1) 1.under voltage realy (uv) Uv voltage value-Voltage%-tripping milli second 0.9 times, 1 to 3 sec 2.over voltage realy (ov) OV voltage value-Voltage%-tripping milli second 1.1times, 1to2sec 3.over current realy (oc) Oc current value-current%-tripping milli second 1.IDMT realy ( inverse definite minimum time) Oc current value-current%-tripping milli second 1.1times, 150msec 2. Instantaneous realy Oc current value-current%-tripping milli second 1.5 to 3 times, 100mSec 3. definite Time realy Oc current value-current%-tripping milli second 1.5 times, 200mSec 4.Earth fault realy ( E/F) Fault current value-current%-tripping milli second 1.Ref realy ( Restricted earth fault) Fault current value-current%-tripping milli second 0.1times, 50 to 100mSec 2.Sef realy ( sensitive earth fault) Fault current value-current%-tripping milli second 0.1 to 0.15times, 50 to 100 mSec 5. Differential realy Different current value-current%-tripping milli second 0.05times, 50mSec 6.buchholz realy (Buc) Minimum pressure valve alarm- Maximum pressure valve trip see my video for transformer protection 7.pressor realise value (Prv) Minimum pressure valve alarm- Maximum pressure valve trip see my video for transformer protection 8.Winding temperature (Wti? Minimum temp alarm- maximum temp trip 80 alarm, 95 trip 9.oil temperature (Oti) Minimum temp alarm- maximum temp trip 90 alarm, 110 trip 10. Magnetic oil Gage (Mog) mog for only alram circuit this all are approximate value defend up on the application may be changed
