Grounding System Assessment Program

The Grounding System Assessment Program is designed to promote maximum operating reliability of the facility electrical system along with the sensitive electronic equipment such as computer equipment, PC's, workstations, LAN/WAN equipment/systems, POS, and telecommunications equipment while providing for a safe working environment.

The Grounding System Assessment Program is not only a stand alone service but is also part of the Power Quality and Power Management Programs.

The Grounding System Assessment Program is used for new construction acceptance certification, facility remodel acceptance testing, expansions or upgrades to computer rooms, network systems, office PC's, or other investments in new electronic technology advances.  This proactive program is used to gather the present grounding system characteristics.  This provides the necessary information to determine if the present grounding system can support the proposed equipment or changes in a safe manner, along with promoting maximum performance and reliability for the sensitive electronic equipment.

There are many factors that determine how long the Grounding System Assessment Program will take to complete depending on the size of the facility, the scope of the work, and the program category selected.  The Grounding System Assessment Program is divided into three phases.  The first phase is the Grounding Survey.  The average survey can typically be completed in one day.  Once completed, all the findings are documented in a report along with recommendations for any changes that may be required.  The second phase is to either support, assist, or perform the changes that may be required.  The third phase is a verification of any changes made.  This is performed to insure that changes have been completed correctly and that no hidden deficiencies now surface due to the changes.

The Grounding Survey is made up of three distinct services.  These services are earth system testing, bonding method evaluation and testing, and equipment grounding testing.

The earthing system testing encompasses inspecting and testing the electrical systems connection to earth.  The inspection and testing process examines the earthing system from the standpoint of the National Electrical Code, industry electrical standards (e.g. Institute of Electrical and Electronics Engineers), personal safety requirements (e.g. OSHA), manufacturers procedures, and internal company practices.  The testing process covers the earthing system, methods, and connection to the electrical service.  The earthing system evaluation provides the necessary information in determining if the earthing system can properly support the electrical system.

The bonding method evaluation encompasses inspecting and testing the electrical system bonding practices.  The bonding evaluation begins at the electrical service entrance and continues on to the equipment.  The inspection and testing process examines the electrical system bonding practices from the standpoint of the National Electrical Code, industry electrical standards (e.g. Institute of Electrical and Electronics Engineers), personal safety requirements (e.g. OSHA), manufacturers procedures, and internal company practices.  The testing process covers the electrical service bonding methods, and electrical distribution system bonding methods.  The bonding evaluation provides the necessary information in determining if the bonding practices can properly support the electrical system.

The equipment grounding system testing encompasses inspecting and testing the electrical systems equipment grounding practices.  The inspection and testing process examines the electrical systems grounding system from the standpoint of the National Electrical Code, industry electrical standards (e.g. Institute of Electrical and Electronics Engineers), personal safety requirements (e.g. OSHA), manufacturers procedures, and internal company practices.  The testing process covers the electrical service grounding methods, electrical distribution grounding system, and the branch circuit equipment grounding system.  The equipment grounding system evaluation provides the necessary information in determining if the equipment grounding system can properly support the electrical system and connected equipment.
