My issue is that I could not have found any specific info about import-export capability of EMTP, indeed EMTP compatibility with other electromagnetic transient simulation programs. (I (consultancy firm) intend to exchange simulation “platform” to EMTP. I wrote here intentionally instead of requiring pricing, specs officially.)
It exists some solutions for very specific needs, please contact info@emtp.com if you want to have a chat.
However there isn’t any fully supported import/export tools yet. We are pushing the industry to use the CIM format, which is a universel format for any software, and we can already import this format, but not every software vendors show the same enthusiasm about it.
