3 Phase Transformer Test Equipment To Monitor Current Voltage
The product could do the test of three phase combined transformers, at the same time it can provide three phase test voltage and current for the three phase combined transformer. Frequency and phase of the voltage and current could be adjusted
Highlight:
- Auto test of the error, auto saving of the error, and auto rounding of the error
- Adopt 320×240 matrix LCD, large active area, with long life back lightning.
- Auto sampling according to the requirements of the JJG314-1993 and JJG314-1994
- Auto detect the polarity and transformation ratio mistake, and auto change of the range
- Automatic and manual operation
- It makes the paperless operation possible from testing to the report printing and the certification of inspection with PC software.
- The system could monitor the current and the voltage, and it also has the function of positive and negative going motion interlocking, rotation limitation and protection.
- Under the rating power, the distortion factor of the voltage and the current: ≤1%, the output is stable and the point sort is quick and convenient.
- The output adjustment accuracy 0.5‰, which solves the problem of the point 1.0% that is difficult to adjust in CT measuring.
