Turns Ratio Meter
Product Code : VTRM
Brand Name : VEER ELECTRONICS
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 Configuration.you 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.
