Ratio testers using ‘current balancing bridge’ circuits are now out dated. model HYG-II is a new, fully automatic tester that measures transformation ratio of single phase and three phase transformers using modern electronic techniques and does not require any manual ‘null’ balancing. HYG-II is micro controller operated user friendly, accurate, small, light weight and reliable tester. HYG-II incorporates a large LCD screen for display of menu and results. The results can be printed on built-in printer after the test is over. HYG-II incorporates breakthrough technology and design that gives accurate and reliable results, again and again.

The advantages of HYG-II

· Fully automatic: no manual balancing required

· Test single phase and three phase transformers

· Automatic measure transformer connection group

· Automatic process transformation of group

· Automatic calculation of ratio error

· Isolates test voltage automatically after test

· Test results saved automatically

· Recall and print last 30 test results

· Prints results on built-in printer


· Micro-controller operated

· Front panel with legend

· Built-in printer

· Can re call stored last 30 tests results.

· Weight: 10 kg

Safety Features

· Automatic cutoff after test

· When data exceeds 30, the last is saved as 30th

And the 1st one is deleted.

· Fuse protection for line short circuit

· Fuse protection and reset protection for reverse connection of HV and LV winding


HYG-II 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 HYG-II 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 HYG-II 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 HYG-II. The HYG-II is encased in an aluminum alloy cabinet.
