TTRM 101
SCOPE introduces state of the art precision single phase Transformer Turns Ratio Meter (TTRM ) designed for field testing as well as factory testing of power transformers, instrument transformers and distribution transformers of all types. TTRM 101 measures only turns ratio where as TTRM 102 along with turns ratio, measures ratio deviation, phase angle deviation, magnetizing current and detects tap-position of single phase transformer in charged switchyard condition. The range of AC voltage selection offers high accuracy in measurement.Both the instrument have in-built TFT display with touch screen and thermal printer. The user friendly, simple instrument makes the testing more easy. With the touch keypad it is possible to enter required DUT information.The ratio results are displayed with % error. Internal non-volatile memory gives the provision of storing test results.Further data can be downloaded to PC or copied to memory stick through USB port provided.
The C-Trans-software, gives the flexibility to download the stored results to PC and do the further analysis and report generation.
