Product Description

Transformer turn ratio tester(TTR)

The turns ratio or voltage ratio test of the running transformer can check the correctness of the turns ratio of the transformer, the condition of the tap changer, whether the transformer is short-circuited between turns, and whether the transformer can operate in parallel. The operation is simple and intuitive. It adopts a three-phase precision inverter power supply, and the test is fast and accurate. It can test both single-phase and three-phase simultaneously.
 
For the three-phase transformation ratio test, the transformation ratio value, error, and tap position are automatically calculated. For the three-phase group test, the transformation ratio value, error, tap position, and group number are automatically calculated. In addition, it can also measure the angle between phases.
