XTRM-3

The XTRM-3 measures the transformer turns ratio of single phase and three phase transformers using modern electronic techniques. This replaces the Ratio testers using ‘current balancing bridge’ circuits, requiring manual ‘null’ balancing. XTRM-3 incorporates breakthrough technology and design that gives accurate and reliable results repeatedly. It is micro controller operated, user friendly and reliable. XTRM-3 incorporates a large LCD screen for display of menu and results. The entire test is automated and quick. Operator enters the test parameters and XTRM-3 takes over, applies the test voltage, balances the bridge, takes the readings, and displays the results on the LCD screen. The results can be printed on built-in printer after the test is over. A Windows based software is provided for easy operations via USB communication port. LV and HV windings are automatically isolated after the measurement is over. The XTRM-3 is a single unit, lightweight portable design, encased in a hard industrial cabinet weighing only 10 kgs.

XTRM-3A incorporates breakthrough technology and design that gives accurate and reliable results repeatedly. It is micro controller operated user friendly and reliable tester. XTRM-3A incorporates a large LCD screen for display of menu and results. The entire test is done automatically and quickly. Operator enters the test parameters and XTRM-3A takes over, applies the test voltage, balances the bridge, takes the readings, and displays the results on the LCD screen. The results can be printed on built-in printer after the test is over. The windows based software is provided for easy operations of the Turn Ratio Meter via USB communication port. The automatic detection of transformer vector group, Measurement of Turns ratio, Voltage ratio, Ratio error, Phase angle & Excitation current are the key features of the XTRM-3A. LV and HV windings are automatically isolated after the measurement is over. The XTRM-3A is a single unit design, encased in an hard industrial cabinet, lightweight (only 15 kg), achieving portability.
