Product Overview: Phenix PATTR-3D Automatic Ratio Tester
Phenix PATTR-3D Automatic Ratio Tester
Phenix PATTR-3D Automatic Ratio Tester Features:
• Rugged design is perfectly suited to tackle the most challenging field or manufacturing environments.
• Anti-induction mode strongly enhances the efficiency of the measurements by countering the unwanted effect of nearby induction interference.
• Large, high contrast, color, touch screen display offers easy menu navigation, creation of test plans and viewing of test files.
• Integrated LTC control terminal allows for manual or fully automatic testing sequence of On-Load Tap changers with configurable pulse duration and duty cycle.
• Additional tertiary winding channel saves time, with one-time test connections to primary, secondary and tertiary windings.
• Colored, graphical display of LTC test results becomes available for interpretation in seconds.
Description
With its real 3-phase test circuit, the PATTR-3D can address complex ratio measurements of Phase- Shifting/ Regulating or irregular vector group type transformers, otherwise impossible to achieve with conventional ratio meters. Zigzag type transformer testing is very easy and will not require the installation of jumpers or the use of relay matrix circuits. The single or real 3 phase voltage output up to 275 V contributes to higher magnetization currents and therefore stronger flux for better signal reflection on secondary and/or tertiary windings allowing more accurate results. The PATTR-3D phase displacement measurements enables for simple detection of the transformer vector group.
