Grounding System Audit
Detailed analysis of incoming power and grounding integrity identifies distinctive problem locations and provides recommendations to enhance overall system performance.
Few years ago, it would have been rare for anyone to talk about the importance of low resistance grounding and bonding. Low resistance grounding is now critical as low impedance electrical grounding is essential for safety and protection of substation equipment, safety of personnel inside and around electrical substations, and also for the effective lightning protection system. A well-designed ground grid is the backbone of all industrial, data centers and utilities facilities. It is the basis for any facility's power quality assurance program.
Benefits
Grounding System Audit provides a detailed analysis of incoming grounding integrity and its effect on connected devices and internal power systems. Audit findings pinpoint specific problem areas and provide fixes that improve overall system performance.
Grounding tests fall into 2 categories:
New Substations: to ensure your installation meets grounding specifications, as your electrical system needs a low impedance path to ground for protecting people and equipment
Existing Substations: to ensure it still meets grounding specifications and the grid resistance and grid potentials are comparable to the ground grid design calculations, because grounding systems deteriorate and so does their performance.
A full audit (measurements, modeling and design) will identify ground faults and deterioration of the ground grid, connectors, power quality deficiencies and improve overall system performance.
Comprehensive scope of work An audit begins with a review of documentation of system grounding installation. Using state of the art test equipment (on either an energized or a de-energized substation), a careful review of the installation is then performed on the following:
Reporting and recommendations
Upon completion, a thorough report including detailed implementation recommendations to improve grounding related problems and associated cost is provided.
Upgrade services
TEEBA can assist you with implementation of recommendations to enhance productivity. Our time-tested expertise in this area can help revitalize electrical system efficiency to a level you may have considered to be out of reach.
Maintenance
TEEBA, as well International Electrical Testing Association (NETA) Standards, highly recommends that the Grounding System Audit be performed annually as part of a comprehensive maintenance program.
