How it works

The C31 LLT will indicate if a section of overhead line equipment (OLE) is de-energised and if not, what voltage is present.

Active Circuit

The second is an active circuit which is battery powered and it controls:the Red – Green lamp voltage indication. It also performs a system check, a lamp test and battery test every time the tester is turned on, and it warns if the calibration certificate is out-of-date, and it logs test activity for diagnostic purposes.The first is a passive circuit that is powered by the OLE voltage itself, which drives the meter pointer to indicate the precise voltage.

Independent Circuits

The Cotec LLT is two independent testers in one body. Each one is galvanically isolated from the other so that if one circuit should fail then the other indicator can be trusted to keep operating. Having two independent measuring elements, the user can be sure of the indicated condition as each one confirms the other.
