Stabilizing (Buried Delta Tertiary) Winding | Winding Resistance Test

Stabilizing (Buried Delta Tertiary) Winding | Winding Resistance Test
Stabilizing winding aka buried delta tertiary windings are used to carry zero sequence and triplen harmonics as well as stabilizing the neutral. If two terminals of one delta corner are brought out to two bushings, total winding resistance (sum of all winding resistances) test can be performed. There is no way to measure each winding’s resistance test since the other corners are not brought out. The measured total resistance value can then be compared to the test report value.
