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 19520 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 19520 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)

Ltekonline are the manufacturers of Ratio Tester used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Test and Measurement Instruments for Engineering Teaching Lab in Universities
