For existing facilities we conduct a site assessment of the existing earthing protection systems. A detailed report follows with a critical appraisal of the condition, configuration and specification of the existing on site earthing systems. Addressing:
We provide substation earthing studies & design systems to comply with IEEE80 standards. We also provide modelling capacity for touch and step voltage.
Safety is the primary function of an earthing studies system. They provide a common ground reference point for all electrical equipment, and assist in the operation of overcurrent devices during faulty conditions. A functioning and well maintained earthing system is essential for the safe operation of electrical distribution systems.
- The condition of the earthing systems for each building
- Compliance of the existing earthing systems in line with the BS 7430:2011 Code of Practice for protective earthing of electrical installations and the National Rules for Electrical Installations, Fourth Edition ET101:2008
- Alterations and cost estimates to upgrade the existing earthing systems to comply with current Standards
FEATURED CASE STUDY
Gas Terminal - Earthing Studies
We worked closely with another well known engineering company to provide specialist earthing studies for a Gas Terminal in Co. Mayo. The Terminal is an on-shore gas processing facility that will provide up to 60% of Ireland’s gas at peak supply. Premium Power conducted an engineering study to determine if earthing grids installed at the facility were compliant with IEEE80.
”"During our earthing study we modelled the earth grids and were able to identify that the earth grids designed were within the limits imposed by IEEE80. These studies are of critical importance in the design of substations and ensure the safety of workers both within and outside of the substation fence boundary"Alan O'KellyDirector
