Transformer Turns Ratio TTR Instrument Single/Three Phase Turn Ratio Test Meter  


Turns Ratio between the Windings

The power transformer turns ratio test is an AC low voltage test conducted to determine the ratio between the high voltage winding and all other windings when the transformer is unloaded. This test is performed on every tap of each individual winding to ensure accurate measurement.


The Transformer Turns Ratio tester (TTR) is device used to measure the turns ratio between the windings (example shown below)

Connection Scheme


Voltage is applied on the H marked leads and measured of the X marked lead by the test set.
Ratio measurements are conducted on all tap positions and calculated by dividing the induced voltage reading into the applied voltage value. When ratio tests are being made on three-phase transformers, the ratio is taken on one phase at a time with a three-phase TTR until the ratio measurements of all three phases are completed.

Connect the H0, H1, H2, and H3 test cables to the corresponding high-voltage winding terminals of the transformer under test. With delta connected windings, H0 is not used.
Connect the X0, X1, X2, and X3 test cables to the corresponding low-voltage winding of the transformer under test. With delta connected windings, X0 is not used.
It is possible to test single phase two-winding transformers with a three-phase TTR test set by only utilizing the H1, H2 and X1, X2 leads.

Common Trouble Shooting
