Kuram transformatoram ir lielāka tinumu pretestība 25kVA vai 250kVA ? https://building.lv/forums/99/158207/158207/_subject_#msg-158207 Sat, 02 May 2026 20:29:18 +0300 Phorum 5.2.23 https://building.lv/forums/99/158207/158510/_subject_#msg-158510 https://building.lv/forums/99/158207/158510/_subject_#msg-158510 25 kVA trafa augstsprieguma tinumu pretestība ~ 425 Omi, zemsprieguma tinumu ~ 0,12 Omi; 20/0,4 kV

250 kVA trafa augstprieguma tinumu pretestība ~ 4,5 Omi, zemsprieguma tinumi ~ 0.005 Omi: 10/0,4 kV
250 kVA trafa augstprieguma tinumu pretestība ~ 15 Omi, zemsprieguma tinumi ~ 0.006 Omi: 20/0,4 kV

Jo lielāka jauda, jo mazāka pretestība, 1000 kVA Augstspriegumam ~ 0,9 Omi, zemspriegumam ~ 0.0013 Omi.

P.S dots vienam tinumam, pārējiem diviem tinumiem pretestības vienādas, mērīts pie 20 grādiem]]> Pavels.O Inženiertīkli Mon, 26 Aug 2013 15:48:28 +0300 https://building.lv/forums/99/158207/158506/_subject_#msg-158506 https://building.lv/forums/99/158207/158506/_subject_#msg-158506 moldriks Inženiertīkli Mon, 26 Aug 2013 13:10:03 +0300 https://building.lv/forums/99/158207/158495/_subject_#msg-158495 https://building.lv/forums/99/158207/158495/_subject_#msg-158495 Vienstāvs Inženiertīkli Mon, 26 Aug 2013 10:57:47 +0300 https://building.lv/forums/99/158207/158474/_subject_#msg-158474 https://building.lv/forums/99/158207/158474/_subject_#msg-158474 moldriks Inženiertīkli Sat, 24 Aug 2013 21:35:29 +0300 https://building.lv/forums/99/158207/158209/_subject_#msg-158209 https://building.lv/forums/99/158207/158209/_subject_#msg-158209 Rx Inženiertīkli Tue, 13 Aug 2013 19:47:59 +0300 https://building.lv/forums/99/158207/158207/_subject_#msg-158207 https://building.lv/forums/99/158207/158207/_subject_#msg-158207 index Inženiertīkli Tue, 13 Aug 2013 17:49:58 +0300
