Cable current transformers Indoor and outdoor operation JK JKS / JKS-S JK-G / JKS-G JKF JLD Current and voltage - our passion

Current transformers JK The transformers are designed according to applicable national and international standards. Designs that meet customer-specific standards are possible on request. Cable current transformers type JK are used in indoor switchgears. They transform high currents up to 5000 A into standardised values for meters, measuring and protection devices. The cable current transformer is designed for installation on fully insulated medium and high voltage cables or for installation on medium and high voltage bushings. This enables a space-saving system design. Primary currents of...

Current transformers JKS / JKS-S Split core cable current transformers of type JKS / JKS-S are used in indoor switchgears. They transform high currents up to 3000 A into standardised values for meters, measuring and protection devices. The split core cable current transformer is designed for subsequent installation on fully insulated medium and high voltage cables. This enables retrofitting of existing systems in a simple manner. Primary currents of up to 3000 A can be measured. A specific core padding ensures that the magnetic properties, and therefore the class accuracy, remain constant...

Current transformers JKF Type JKF cable current transformers are used in outdoor switchgears. They transform high currents up to 4000 A into standardised values for meters, measuring and protection devices. The outdoor version of the cable current transformer is designed for installation on fully insulated medium and high voltage cables or for installation on medium and high voltage bushings. This enables space-saving system design. Primary currents of up to 4000 A can be measured. A specific core padding and the complete casting of all active parts in cycloaliphatic epoxy resin suitable...

Cable current transformers of type JK-G / JKS-G are used in outdoor applications for medium or high voltage systems. They are mounted over the high or medium voltage cable and transform currents up to 3000 A into standardised values for meters, measuring and protection tasks. The cable provides the insulation against high voltage in this transformer type and also represents the primary winding of the current transformer. The current transformer itself is installed on a frame or crossmember over the cable. The active parts are cast in a polyurethane resin protected by an aluminium housing....

Current transformers JLD (12 –170) kV Bar current transformers of type JLD are used in indoor and outdoor applications for medium or high voltage systems. They transform currents up to 5000 A into standardised values for meters, measuring and protection devices. Bar current transformers are typically used in wall, floor or ceiling openings. They consist mainly of a wall bushing and the coupled current transformer part. The wall bushing provides the insulation against high voltage and also represents the primary winding of the current transformer. Up to 5 cores can be included in the current...
