Portable, split-core HFCT sensors are used when the earth connections of the HV cable are outside of the cable box.

The sensors can also be installed inside the de‑energised and isolated cable boxes of switchgear, transformers or rotating machines for temporary testing or monitoring if the earth connections are not available outside the cable box (requires an outage).
