Hi David.
Here in Europe we usually put a reactance (zig-zag configuration) for creating an artificial neutral point in a MV system where the connection of the winding transformer of this side is in delta. So with the help of the reactance we get a route to earth in the case that an earth...
Good morning.
Thankyou very much tem1234, dpc and specialy for alehman for your help.
Maybe what I am looking for are the design criteria.
I know that the zig-zag grounding transformer is for the limitation of earth fault.
If in the 34.5kV collecting system the fault criteria is a...
No . I haven't tried it !. I have a companion that will contact them, but due to my responsability in my Company I have to find answers on my own way.
And I have to report to the Management separately from others.
I don't know if you mean on the side that I am...
Thanks for your...
I am asking for criteria design and applicable standards that the Electrical Company can give as criteria design and withouth cost.
The electrical Companies usually have a list of approved vendor for each equipment and this is also free of charge.
I am not requiring conceptual design...
Hello.
Please, can anybody indicate wich are the specification(s) for a 34,5kV zig-zag grounding transformer for a Windfarm in Kansas ( KCP& L Electrical company )?
I guess that this equipment has to comply with IEEE 32 Std. , however I need to know the KCP&L requirements and/or...
Hello.
This is a question for Transformers manufacturer. It is possible to design a power transfomer elevator for a voltage of 11 / 400 kV and a power of 60 MVA or having 11kV at primary and for this power the secondary has the limit of 220 kV?.
Any data from IEC Std. related to typical...
Dear Colleagues.
I am working in Spain for a spanish Company who promotes, builds and operates Wind Farms and Thermosolar Power Plants.
In accordance with a possible project in USA of a Wind Farm I have to do some calculations related to drop voltage, power losses in buried cables so I...
