You’ve run the test. The screen flashes a ratio deviation of 2.3%—far beyond the acceptable ±0.5%. Your mind races: Is this a shorted turn? A

For twenty-five years, I’ve reviewed thousands of transformer excitation current test sheets. Without fail, a new engineer or technician will point to the results and

For over twenty years, I’ve stood in substations and plant floors, the hum of transformers in the background, a turns ratio tester in my hand.

The Transformer Turn Ratio (TTR) test is a critical diagnostic procedure used to verify the voltage ratio, phase angle, and polarity of transformer windings. Using

A Transformer Turn Ratio (TTR) tester is an essential diagnostic instrument used to ensure that a transformer’s voltage windings are correct according to its design

In my decades as a power systems specialist, I’ve come to view the Transformer Turns Ratio (TTR) Tester as more than just a piece of equipment. It’s

Over my career, I’ve seen more TTR testers than I can count—from old hand-cranked units to the latest digital powerhouses. I’ve also seen companies make

In my years of diagnosing high-voltage transformers, I’ve seen it all. The TTR (Transformer Turns Ratio) test is one of our most fundamental and powerful

Xin chào, my respected colleagues in Vietnam’s power and industrial sectors. Over my many years in this field, I’ve had the privilege of working alongside
