Indoor (air or oil immersion)
Primary intencity from 50 to 5000 A
Inner diameter Up to 700 mm
Heavy insulation 0.75/4 kV
Measurement and protection
|
 |
Used for the measure of AC currents from 50 to 5000 A.
Air mounted (impregnated) or oil immersed in power transformers.
Individual mounting as several independent transformers, or as a plug & play assembly.
Each transformer is individually tested, then as a whole in the assembly work.
Flexible solution that can be customized to any client configuration.
