Hi.
Can anyone tell me what the advantages are on using a Yd3 vector group. These transformers are feeding a paper mill plant.
Can anyone suggest reading material or papers explaining the reasons for the different vector groups.
I understand how the phase shift occur. It is why that I am not...
For Loadflow Analyses, I recommend using cable impedance etc, calculated at about 40 deg celc.(Higher impedance = larger voltage drope).
From my point of view, I recommend you keep the load flow and sc study seperate.
I use a system temperature of about 25 deg celc. There are a couple of...
I have a similar problem. I have to design a 11kV/415V, YNd11 - mobile substation. The LV will be connected to 1000 - 2000 kVA generators, Connected Y - grounded. When the HV breaker is closed with the LV breaker open. No earthing point exist on the LV. The LV will be proteced by a residual...
