Digital ratiometer for single and three-phase transformers

To calculate the ratios, the DTR8510 uses the IEEE C57.12-90-2006 measurement method.
To ensure greater user safety, the tests are performed by excitation of the primary and measurement on the secondary.

Advantages of the DTR8510:
- NiMH battery life of up to 10 hours
-   Automatic calibration and balancing  saves considerable time  No adjustments required.
- Low-voltage test  Prevents errors due to saturation of the CTs when they are tested at high
  voltages.
- Digital display  display of ratios, winding direction - % deviation in relation to rated values - 
 excitation current. The bargraph indicates the progression of auto-calibration and
  measurement.
- Degauss function to eliminate magnetic effects and improve accuracy
