Substation Earthing

At ARA Electrical Services, we specialise in the design and engineering of comprehensive substation earthing studies to ensure the safety and reliability of your electrical infrastructure.

Our team of experienced engineers conducts meticulous assessments to identify potential hazards and optimise the protection of your substation and personnel.

Our substation earthing studies involve a detailed analysis of the earthing system design, including soil resistivity testing and fault current calculations. Our engineers evaluate the existing earthing system’s performance, measuring impedance and ensuring it meets the required safety standards. We also assess potential touch and step voltages to mitigate the risk of electric shock and ensure safe operation.

Using advanced modelling software and simulation tools, we design and implement customised earthing solutions tailored to your substation’s specific needs. This includes the selection of appropriate earthing materials, grid layout optimisation, and ensuring compliance with relevant industry standards such as IEEE 80 and IEC 61936.

Key aspects of our substation earthing study include:

  • Soil Resistivity Measurements: Conducting soil resistivity tests to determine the soil’s electrical characteristics, which are critical for designing an effective earthing system.
  • Fault Current Analysis: Calculating fault currents to understand the potential impact on the earthing system and ensure it can safely dissipate these currents.
  • Impedance Measurements: Measuring the impedance of the earthing system to ensure it is within acceptable limits for safe operation.
  • Touch and Step Voltage Analysis: Assessing touch and step voltages to identify and mitigate the risk of electric shock to personnel.
  • Earthing Grid Design: Designing an earthing grid that optimises the layout and selection of earthing conductors and electrodes to achieve low impedance and high reliability.

With ARA Electrical Services, you can trust that our engineering expertise will enhance the safety and efficiency of your substation’s electrical systems. Our commitment to excellence in design and engineering ensures that your earthing system not only meets but exceeds industry standards.
