About Turns Ratio Meter - TTRM 302

The state-of-the-art precision three-phase Transformer Turns Ratio Meter (TTRM ) is designed for field testing as well as factory testing of power transformers, instrument transformers and distribution transformers of all types. Along with turns ratio, this lightweight and reliable instrument measures ratio deviation, phase angle deviation, and magnetizing current and also detects tap-position of single as well as three-phase transformers in charged switchyard conditions. The instrument has the facility to automatically detect vector groups of all majority configurations available. The different AC voltage selection offers high accuracy in measurement.

The instrument has an in-built TFT display with a touch screen and thermal printer. The user-friendly, simple instrument makes testing easier. The touch keypad helps to enter the required DUT information. The ratio results of all the phases are displayed in tabular form with % error. Internal non-volatile memory gives the provision of storing test results. Further data can be downloaded to a PC or copied to a memory stick through the USB port provided. The CTrans-TTRM software gives the flexibility to download the stored results to PC and do further analysis and report generation.
