Among them are parameters representing possible technical failures, such as network&amp;rsquo;s short circuit current and voltage sag. Specialists find these parameters and detect technical failures. However, this process can become time-consuming. Thus, this article proposes an ontology called OntoFreya, which classifies voltage, current, or any electric metric, following the definitions of the regulatory agencies and reducing the time spent on this task. A series of 4402 axioms, 132 classes, and 40 data properties comprises OntoFreya. The ontology automatically inferred classifications for four hundred readings from energy samples, validating OntoFreya across three scenarios. The first and second scenarios classified current in amperes, and the third classified voltage in per-unit system (pu). The scenarios showed that OntoFreya automates the classification of electric metrics, reducing specialists&amp;rsquo; time in detecting technical failures in a distribution network.<\/jats:p>","DOI":"10.3897\/jucs.145075","type":"journal-article","created":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T14:31:44Z","timestamp":1774276304000},"page":"337-356","source":"Crossref","is-referenced-by-count":0,"title":["OntoFreya: A Power Distribution Ontology for Electric Metrics Classification"],"prefix":"10.3897","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9775-5842","authenticated-orcid":true,"given":"Jorge Arthur","family":"Schneider Aranda","sequence":"first","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"},{"name":"Federal Institute of Education, Science and Technology, Veran\u00f3polis, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7929-1984","authenticated-orcid":true,"given":"Ricardo","family":"dos Santos Costa","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9178-2380","authenticated-orcid":true,"given":"Vitor","family":"Werner de Vargas","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9599-2476","authenticated-orcid":true,"given":"Paulo Ricardo","family":"da Silva Pereira","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0358-2056","authenticated-orcid":true,"given":"Jorge Luis","family":"Vict\u00f3ria Barbosa","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}]},{"given":"Marcelo","family":"Pinto Vianna","sequence":"additional","affiliation":[{"name":"CEEE-D Power Utility, Porto Alegre, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5531-3907","authenticated-orcid":true,"given":"Eleandro Luis Marques","family":"da Silva","sequence":"additional","affiliation":[{"name":"Certaja Energy, Taquari, Brazil"}]}],"member":"2258","published-online":{"date-parts":[[2026,3,28]]},"container-title":["JUCS - Journal of Universal Computer Science"],"original-title":[],"link":[{"URL":"https:\/\/lib.jucs.org\/article\/145075\/download\/pdf\/","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/lib.jucs.org\/article\/145075\/download\/xml\/","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/lib.jucs.org\/article\/145075\/download\/pdf\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T14:31:45Z","timestamp":1774276305000},"score":1,"resource":{"primary":{"URL":"https:\/\/lib.jucs.org\/article\/145075\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,28]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,3,28]]}},"URL":"https:\/\/doi.org\/10.3897\/jucs.145075","relation":{},"ISSN":["0948-6968","0948-695X"],"issn-type":[{"value":"0948-6968","type":"electronic"},{"value":"0948-695X","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,28]]}}}
