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 […]
