CTSB0508 Split Core Current Transformer
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.
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. Features:
- Primary Conductor opening – 50mm(2.0″) x 80mm(3.2″).
