Show You Two Type Transformer Turns Ratio tester, which one do u like?
Ler maisTransformer Turns Ratio (TTR) testing is one of the most common ways of assessing the condition of a transformer’s windings and core. Throughout the life of a transformer, TTR results are compared against the nameplate ratings to reveal insulation deterioration, shorted turns, core heating or other abnormalities. Here show you the transformer ratio test datasheet and […]

Karl Fischer Coulometric Titrator
Ler maisKarl Fischer titration is a titration method that uses volumetric or coulometric titration to determine the quantity of water present in a given analyte. Why Karl Fischer is used? Karl Fischer (KF) titration is a redox reaction which uses the consumption of water during the reaction to measure the amount of water in a sample. It is the reference […]

More information about the TTR tester
Ler maisCurrent Ratio Tester Three Phase Transformer Turns Ratio TTR Tester The ratio test ensures that the transformer windings have the proper turns to produce the voltages required. The ratio is a measure of the voltage applied to the primary terminals to the voltage measured at the secondary terminals. What is the purpose of transformer turns ratio test? […]

How do you test the winding resistance of a transformer
Ler maisⅠ: How do you test the winding resistance of a transformer? Transformer winding resistance measurements are obtained by passing a known DC current through the winding under test and measuring the voltage drop across each terminal (Ohm’s Law). Winding resistance in transformers will change due to shorted turns, loose connections, or deteriorating contacts in tap changers. Regardless of […]
