3 Phase Automatic Transformer Turns Ratio Meter-VTRM-3A/3B

VEER make Automatic Transformer Turns Ratio Meter-VTRM measures no-load Turns Ratio of Transformer. It means Ratio of High Voltage Winding to Low Voltage Winding of Transformer. It is capable to test Y-y. D-y. D-d & Y-d configuration. Turns Ratio can be read directly from front LCD display. It also measures and display % Deviation & Excitation Current. VTRM has inbuilt Data Storage Memory up to 200 Test Results. It can transfer all test results to Computer using dedicated Software & computer interface.
