Oil-Insulated Current Transformers (CT) up to 800 kV
GE’s OSKF have been designed for a 30 year lifetime and, thanks to the profound technical concepts, many well out-live this service life. The oil is hermetically sealed from the air by a stainless-steel diaphragm assembly and all external parts are of corrosion-resistant material.
