This paper addresses these problems and associated relay operations. The following incidents are reviewed: 1) Failure of 6.9kV transformer drive cable and operation of protective relaying; 2) Detection of problem on First Energy's 138kV utility power system with new microprocessor based relays; 3) Failure of 138kV transformer primary cable and operation of protective relaying. All three incidents were associated with transformer K10, one of four transformers feeding the 10 x 10 SWT complex.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Nasa Technical Reports Server (Ntrs),Cass Kuhl\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1287292569\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781287292562\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/07\/2013\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 22\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.13lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.05d","brand":"Nasa Technical Reports Server (Ntrs)","offers":[{"title":"Paperback","offer_id":47611328332031,"sku":"9781287292562","price":14.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_4cd5201a-dcbb-4e5b-86b8-e7b32d6d0375.jpg?v=1764513187","url":"https:\/\/www.whiterainbookhouse.com\/products\/cable-failures-and-protective-relay-nasa-technical-reports-server-ntrs-9781287292562","provider":"WR Book House","version":"1.0","type":"link"}
