How to Perform a Transformer Turns Ratio Test
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 the specific “Transformer turn ratio tester” detailed in the manual, the process involves strict safety protocols, digital parameter setup, and precise wiring. 1. Safety Prerequisites Before touching the instrument or […]
How Does a Transformer Turn Ratio Tester Work?
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 specifications. By measuring the ratio between the high-voltage (HV) and low-voltage (LV) windings, technicians can verify the transformer’s performance, polarity, and vector group. Based on the technical documentation, here is […]
From Factory to Field: The TTR Tester’s Critical Role at Every Stage of a Transformer’s Life
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 a transformer’s lifelong companion, a biographer that tells its story from the moment of its creation to its final days in service. The TTR test is the single most versatile […]
My Expert Procurement Guide: The 6-Point Checklist for Your Next TTR Tester
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 costly mistakes by purchasing the wrong instrument for their needs.

My Expert Take: In Contact Resistance Testing, It’s All About the Micro-ohms
After decades spent on substation floors and in industrial plants, I can tell you that the most devastating electrical failures are often caused by the problems you can’t see. I’m talking about the silent killer of electrical connections: resistance. A few extra micro-ohms (µΩ) on a circuit breaker contact or a busbar joint might seem […]
My Expert View: In Winding Resistance Testing, Accuracy Isn’t a Feature—It’s the Entire Point
In my decades of diagnosing high-voltage transformers, I’ve learned a hard lesson: the most catastrophic failures often start with the smallest, most insignificant-seeming deviations. When it comes to Transformer Winding DC Resistance Testing, there is no room for “close enough.” The single most critical factor I demand from my equipment is uncompromising measurement accuracy and precision. This […]
My Expert Take: Why Measurement Range and Accuracy are Non-Negotiable in a TTR Tester – And How HVTestTech Delivers
After years in the field, analyzing the health of countless transformers, I can tell you that the two questions I get most often from clients choosing a Transformer Turns Ratio (TTR) Tester are always the same: “Can it measure all my transformers?” and “Is it accurate enough to find real problems?” These aren’t just technical questions; they […]
