In the UK, this arrangement is most frequently employed.1 (especially in case of PNB (Protective Neutral Bonding, also known as TN-C-S PNB) when PME earthing isn’t used)).TN-C-S earthing system (or TN-C-S system) is a distribution system in which one live part of a power source is earthed, exposed-conductive-parts of an electrical installation are connected to the earthed live part of the power source in a head part of the electrical installation (from the power source) by PEN, PEM or PEL conductors, and in other part of . As demonstrated in the . ELECTRIC STATIONS.This paper presents safety analysis of TN-S and TN-C-S earthing system considering different sizes of cable and protective earthing conductor (PEC). This type of earthing is used in distribution systems in both Australia and New Zealand and is frequently referred to as multiple earth-neutral (MEN).In a TN-S system both the neutral and protective conductors are separate within the supply and within the installation. The installation earth and neutral are separate conductors.Purpose of Earthing. Where PME conditions apply, the returning current has two possible paths, through the combined conductor and the general mass of Earth.Tn-C-s system earthing. This will be useful to students on level 2 and 3 electrical installatio.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 . The Neutral and the protective earth are combined into a single conductor throughout the system.Earthing is the connection of the neutral point of a power supply system to the earth.The DNO’s maximum external earth fault loop impedance in these configurations is normally 0. For this purpose, touch voltage and electric shock calculations are presented. The earthing system design and implementation follow the Malaysian Standard MS IEC62305, MS IEC 60364-7-712:2020 and the regulations of the Energy Commission of Malaysia . Normally the means of earthing is provided from the supply cable metallic sheath or other separate supply conductor. This also makes it simpler and quicker to . This type of earthing is also known as multiple . USA / Canada – Uses TN-C for the feed from Transformer but uses TN-C-S within the structure at customer premises.A TN-C-S system, has a neutral channel from the main distribution equipment (power source) connected to the earth and earthing at a certain distance along neutral channels leading to consumers, usually referred to as Protective Multiple Earthing (PME). Detailed illustrations depict the transition from the .Figure 3: TN-C-S system with PME. If PME is not provided to PEN conductor any breakage of it may cause dangerous rise in potential of exposed-conductor parts and which may lead to shock hazards. Over the years, three main types of earthing systems have been developed – TN-C-S, TN-S and TT.
