Earth Ground Testing
Poor grounding not only contributes to unnecessary downtime, but a lack of good grounding is also dangerous and increases the risk of equipment failure. Ground is defined as a conducting connection, whether intentional or accidental between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth. When talking about grounding, it is actually two different subjects: earth grounding and equipment grounding. Earth grounding is an intentional connection from a circuit conductor, usually neutral, to ground electrode placed in the earth.
Equipment grounding ensures that operating equipment within a structure is properly grounded. These two grounding systems are required to be kept separate except for a connection between two systems.
The purpose of a ground besides the protection of people, plant and equipment is to provide a safe path for dissipation of fault currents, lighting strikes, static discharges, EMI and RFI signals and interference. It is thus of outmost importance to ensure your grounding system is up to standard.
