Doble power factor test transformer

WebThe M4110 Leakage Reactance test, also referred to as the short-circuit impedance test, is a reliable indicator of transformer winding deformation. The leakage reactance within a transformer is sensitive to the geometrical changes in the leakage flux path. The leakage flux path is predominantly made up of space between the winding, space within ... Webdirectly fill the power factor test cell from the sampling facility provided on the tested power transformer. One must assure that the test cell is clean and it is a wise precaution to bleed the sampling tube to assure a representative sample. Oil tests in the shop or laboratory would be carried out at room temperature (20O C)
