    O que é o testador DC hipot?

    WHAT IS DC HIPOT TESTER ? For medium to high voltage rotating equipment, DC Hipot tests called Step Voltage or Ramp tests are used to see if the start of an insulation breakdown can be detected as the voltage is raised. If a breakdown is starting the test can be terminated before there is an […]

    Transformer 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 […]
