Product Description

Introduction: Ratio testers using manual ‘current measuring bridge' circuits are now out date d.
DY-100 is a new, fully automatic tester that measures tr ansformation ratio of single phase and
three phase transformers using modern electronic techniques. DY-100 is micro controller oper ated user
friendly, accurate, reliable, small, light weight and reliable tester. DY-100 incorpor ates a large LCD
screen for display of menu and results. The results can be stored & printed on built-in printer after the
test is over. DY-100 incorpor ates breakthrough technology and design that gives accurate and reliable
results, again and again.

Description:DY-100 is a new generation, fully automatic, tr ansformer turns r atio 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 DY-100 tak es 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 DY-100 is automatic measure tr ansformer
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 DY-100. The
DY-100 is encased in an aluminum allo y cabinet.
