The most accurate method for determining the turn ratio of a transformer is the impedance method, which involves measuring the primary and secondary impedances under load conditions. This approach accounts for the effects of winding resistances and leakage reactances, providing a more realistic representation of the transformer's performance. Unlike the open-circuit or short-circuit methods, the impedance method reflects actual operating conditions, leading to a more precise turn ratio assessment.

Why auto transformer is lighter than conventional type?
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
How do you determine transformer turns ratio if the supply source and load is given?
Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
How do you calculate voltage ratio of three phase transformer?
To calculate the voltage ratio of a three-phase transformer, you divide the primary voltage (Vp) by the secondary voltage (Vs). The formula is expressed as Voltage Ratio (Vr) = Vp / Vs. This ratio indicates how the transformer steps up or steps down the voltage between the primary and secondary windings. Additionally, ensure the voltages are measured in the same phase configuration (e.g., line-to-line or line-to-neutral) for accurate results.
