What Is A Split Core CT?

One main feature of a split core CT​ is its convenient installation. Users do not need to cut cables or shut down the power supply during setup. This reduces downtime and improves safety, especially in existing power systems. Another advantage is electrical isolation, which separates high‑voltage primary circuits from low‑voltage secondary circuits. This design protects measuring instruments and workers from electric hazards. Split core CTs also offer stable accuracy and are available in different precision classes to support monitoring, metering, and protection applications. They are lightweight and compact, making them suitable for use in narrow spaces such as distribution boxes and control cabinets.

What Is A Donut Current Transformer?

A donut current transformer, also widely known as a toroidal current transformer (CT), is a specialized device engineered for precise alternating current (AC) measurement and circuit protection in electrical systems. Distinguished by its solid, ring-shaped core structure, the donut CT features no discrete primary winding. Instead, the conductor carrying the measured current passes directly through its central aperture, functioning as a single-turn primary. This unique design integrates the primary conductor into the device's core, eliminating the need for additional winding connections and streamlining installation in both new constructions and industrial setups.

What Is A Core Balance Current Transformer (CBCT)?

A Core Balance Current Transformer (CBCT), also known as a Zero Sequence CT or Residual Current Transformer, is a special type of current transformer used primarily for earth fault protection in electrical power systems. Unlike conventional current transformers that measure the current of individual conductors, a CBCT encloses all three phase conductors (and sometimes the neutral) within a single magnetic core.
