Earthing & Bonding Services
Earthing & Bonding For Tram & Railway Systems
Mac’s Electrical Limited we have extensive experience in the installation of earthing and bonding for tram and railway systems. Our expertise ensures safe and compliant electrical grounding, protecting against electrical shocks, corrosion and electromagnetic interference.
Earthing & Bonding For AC Traction Systems
AC traction systems require effective earthing and bonding for safe operation. Key technical considerations include:
- Protection Against Electrical Shocks – Proper earthing prevents indirect contact hazards, reducing the risk of electrical injuries.
- Electromagnetic Interference (EMI) Control – Effective bonding reduces EMI, preventing interference with signalling and communication systems.
Earthing & Bonding for DC Traction Systems
DC traction systems require additional protection due to the nature of the electrical current. Our expertise includes:
- Protection Against Electrical Shocks – Compliance with safety standards for indirect contact situations.
- Stray Current Control & Corrosion Protection – Managing stray currents to prevent damage to infrastructure and underground services.
- Electromagnetic Interference Mitigation – Minimising EMI in circumstances where sensitive equipment may be affected.
Testing Methods
Knowledge has been gained about which test methods are appropriate for a given earth mat installation type / location and different points in the construction programme.
To achieve a consistent set of assurance records the types of tests, the points in the programme where the test is to be undertaken plus the contents of reports and certificates needs to be specified. It has also been found that the choice of test instrument is important to enable a consistent reliable result.
Mac’s Electrical Limited use the Megger MOM2 micro-ohm test meter.
Megger's MOM2 is a high accuracy, low resistance micro-ohmmeter commonly used for testing earthing resistance, low, medium and high voltage breakers, bus bar joints and other high current links.
