Understanding Earthing System in Malaysia

Understanding the Earthing System

The earthing system in Malaysia plays a crucial role in ensuring electrical safety and stability. Technologies are improving, and electrical systems are getting more complicated. Hence, it’s crucial for electrical engineers and others interested in the field to grasp the basics of earthing.

In this guide, we’ll look closely at Malaysia’s earthing system. We’ll observe how designers create it and how experts implement it. We’ll also go through why it plays a crucial role in maintaining electrical supply and setups’ safety. Proper earthing ensures the safety of occupants and equipment. It reduces the risk of electrical accidents, electrocution and fire. Statistics show that buildings with effective grounding experience 63% fewer electrical accidents. On the other hand, inadequate grounding is responsible for 30% of eletrica fires. Investing in a reliable earthing system reduces the likelihood of fires by 70%.

To comprehend the earthing system in Malaysia, it is vital to grasp the concept of earthing itself. Earthing, also known as grounding, involves connecting electrical systems and equipment to the Earth’s conductive surface. Its primary purpose is to provide a path of least resistance to electrical faults. It ensures to dissipates excess electrical energy safely into the ground.

Lightning & Earthing System/Standards in Malaysia

In Malaysia, where tropical weather reigns, thunderstorms bring both stunning beauty and the risk of lightning strikes. To ensure the safety of people and property, it’s crucial to have an effective lightning protection system (LPS). This means understanding and following the regulations that govern such protection solutions. The MS IEC 62305 standard, endorsed by MOSTI in 2007, provides comprehensive guidelines for designing, installing, and maintaining effective lightning protection systems.

Components of the Earthing System

In Malaysia, the earthing system consists of several essential components. These include:

Earth Electrode: The earth electrode, typically made of copper or galvanized steel, establishes a direct connection between the electrical system and the ground.

Earth Continuity Conductor: This conductor ensures a low-resistance path for electrical currents, connecting the various metal parts of the electrical installation to the earth electrode.

Main Earthing Terminal: Acting as the central point for earthing, the main earthing terminal facilitates the connection between the earth electrode and other components of the earthing system.

Earth Fault Protection Devices: These devices, such as residual current devices (RCDs) and earth leakage circuit breakers (ELCBs), detect electrical faults and promptly disconnect the power supply to prevent harm to individuals and equipment.

Earthing Standards and Regulations in Malaysia

Maintaining uniformity and ensure electrical safety across the country, Malaysia adheres to specific earthing standards and regulations.

The Malaysian Standard MS IEC 60364-7-712:2020 outlines the requirements for earthing systems in electrical installations, covering aspects such as design, materials, testing, and maintenance. Additionally, regulatory bodies such as the Energy Commission of Malaysia (Suruhanjaya Tenaga) monitor compliance with these standards to safeguard public safety.

Types of Earthing System in Malaysia

Malaysia uses different earthing/grounding systems for different electrical installations. These are:

TN-C-S System: The combined neutral and protective conductor (PEN conductor) earths this system.

TN-S System: This system prevents accidental neutral breaks by separating the neutral and protective conductors.

TT System: The TT system protects electrical installations with local earth electrodes.

Importance of Earthing in Malaysia

Malaysia’s electrical infrastructure needs a well-designed and implemented earthing system. Key reasons:

Electrical Safety: Proper earthing prevents electric shocks, fires, and equipment damage.

Power Quality and Reliability: A strong earthing system reduces electromagnetic interference (EMI) and voltage fluctuations, stabilizing power supply and protecting sensitive equipment.

Compliance with Standards: Earthing standards and regulations are essential for legal compliance, certification, and electrical installation longevity and efficiency.

Maintaining the Rhythm: Ongoing Vigilance in Lightning Protection

In the realm of lightning protection, the grounding system is akin to the bassline of a musical masterpiece—it must remain consistent and reliable to ensure the overall harmony of safety. Regular inspection and maintenance are the keystones of a robust lightning protection strategy. TAKO’s commitment to safety extends beyond installation, embracing a culture of continuous vigilance.

A lightning protection system is not a static entity; it evolves with the building it protects. It requires a symphony of elements to perform seamlessly, from risk assessment to the meticulous upkeep of every component.

By adhering to the MS IEC 62305 standard, TAKO ensures that each lightning rod not only attracts lightning but also creates ionized paths for safe discharge. This ongoing process is critical, as lightning can strike with little warning, and only a well-maintained system can provide the necessary defense.

  • Inspection: Regular checks to identify any wear or damage.
  • Maintenance: Prompt repair or replacement of faulty elements.
  • Testing: Verification that the system meets performance standards.
  • Documentation: Keeping detailed records for accountability and improvement.

Where is TN-C-S earthing used? 

TN-C-S earthing is used in many countries, especially in Europe, for low voltage networks. It is a system in which the neutral and protective functions are combined in a single conductor (PEN) in part of the system, and separated in another part of the system (PE and N). This allows the single-phase loads to be supplied by phase and neutral, and the exposed-conductive-parts to be connected to a separate earth system.

Which type of earthing is used in industries?

The type of earthing used in industries depends on the nature of the load, the supply system, and the safety requirements. Generally, TN systems are preferred for industrial applications, as they provide low impedance fault paths and fast disconnection of supply. However, some industries may use TT or IT systems for specific reasons, such as isolation, continuity, or overvoltage protection

Which type of earthing is used for domestic?

The type of earthing used for domestic installations depends on the country, the supply system, and the local regulations. In the UK, for example, TN-C-S (PME) is the most common type of earthing for domestic premises, as it provides a reliable and economical earthing system. However, some areas may use TT or TN-S systems, depending on the availability and quality of the supply neutral.

Where is solid earthing used?

Solid earthing, or effective earthing, is a term used to describe the earthing of the neutral point of a power source (e.g. generator, transformer, etc.) directly to the earth, without any intentional impedance. Solid earthing is used to limit the voltage rise of the system during a fault, and to provide a low resistance path for the fault current. Solid earthing is commonly used for low and medium voltage systems, where the fault current is limited by the system impedance.
