A Transformer Turns Ratio Test Set such as the TTR25 can directly measure the turns ratio of single-phase transformers as well as three-phase transformers. Deviations in these measurements will quickly indicate problems in transformer windings and in the magnetic core circuits. Transformer ratio can change due to several factors, including physical damage from faults, deteriorated insulation, contamination and shipping damage. If a transformer ratio deviates more than 0.5 percent from the rated voltage ratio, it may not operate reliably. To measure small ratio changes such as this, the accuracy of a Megger TTR25 is needed.

Transformer turns ratio is the ratio of the number of turns in the high-voltage winding to that in the lowvoltage winding. Complexity in the measured ratio versus nameplate ratio occurs with most three-phase power transformers because multipliers such as √3 are required to match the measured ratio to the nameplate ratio. The TTR300 Series automatically applies the multiplier in a form which allows the operator a direct comparison to the nameplate (or expected) ratio. The built-in calculator displays the % error versus nameplate for each tap and each winding, without the need for a computer.

A transformer turns ratio test set such as the TTR20-1 can directly measure the turns ratio of single-phase transformers as well as three-phase transformers. Deviations in these measurements will quickly indicate problems in transformer windings and in the magnetic core circuits. Transformer ratio can change due to several factors, including physical damage from faults, deteriorated insulation, contamination and shipping damage. If a transformer ratio deviates more than 0.5 percent from the rated nameplate ratio, it may have a fault, which reflects in inefficient or improper operation. To measure small ratio changes such as this, the accuracy of a Megger TTR20-1 is needed.
