TTR Tester

TTR Tester
Product Code : VTRM
Product Description


Veer Make Autometic Transformer turns ratio meter - VTRM measures no-load turns ratio of transformer. It means ratio of high voltage winding to low voltage winding transformer. It is capable to test Y-Y, D-Y,D-D & Y-D can read turns ratio directly from front LCD display. It also measures and display % deviation & excitation current. VTRM has inbuilt data storage memory up to 200 test result.It can transfer all test result to computer using dedicated software & computer interface

Key Features:


  • Automatic measurement of Transformer Turn Ratio
  • Excitation Current, HV & LV Voltage, Polarity & %Deviation
  • 36 Vector Group Selection Facility (In Selected Model)
  • 3-Phase Connections enables simplel and faster testing
  • Test voltage through ON/OFF switch & LED Indication
  • Turns Ratio 1:200 / 1:2000
  • Basic Accurancy +0.1% Accurate measurement
  • 20 x 4 LCD to Display all Parameters in Single Screen
  • Hold Facility To Freeze Result with LED indication
  • Reverse Polarity Indication by LED & LCD
  • Over Current Protection for shorten Winding
  • 200 Test Data Storage Inbuilt (500 Optional)
  • RS 232 & USB Optional Interface with Software (Optional)
  • Portable in Size ( Table Top & Panel Mount )
