Differential protective transformers

Choosing carefully the magnetic material an the correct ampereturns of the secondary winding the current transformer illustrated in the previous pages, can be made compatible with all technical data that the devices used in the differential protection field require, for a right working (differential relays, setting values etc.)
The minimum differential current to be picked up is 20 mA.
The current transformers can be built with one or two secondary windings, one for protection and one for test.
Current transformers with housing self-extinguishing materials case or fully embodied in resin can be realized.
