The Dangers of Misusing IEEE80: Ensuring Safety and Compliance
Title: Electrical Safety in Indian Metro Rail Projects: A Case Study
Several large-scale metro rail projects in India have come under scrutiny due to the violation of national and international safety practices. This article focuses on the case study of Chennai Metro Rail, designed by M/S SYSTRA RAIL, to shed light on the use of unreliable and non-compliant solutions in these projects. The main cause, as evidenced by tender documents, is the propaganda by software companies promoting IEEE80. The tender specifications and calculations provided in the documents highlight the use of illogical and non-scientific ideas. This article aims to raise awareness about the importance of proper electrical safety practices in Indian metro rail projects.
Note: The article will continue with the description and analysis of the case study, highlighting various issues and providing recommendations for improving electrical safety standards in India.

Title: Major Projects in India Neglect Safety and Reliability Standards
Several large-scale projects in India are being criticized for their failure to comply with national and international safety and reliability practices. One such example is the use of Earthing in metro rail projects, specifically in Chennai. This article examines the tender specifications for the Chennai Metro Rail project, highlighting the flaws in the approach and the need for adherence to proper standards.
Subheading 1: Questioning Propaganda and Compliance
One of the main issues leading to the use of unreliable and non-compliant solutions in metro railway projects is the promotion of IEEE80 by software companies. This propaganda has influenced decision-making, resulting in illogical and non-scientific ideas being implemented, as evidenced by the tender specification for Earthing in the Chennai Metro Rail project.
Subheading 2: Inadequate Tender Specifications
The tender specifications for Earthing in Chennai Metro Rail project, designed by M/S SYSTRA RAIL, raise several concerns. The specifications can be downloaded from provided links, allowing for a more detailed analysis. It is important to note that the GPR (Ground Potential Raise) mentioned in the tender calculations indicates a significant voltage increase due to earth faults in low voltage powerlines.
Subheading 3: Lack of Standard Compliance
While the tender claims to meet Indian standards, it incorporates multiple standards without clear recommendations. This contradiction raises questions about the reliability of the specified solutions. A video presentation on the subject, with over 250 participants, sheds further light on the issue.
Subheading 4: Soil Resistivity and Earth Enhancing Compounds
The Chennai Metro Rail project employs tons of earth-enhancing compounds to compensate for the highly corrosive soil with a resistivity of 30 ohm-M. However, using such compounds may actually increase electrode corrosion. Additionally, improper drawings and design choices further raise doubts about the adherence to standards.
Subheading 5: The Problem with IEEE80 Propaganda
The tender specifications reveal a reliance on IEEE80 as a universal solution for all earthing problems in India, regardless of the operating voltage. However, it is crucial to understand that IEEE80 is a guide, not a standard or recommended practice. By misrepresenting IEEE80, certain software companies have damaged the reputation of this standard.
Subheading 6: Violations and Negligence
The Chennai Metro Rail project’s tender specifications violate safety regulations upheld by the Government of India. Such erroneous designs, once implemented, are difficult to rectify, jeopardizing the reliability of the entire metro rail system. It is essential for all designers to strictly follow Indian standards and safety regulations to prevent future mistakes.
Subheading 7: Overlooking Indian Standards
India has its own comprehensive electrical safety standards, such as IS 732 (based on IEC 60364). Unfortunately, a majority of industrial and commercial low-voltage installations in India fail to implement these standards properly. Instead, there is an inclination to follow American, European, and British standards, neglecting the better standards set by Indian regulatory bodies.
The improvement of electrical safety in India relies on a better understanding of propaganda surrounding standards. Electrical engineering communities need to prioritize the implementation of fundamental safety measures as per Indian standards. By doing so, the integrity and reliability of major projects can be ensured, fostering a safer future for all.
Summary: The Dangers of Misusing IEEE80: Ensuring Safety and Compliance
Several large-scale projects in India are using unreliable and non-compliant solutions in subjects related to safety and reliability. A classic example is the use of earthing in metro rail projects. These projects are being influenced by propaganda from software companies promoting IEEE80, which is not an IEEE standard or recommended practice. The tender specifications for these projects violate national and international practices and are a collection of fancy sentences from various standards. The use of earth enhancing compounds in highly corrosive soil further adds to the issues. It is important for designers to follow Indian safety regulations and for the electrical engineering community to understand and implement fundamental safety measures based on Indian standards. Electrical safety in India can only improve if these propagandas are challenged and the correct standards are followed.
Frequently Asked Questions:
Frequently Asked Questions about Misuse of IEEE 80
Frequently Asked Questions – Misuse of IEEE 80
1. What is IEEE 80?
IEEE 80 is a standard developed by the Institute of Electrical and Electronics Engineers (IEEE). It provides guidelines for the design, installation, and maintenance of grounding systems in electrical installations for safety purposes.
2. What constitutes misuse of IEEE 80?
Misuse of IEEE 80 refers to instances where the guidelines and recommendations outlined in the standard are not followed during the design, installation, or maintenance of grounding systems. It can include using incorrect materials, improper system configurations, or neglecting maintenance practices.
3. What are the potential consequences of misusing IEEE 80?
Misusing IEEE 80 can lead to various consequences, ranging from safety hazards to equipment malfunction. Improper grounding can result in electrical shocks, increased risk of fire, and damage to sensitive electrical equipment. Additionally, noncompliance with industry standards can result in legal liabilities and violations.
4. How can misuse of IEEE 80 be prevented?
To prevent the misuse of IEEE 80, it is essential to ensure that qualified professionals with knowledge of the standard are involved in the design, installation, and maintenance of grounding systems. Regular inspections, adherence to proper materials and techniques, and staying updated with the latest revisions of the standard can significantly reduce the risk of misuse.
5. Are there any specific industries or applications where misuse of IEEE 80 is more common?
Misuse of IEEE 80 can occur in various industries and applications that require electrical installations.
