Cable current transformers Indoor and outdoor operation JK JKS / JKS-S JK-G / JKS-G JKF JLD Current transformers JK 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 transformers are designed according to applicable national and international standards. Designs that meet customer- specific standards are possible on request. 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 up to 5000 A can be measured. A specific core padding and the complete casting of all active parts in polyurethane (PUR) ensures that the magnetic properties, and therefore the class accuracy, remain constant for decades. The standard secondary terminal enclosure permits a housing degree of protection up to IP 20. Optionally, secondary terminals can be integrated in a terminal box, providing a housing degree of protection of up to IP 65. Thanks to a wide range of geometric dimensions the cable current transformer can be adapted to customer requirements. Applicable installation options are also available in various designs, as well as any type of installation position.

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. The split core current transformers are opened and closed with M8 screws located on the sides. The secondary terminals are routed in a terminal box to M6 cast sockets. The connection to the secondary circuit can be realised with appropriately sized cable lugs. Type JK-G The type JK-G current transformer is a single unit. Up to 4 cores are possible, depending on the type. An IP 65 degree of protection is achieved here. With regards to installation, only vertical mounting with + / – 60° deviation for reasons of outdoor reliability. Type JKS-G The type JKS-G current transformer has a split core. Maximum of two cores possible, dependent on the translation and class. An IP 53 degree of protection is achieved here. With regards to installation, only vertical mounting with + / – 30° deviation for reasons of outdoor reliability.

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 transformer part. Degrees of protection can optionally be provided between IP 20 and IP 65. Bar current transformers of type JLD can be designed for outdoor / outdoor, outdoor / indoor and indoor / indoor applications. The corresponding wall bushing and insulation type of the current transformer part must be appropriately selected. A silicone-shielded wall bushing with a current transformer part cast in outdoor-resistant casting resin is used for outdoor applications. The current transformer parts are cast in polyurethane (PUR) for indoor applications. A special core padding ensures that the magnetic properties are not affected by thermal compression stresses. This allows the class accuracy to remain constant over decades.
