is using special calculator.
So base on this information :
Primary voltage 16000V ,Secondary voltage 120/240
TX= 100 KVA %z=3.3 x/R=3.1
Do you guys get 3.28% voltage drop as well?
This is only voltage drop on Transformer...
Thank you
But He has done it with calculator , see picture.
I don't know how he got 5.26%http://files.engineering.com/getfile.aspx?folder=96633b3b-8aaf-46d0-8404-54b7488b8df6&file=ali.png
I am trying to calculate voltage drop on my transformer...
Primary voltage 16000V ,Secondary voltage 120/240
TX= 100 KVA %z=3.3 1phase
Can anyone help me how to calculate voltage drop on transformer.
The result of my calculation is given me 3.28% voltage drop, However my Supervisor...
