What is TN-S Earthing System?
This video dives deep into the complex realm of TN-S Earthing Systems. This is not just another basic tutorial-this video aims to provide you with an advanced understanding of how TN-S Earthing Systems work, from purpose to design, and how they serve as a cornerstone for electrical safety.
What Will You Learn?
1. Purpose of TN-S Earthing System: Grasp the fundamental objective of the TN-S Earthing System-its role in electrical safety. Learn how it establishes a low-resistance pathway, described by Rearth, for fault currents to safely dissipate into the Earth.
2. Designing Parameters for TN-S Earthing System: Go beyond the layman's approach and delve into the technical specs and codes that guide the design. This section caters to those who appreciate terms like "soil resistivity (ρ)" and "fault current (Ifault)".
3. Checking Adequacy of Your Earthing System: A step-by-step guide to DIY checks you can perform to assess the integrity of your TN-S Earthing System.
4. Comparison: TN-S vs. TNC vs. TN-C-S vs. IT: How do other systems measure up against TN-S? A comparative analysis that includes pros, cons, and appropriate use cases for each system.
Crucial Parameters for TN-S Earthing Design
While designing a TN-S Earthing System, it’s vital to consult specific electrical codes and standards such as:
• IS 3043 (2018) for India
• BS 7430 - 2011 for International Applications
• IEEE 80 - 2013 for AC Substation Grounding
Consider soil conditions. A high soil resistivity ρ might require specialized earthing methods like chemical earthing to maintain Rearth within permissible limits.
Larger electrical setups will need an extensive TN-S Earthing System, often demanding conductors with larger cross-sectional area A and lower resistivity material.

In such cases usually pipe earthing or rod earthing is used.
Do you have any courses

Connect to a metal water pipe or structure? Geez! Good recipe for disaster.

Based on the IEEE Std 80-2013 guidelines, you can refer to section 9.6, which states: "Conductors of adequate ampacity and mechanical strength should be used for the connections between: a) All ground electrodes, such as ground grids, rod beds, ground wells, and, where applicable, metal, water, or gas pipes, water well casings, etc." This clearly indicates that metal water pipes can be used for grounding connections, provided the conductors have adequate ampacity and mechanical strength.

It's not because something is up to spec that it's desirable or even good. This is a major risk in multiple situations, with many associated accidents, and shouldn't be promoted.
