Current transformer JK-G

encapsulatedprotectionclosed

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 standardized 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 aluminum 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 realized 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. Features • Degree of protection possible up to IP 65 (IP 53) • Suitable for up to 4 (2) current transformer cores, dependent on ratio and class • 4 different transformer hole diameters: 85 mm, 115 mm, 145 mm, 225 mm
