Electrical Ground Testing

It allows uncontrolled electricity to go to the ground instead of causing a fire or damaging a building.

Electrical ground testing.

Basics of grounding system design. The measurement of ground resistance for an earth electrode system is very important. A ground rod is an important part of an electrical system. Electrical installation condition report.

Electrical circuits have a separate ground or earth circuit that provides an alternate low impedance path for electricity to safely reach the ground in case of accidental physical contact. Purpose method testing ground bond and ground continuity tests are designed to check the ground connection on a product or system. Protective or safety grounding systems. Built to withstand an entire spectrum of ground testing methods fluke s family of earth ground testers have been designed to be accurate safe and easy to use.

It should be done when the electrode is first installed and then at periodic intervals thereafter. The standard answer to nec requirements is to drive a second rod and call the job done. Apply a current to the ground point of a product or system. This ensures proper grounding.

Ground testing is used to measure the performance of this circuit and check if it meets requirements. How you ensure you have a proper ground. Browse our top selling 1623 2 geo earth ground resistance meter 1625 2 geo earth ground tester and the 1630 ground resistance meter today. The impact of lightning strikes on grounding systems.

The end user would use a test instrument and probes to first inject a current into the earth between a test electrode and a remote probe measure the voltage drop caused by the soil to a designated point and then use ohm s law to. Ground testing is the verification that resistance between your grounding system and earth meets the specifications of the national electrical code nec and other pertinent guidelines. On modern electrical systems rcd s and rcbo s are regularly fitted these devices react to electricity missing from the circuit or installation such as when a person is receiving an electric shock as the electricity passes through his body to the ground earth. Prior to about 15 years ago the basic methodology for ground testing remained fundamentally unchanged since it was originally devised in the early 20th century.

Ground for electrical products and systems. When installing a ground rod you need to make sure that electricity will easily flow through it into the earth. This ensures that the resistance to ground does not increase over time.
