Standard voltage transformers, 2-stage
EPRO Gallspach GmbH’s testing technology devices are custom built. To give you an overview of the possibilities, you will find below some examples of oil insulated, 2-pole medium voltage transformers that we have already successfully implemented.
| Model | Insulation & Execution | max. primary voltage | Range | Accuracy | appr. weight |
|---|---|---|---|---|---|
| NVOS 30bc | oil, single pole | 35 kV | 20 - 120 % x Un | 0,005%; 0,5min (+/-) | 200 kg |
| NVOD 10bc | oil, double pole | 10 kV | 20 - 120 % x Un | 0,003%; 0,3min (+/-) | 200 kg |
For a better understanding of these special devices, please find below the calibration reports and a comparison between NVOS 30 and NVOS 30bc:
