- etap.com - In this webinar, learn how to obtain accurate and economical ground grid designs by quickly identifying appropriate ground grid layouts, while efficiently conducting studies using integrated fault analysis tools.
ETAP's Ground Grid Systems software enables engineers to quickly and accurately design and analyze ground protection. Advanced 3-D technology integrates with one-line diagrams, enabling engineers to visualize their ground systems in 3-D plots and seamlessly utilize short circuit results. Flexible design methodologies allow for quick auto-designed layouts or detailed schemes.

For the SEV (Vertical Electrical Sounding) method, in which resistivity measurements are taken at different depths, how do I define the two layers for the calculation? I am currently working on ETAP 12.6.0
Great! Thank you so much !
Thank you for your interest in ETAP Solutions and your positive feedback.
Thank you so much for your sharing, but i have a question that in some case, we design system with special shapes such as the grounding system of the wind turbine (Circle shape) or in case of low resistance need to install additional wells, in which case how to handle it. Looking forward to the answer.

Hi! I'd like to ask you how to associate the Rg value in order to modify line-ground faults, i mean Isc = Vf/(Z1+Z2+Z0+Rg). Thanks.

Thank you so much for your sharing!
However, I have some question for some part of the software function. For Soil Editor, Soil Analysis function, mostly you put data from filed test (4 points test/wenner);then, you got result from it. What is the difference between soil resistivity result at site and software? Other points, the result also show the depth of surface layer, how did software solve soil structure without soil investigation (Dig/SPT/etc method)?
Thank you for your answer in advance!

Hello, the program requires the 2 layers soil model. Therefore it is necessary to convert the field test data into the the required model. The soil analysis helps the conversion. This conversion is similar to the Sunde graphic method as described by IEEE80. It is suggested to contact ETAP support for further questions as this topic is a little bit involved.
@@yichenbi3863 Thank you for your explanation! However, what is the difference between field data measurement and field data calculated by the software?
Hi, do not you have hard-drawn copper material for the earth grid? Some client is specific for hard drawn copper.

Hi, for older substation, how should I measure if the ground mat/ grid is still within the acceptable standards?
Thank you for your interest in ETAP Software. Your question was forwarded to one of our engineers who will be in touch shortly. In the mean time feel free to contact our 24/7 online Help Center at support@etap.com
Hello Christopher, generally you can still model the old substation based on its original drawings or you can measure its ground impedance.
@@yichenbi3863 Hi, Also is very important measure Step and Touch voltage in Old substation and cheack if the value comply with the IEEE 80 what is the most important than Ground impedance. Saludos
how to design the earthmat using bentonite treatment for limiting the Rg value to desired value?

Hi, How can change unit system to metric system in ground grid analysis?
i cant find
Thank you for your interest in ETAP solutions. You would have to start your project in IEC standard mode and it will automatically use metric units. Please feel free to contact our 24/7 Help Center if you need further assistance: helpcenter.etap.com
nice
Thank you for your interest in ETAP Solutions and your positive feedback.
Could you share the material ? Thanks
Thank you for your interest in ETAP solutions. We typically do not share our presenter files. Please feel free to contact our 24/7 Help Center if you need further assistance: helpcenter.etap.com
I'm really not trying to be a jerk here but in the interest of giving you some feedback that will improve future presentations, consider using the phrase Ummm a little less. You do it excessively and it makes it difficult to follow your information stream. Otherwise it was a great and thorough presentation!
