    Complete Ground System Testing

    When performing complete grounding system testing that is testing it at each location, is it a requirement not to connect the phase conductors?

    Can you elaborate a bit on exactly what you are trying to do? How is the testing done? Is this testing earthing, such as grounding electrode resistance or equipment bonding?

      There are three basic ground tests, a 4-Point test performed to aid in designing a ground system for a site, a 3-point test is utilized to measure the resistance of an electrode to Earth (the electrode is isolated from the electrical distribution system) and a 2-point test (continuity test) is utilized to verify resistance to a known ground. All three tests require specialized test equipment. In the first test there is no existing electrical system or is utilized to design a new ground electrode system, in the last two tests whether the phase conductors are terminated or not is not important BUT in the 3-point test you have isolated (disconnected) the Grounding Electrode so a system outage would be prudent, in a 2point test you are often going into energized distribution equipment and as always be careful, safety first as working around energized systems requires special precautions.
