Thanks for your comments.
I'm using ETAP ground grid package for my simulation which is not as powerful as CDEGS for Grounding applications. It can only handle 2-3 horizontal soil layers.
I do have soil resistivity results. The problem is that the site is located in Northern Canada. Typically...
Thanks cuky2000,
The problem is the path to earth. As I mentioned the whole plant is on a bedrock (which acts more like an insulator), so even if I use ground plates or ground electrodes in significant numbers, I won't have much contributions to my grounding.
Hi,
I'm designing grounding system of a 25KV substation. However, I have been told that the whole plant is located on a bedrock(at least minimum 13m deep). Driving 20ft ground rods will not contribute much to my grounding design.
What other options do I have in order to improve my grounding...
I am an electrical engineer in training working in the area of power system.
I have been given a transformer test report from a manufacturer.
The transformer has the following information:
Rating: 24/32/40 MVA.
Voltage: 138 KV HV (wye) – 34.5 KV LV (wye) – 7.2 KV Tertiary (Delta)
Impedance at...
I am an electrical engineer in training working for an engineering firm.
Currently I am working on some technical aspects of a substation of a Wind Farm Project.
The main transformer for this substation has a rating of 34.5/138 KV (wye/wye configuration) Rating with buried Delta in Tertiary.
I...
