Download Type Test

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.
