transformer turns ratio meter fully automatic-trm-11 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. lv and hv windings are automatically isolated once the measurement is over. true portability is achieved by the lightweight (only 10 kg), single unit design housing the trm-11. the trm-11 is encased in an aluminum alloy cabinet.
