Split-core current transformers (CTs) allow for easy measurement of individual conductors within an electrical distribution panel. Each CT can be "split" and attached without disconnecting a conductor from it's respective breaker. These CTs are available in a wide variety of physical sizes and amperage ratings to fit any installation setting.
Rope CTs are excellent for bus-bars and large switch-gear applications. Self-powered rope CTs are flexible and easy to install with a fixed current rating of 4800A and will not be accurate below 50A.
Solid Core DC-CT
A current transformer for those focused on high efficiency DC consumption sources, solid-core DC CTs are typically used for new wiring and permanent installation. To install them, the power must be turned off, the conductor disconnected, and then threaded through the CT window.
