trefases

Could you clarify what trefases refers to? The term isn’t widely established in English and could mean different things in different contexts. It might be a linguistic form meaning “three phases” in some languages and could relate to three-phase electrical systems, or it could be the name of a project, organization, or fictional concept. If you can specify the intended meaning or provide a source, I can write a concise, neutral wiki-style article.

If you’d like, I can also provide a general, neutral article about three-phase electrical systems (often termed in various languages as “trefases” or similar), covering basic concepts such as phase voltages, star and delta configurations, and common applications, in plain, concise prose.
