Scope

IEC TR 63436:2026 explains the setting parameters of insulation monitoring devices (IMDs) and how to interpret these measurements through plotted curves. Some examples of injection methods are also proposed.
The examples given in this document consider the situation of an insulation fault in an installation or equipment (motors, enclosure, cables, etc.) creating a resistive path to earth and calculate the touch voltage. It does not consider a person making direct contact with a live conductor in an IT grid.
