WebApr 27, 2024 · PME is a TN-C-S system, where the neutral and earth functions are combined in one conductor (the PEN conductor) on the supply side of the installation. The PEN conductor is referenced to Earth in multiple positions with Earth electrodes, as illustrated in Fig 1. WebTN-C: TN-C describes an arrangement where a combined Protective Earth-Neutral (PEN) is connected to the earth at the source. This type of earthing is not commonly used in …
In low-voltage networks, which distribute the electric power to the widest class of end users, the main concern for design of earthing systems is safety of consumers who use the electric appliances and their protection against electric shocks. The earthing system, in combination with protective devices such as fuses and residual current devices, must ultimately ensure that a person doe… WebJun 22, 2024 · The TN-C system requires an effective equipotential environment within the installation with dispersed earth electrodes spaced as regularly as possible since the PEN conductor is both the neutral conductor and at the same time carries phase unbalance currents as well as 3 rd order harmonic currents (and their multiples).
