Difficulty: 0

Hi! Our topic on this episode is about pole ground testing. This is a sequel video after

the pole grounding installation activity. After installing the pole grounding, we need

to test whether the resistance value of the grounding rod meets the standards according

to Globe telecom Philippines standard. The resistance value of the grounding should

be less than 25 ohms. These are the tools needed for this activity: ground ohmmeter

or tester, conductor rods, wrench and hammer. Locate suitable test rods location. It should

be 2 to 5 meters away from the grounding rod to be tested. Stab the first test rod to the

ground with the aid of hammer. The test rod should reach 4 inches depth below the ground.

Do the same for the second test rod. Remove messenger wire from bonding to the grounding

rod. Use wrench to loosen the nuts. Attach the clamp of the first test probe to the first

test rod. Insert test probes to the test equipment on to its corresponding port.

On this case the yellow test probe is the first rod. Green test probe is for the grounding

rod. Attach the clamp of the second test probe to the second test rod. On this case the test

probe color is red. Insert test probe on its appropriate port.

Attach the clamp of the green test probe to the grounding rod. After setting the test

probes, operate the resistance meter or ohmmeter. Set resistance range to 200 ohms value.

Press start to initiate testing. As you can see, the resistance reading is 10.2 ohms.

This reading pass the prescribed resistance value. Take note the test results and mark

it as your first trial. One factor that affects the resistance value

is the existing soil condition. Conduct another test by moving the test rods position on to

other location. Run the same test and note the value of the resistance. Mark the second

test as the second trial. As you may see the value of the resistance change to 8.8 ohms

after the test. Put back the messenger wire and grounding clamp from its bonding.

There is another type of ground resistance meter that doesn't require test rods which

is the earth resistance clamp meter. This testing equipment is better than the other

one showed earlier. This testing equipment doesnt need the

messenger wire to be detached from its bonding to the grounding rod.

On the test sheet form, write the pole tag and address location from where the grounding

has been tested. If the resistance test results fails or exceeds

25 ohms reading, there are two possible solutions we can do to lower down the resistance reading.

First option is to move the existing grounding rod position to a location where in damp soil

is present and rerun a longer messenger wire to reach the new rod position. Second solution

is to install another grounding at least one meter away from the existing rod. The two

rods will be connected in parallel with each other by a single messenger wire.

I hope I was able to give knowledge with you regarding this outside plant related activity.

Thank you for watching.
