Primary current from 100 to 30000A
Ith up to 1000 Ipn
Cast-resin insulated
|
 |
Current transformers vacuum moulded in self-extinguishing epoxy resin for the measurement of AC currents from 100 to 30000A.
This range is also suitable for power generation. They have been designed to be installed in bus ducts between generator and transformer.
They enable very high performance to be achieved.
