The CTSB series of split-core current transformers are designed for the measurement of AC currents carried by large primary conductors or substation BUS bars.The split-core design permits the fast and easy installation on large primary conductors/ substation BUS bars without requiring that the primary conductor be taken offline and disconnected for CT (current transformer) installation.
The CTSB series of split-core current transformers feature a high performance magnetic core for highly accurate AC current measurement. The robust packaging features;

• Tight fitting mating magnetic core halves,
• Hardware to secure closure of the current transformer after installation, and
• Hardware to secure the position of the primary conductor within the current transformer opening window.

These features insures consistent and highly accurate AC current measurement performance over the life of the current transformer installation.
The robust CTSB split-core current transformer design, manufactured in an ISO9001 certified manufacturing facility, insures many years of defect free operation backed by a strong product warranty of 36 months.
