I
IET 01
IET 01:2024 is a non-statutory IET standard and technical specification for Open combined Protective and Neutral conductor Detection Devices used with EV charging equipment. It sets out definitions, requirements and tests for how discrete or integrated OPDD functions should respond to open PEN conductor faults.
Internal PE Breakage
Internal PE breakage refers to a charger design where the charger has a means of interrupting or isolating the protective earth path internally as part of its response to a detected PEN fault condition.
IT Earthing
IT earthing is an arrangement where the supply has no direct connection to earth or is connected through a high impedance. It is normally assessed during product selection, circuit design, installation verification and maintenance of EV charging equipment.
