testing power ▪ Multi function system for transformer/substation transformers, CTs, VTs, and many other substation testing components. A variety of voltage and current levels ▪ Outstanding flexibility for selecting output current can be generated and measured with high precision or voltage signals for various tests which allows the test system to be used for a wide range of applications such as ratio, excitation, resist- ▪ State of art measurement methods for advanced ance, impedance and primary measurements of power diagnostic testing system components. ▪ Compact and lightweight User interface TRAX user interface architecture is based on a number of individual apps/instruments dedicated for a specific measurements or application. For manual testing, a generic instrument, Manual Control, is available where the user selects output, measurement inputs and how the data should be processed. For testing complete power products e.g. power transformers, measurement results from different instruments can be stored and reported for the specific object. Applications A variety of voltage and current levels can be generated and measured with high precision which allows the test system to be used for a wide range of applications. Examples are:
