Three Phase Transformer Turns Ratio Test Set

Product Description

GDBC-901 Three Phase Transformer Turns Ratio Test Set



When the substation is put into use, the transformer is an important device to ensure the voltage stability of the electricity used by the substation and the output power.

Through the test, it can be verified whether the voltage conversion of the transformer is correct, and it is also possible to check whether the turns ratio of each coil is consistent with the design, whether the tap leads are connected correctly, and whether the transformer turns are short-circuited, etc. Whether the transformer can be put into operation depends on judge the test results.
