The instrument’s rugged design is perfectly suited to tackle the most challenging field or manufacturing environments. The anti-induction mode strongly enhances the efficiency of the measurements by countering the unwanted effect of nearby induc- tion interference. The large, high contrast, color, touch screen display offers easy menu navigation, creation of test plans and viewing of test files. The integrated LTC control terminal allows for manual or fully automatic testing sequence of On-Load Tap changers with configurable pulse duration and duty cycle.


With ART-3D’s™ intuitive menus, high contrast touch screen, convenient graphical test representa- tion, highest test voltage on the market, long and flexible multipurpose test leads configuration, real 3-phase output, the widest range of applicable transformer types, it has never been so simple and easy to achieve high accuracy Transformer Turn Ratio measurements.
