Product Features
1.Special Transformer Turns Ratio Tester is especially suitable for testing the turns ratio and phase difference of special transformers.
2. Especially suitable for measuring rectifier transformers with phase shifting, intuitively displaying the phase shift angle.
3、Automatically generates three-phase (120°) or two-phase (90°) power with stable amplitude and constant phase.
4、Not constrained by the internal wiring of the transformer, directly measures the voltage ratio and phase angle difference between the high and low voltage sides.
5、True three-phase simultaneous measurement.
6��Test parameters are set at once; after switching the tap changer, test directly, automatically determining the tap position and the standard turns ratio after switching.
7、Fast speed, test time for one set of data is 8 seconds.
8、Test results are not affected by fluctuations in the frequency and amplitude of the power frequency supply.
9、Built-in overcurrent protection, and protection against reverse connection of high and low voltage.
10、Can be fully controlled by the host computer for the entire testing process, saving data and printing test reports.
11、Test results are automatically saved, up to 99 can be saved.
12、The instrument has a built-in user manual, which can be consulted at any time.
