Hi,
I was wondering. Basic principal is DOL starter has a higher inrush current than STAR DELTA starter. Now, How about if I configure the DOL with STAR configuration. It will be same inrush current with STAR DELTA, or its still higher?
PS: What does it mean of student posting in "start a new...
Hi Skogsgurra,
Yes, I asked RST at 3 phase system.
RST and L1/L2/L3 also U V W in motor, it is just a letter or have any means?
Like alfa, beta, gamma. It came from first letter of Yunani's alphabet.
Like x, y and z. It came from last letter of alphabet.
@desrod
ya, I will ask someone that experienced in ETAP to coach me.
Thanks for your advice desrod.
@michaelusa
Ya, you are right my eff around 92.3%. I think is default for motor in ETAP.
Thanks for your kind reply.
@desrod
I am new in power electric system also new in ETAP.
You are right. I entering another %Z value in impedance of transformer and the result is different.
Do you have any recommended link to learn power system (load flow) and also learn ETAP?
I am glad if you have one for me.
Thanks for...
Hai, I'd attach file (pic of my simulation in ETAP)
I have several question:
1. Look at transformer. Input of transformer has 325+147j and output has 323+139j. Why this thing happen? Transformer lost around 2 KW.
2. Motor need 300KW, but the input supply more than 300K, is 323+139j. Why this...
