Hi, all.
We are testing a new three winding transformer (4,5 MVA 13.8 kV Delta / 2,25 MVA 0,48 kV Wye / 2,25 MVA 0,48 kV Wye) to obtain the percentual impedance of windings. We obtained the following results:
-Voltage applied in 13.89 kV winding with secondary short-circuited and tertiary...
Hello everybody.
I was looking for AVR models to install in a 25MW 13.8 kV generator, for an industrial usage.
We are substituting the old AVR's units by new ones. What are good manufacturers for this products?
Best Regards!

Can anyone know where I find the demo version of Siemens DIGSI 4.0? I was trying to install 4.83 demo version, but it was required de old version first. Thanks.
Hello.
In our industrial plant, we have some problems during an induction motor starting. I'd like to talk about ideas to solve this problem. The electrical diagram is attached.
Describing the problem:
Two generators (A and B) connected in two load bars (A and B) that connect to a...
Hello. I need some help.
In my area we have a 13.8kV, 74.3 MVA generator (wye connection) connected to a 80 MVA 13.8/69 kV (delta/ground-wye) transformer. The 69 kV side of this transformer is connected to a bus fed by a 100MVA 230/69 kV (grounded wye/grounded wye). The 230 kV side of this...
