Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints

Techimp HQ S.r.L
Techimp Voltage Tap Adapter is gender changer which allows the user to connect to the test tap (sometimes called power factor tap) of high voltage transformer bushings.While keeping the test tap well below the safety voltage level required by the manufacturer, the Tap Adapter lets the user to drain high frequency PD signals for diagnostic assessment of insulating materials.A synchronization signal can be derived as well.It is suitable for both single shot as well as continuous PD monitoring.Although it must be customized on the basis of the shape and dimension of the test tap (to be provided by the Customer), many models are readily available for the most established transformer bushings. A list of the presently available models is reported below.Several thousands of hours of operation are a guarantee of reliability and accurate design.
