Transformer Turns Ratio Tester

Ratio testers using manual `current measuring bridge circuits are now outdated. Udey model TRM-11 is a new, fully automatic tester that measures transformation ratio of single phase and three phase transformers using modern electronic techniques. TRM-11 is micro controller operated user friendly, accurate, reliable, small, light weight and reliable tester. TRM-11 incorporates a large LCD screen for display of menu and results. The results can be stored and printed on built-in printer after the test is over. TRM-11 incorporates breakthrough technology and design that gives accurate and reliable results, again and again. This is a new generation, fully automatic, transformer turns ratio tester designed for measuring ratio, ratio error of single and three phase transformers. The entire test is done automatically and quickly. Operator enters the test parameters and TRM-11 takes over; powers up the voltage, balances the bridge, takes the readings, and displays the results on the LCD screen. Prints test results through its built-in printer. A key feature of the TRM-11 is automatic measure transformer connection group. Automatic cut over takes place if wrong phase sequence is incorrect during connections. LV and HV windings are automatically isolated once the measurement is over. True portability is achieved by the lightweight [only 10kg], single unit design housing the unit. The TRM-11 is encased in an aluminium alloy cabinet.
