EPTTR-E Automatic Transformer Turns Ratio Tester is used to measure the turns ratio, excitation current and polarity of windings in single- and three-phase distribution and power transformers (tested phase by phase), potential and current transformers, and tapped transformers. And can meet thetests of transformer production, installation, operation, and power preventivetest procedures.

EPWT 10A Transformer Ohmmeter, also called Transformer DC Winding Resistance Tester is applied todetect the welding quality of winding contactors are in good condition or not,and if there is turn-to-turn short circuit in winding. It also can detect theconnecting and its’ indicators of voltage on load tap changer are in goodcondition or not.

EPWT is designedspecifically to measure DC resistance values of transformer windings and any DCresistance of an inductive device.
