Typical current for 2 x 25 MVA transformers is 150 A, 150 kV and of course secondary at 15 kV, 1500 A. The regulation is done automatically with tap changers, live. The local transformers at your neighborhood are fixed tap, 15 kV (they intend to change everything to 20 kV). So they have developed 100% efficient transformers? -- http://improve-usenet.org/index.html Use any search engine other than Google till they stop polluting USENET with porn and junk commercial SPAM If you have broadband, your ISP may have a NNTP news server included in your account: http://www.usenettools.net/ISP.htm |
