The live-line working method is a technique that allows for the maintenance, repair, or construction of electrical infrastructure or installations while keeping the electrical voltage active and adhering to worker safety regulations.
A regulatory framework, defined in Decree 82-167 of February 16, 1982, for energy distribution infrastructures, mandates that live-line work must be particularly guided by reference documents (CET, FT).

Voltage Levels
Three defined levels of work
The method of working <<remotely>> (BT-HTA-HTB): the operator is at ground potential and works using insulating poles.
The method of working <<in contact>> (BT-HTA): The operator works with insulating gloves.
The method of working <<at potential>> (HTA-HTB): The operator works at phase potential.
