Introduction
The Bureau of Land Management (BLM) communication network is vital to its operational mission to ensure employee safety, public safety, and resource protection. The BLM has identified a need to bring its communications sites to meet or exceed Motorola R56 standards. The Radio Infrastructure Compliance, Assessment, Safety, Health, and Environment (RI CASHE) audit program uses the Motorola Standards and Guidelines for Communication Sites as the minimum requirements for radio facility maintenance and design of the ground ring. RI-CASHE assessments have been performed for some BLM facilities to assist with correcting the deficiencies.
Objective
BLM CA needs to ensure that its operational mission is meet by installing a prefabricated communication site at Gun Site Peak in California per bureau directives.

| B. | The following forms are to be used for recording test results of the grounding electrode system. |
| 1. | Attachment 2B – Fall-of-Potential Ground Resistance Field Report |
| 2. | Attachment 1A – Clamp-On Ground Resistance Field Report |
Grounding Electrode System Resistance Testing
A. Fall-of-Potential Testing – Small Grounding systems – 62% Rule (1 to 6 Grounding Electrodes)
1. The fall-of-potential method is often referred to as the "three-point method". Utilizing a ground resistance meter (digital is preferred), two auxiliary electrodes are driven into the soil at predetermined distances (up to 10 times the cross-sectional dimension of the grounding system), per the testing specifications, in a straight line from the ground being tested.
2. During a normal test of ground rod(s) the meter supplies a constant current between the ground rod(s) under test and the most remote auxiliary electrode. A series of measurements of the voltage drops between the ground rod(s) under test and the remote electrode are made by moving the intermediate electrode in steps away from the ground rod under test. The goal is to reach the actual rod’s resistance, and this is most often reached at the 62% distance point.
| B. | Fall-of-Potential Testing – Large Grounding systems (6 or More Grounding Electrodes) The usual method of measurement that works very well has one disadvantage; namely, that it is generally necessary to place the auxiliary current probe at a considerable distance from the earth-electrode system. In some cases, this distance can be as much as 3000 ft., and this is not always convenient or possible. |
| 1. | Intersecting Curves: An alternative method, in which such long leads are not necessary, has been devised called Intersecting Curves. The basic principle is to obtain earth resistance curves for several current electrode spacing and, by assuming several successive positions for the electrical center of the system, to produce intersection curves which will give the earth resistance and the position of the electrical center. |
| a. | Some rather difficult problems are encountered when the resistance of an earth-electrode system, consisting of a few grounding electrodes, ground rods, plates, etc., all connected in parallel and spread over a large area, is to be measured. |
| 2. | Slope Method is a variation of the Intersecting Curves method. This method does not require long lengths of test leads. The section labeled Slope Method provides a detailed explanation of the Slope Method, including relevant tables. |
Fall-of-Potential Method
| A. | The fall-of-potential method is often referred to as the "three-point method". Utilizing a ground resistance meter (digital is preferred), two auxiliary electrodes are driven into the soil at predetermined distances, per the testing specifications, in a straight line from the ground being tested. |
| 1. | Grounding mats and grounding systems, other than rods, often require a modified test method. During a normal test of ground rod(s) the meter supplies a constant current between the ground rod(s) under test and the most remote auxiliary electrode. |
| 2. | A series of measurements of the voltage drops between the ground rod(s) under test and the remote test electrode (Z – Probe – Current) are made by moving the Y – Probe (Potential) in steps away from the ground rod under test. |
| 3. | The goal is to reach the actual rod’s resistance, and this is most often reached at the 62% distance point. |
| 4. | The Z – Probe (current) must be placed a minimum of 5 times the distance of the length of the ground rod being tested. It is preferable the most remote electrode be placed a distance equal to 10 times the length of the rod under test. |
| a. | During the test, the neutral for the commercial electrical service must not be connected to the ground rod. The neutral-to-ground bond must be disconnected, as the current flow on the neutral will invalidate the test results and not all the test instruments provide an accurate reading. |
| 5. | When graphed, the series of measurements of the voltage drops between the ground rod under test and the remote electrode when graphed will provide a chart that will look like the one below. The band of error will be those areas outside the flat part of the graph. |
Slope Method:
| A. | The Slope Method can be used effectively because it does not require the user to find the “flat” portion of the curve or to know the electrical center as a point from which to measure. Readings are taken at 20 percent, 40 percent, and 60 percent of the current probe distance and fit into a mathematical model of the resistance characteristic. |
| B. | It is the purpose of this method to reduce that distance to the current probe, and this appears to have been achieved, but there are some additional points to be noted. From the work, which has been done on the method, there are certain limits to the distance to the current probe. |
| 1. | To comply, if the grounding system is in the form of a square, the minimum distance to the current probe should not be less than the side of the square. On the other hand, the maximum distance should not be too great. If it is, the resulting curve is very flat, and the intersection point becomes rather indefinite. |
| 2. | For a square grounding system, this maximum distance should not exceed twice the side of the square. For other shapes of earth-electrode systems, it is necessary to judge suitable minimum and maximum values for the distance to the current probe. |
| 3. | Suppose that all measurements are made from an arbitrary starting point O, the distance Z to the current probe and the variable distance Y to the potential probe being measured from this point. Then a curve such as ABC (See Figure Below), giving the measured resistance against the value of Z, can be obtained. |
| 4. | Now suppose the electrical center of the earth-electrode system is actually at D, distance X from O. Then the true distance from the center to the current probe is Z + X, and the true resistance is obtained when the potential probe is at a distance 0.618 (Z + X) from D. This means that the value of Y, measured from O, is 0.618 (Z + X) - X. |
| 5. | If X is now given a number of values, the corresponding values of P can be calculated, and the resistance read off the curve. These resistances can be plotted against the values of X in another curve. When this process is repeated for a different value of C, and another curve of resistance against X obtained, the two curves should cross at the required resistance. The process can be repeated for a third value of C as a check. These curves are called intersection curves. It has been assumed that D, O and C are in the same straight line. |

Table 4.6 A – Example of Calculations
| 6. | The other challenges faced in testing large ground systems relate to the capabilities of the test instrument. Improved technology has made it possible for instruments to be designed that address problems created by the characteristics and conditions found in and around large ground systems. |
| 7. | For the Slope Method to provide meaningful results, accurate measurement of the variations at different points is critical. Since large ground systems typically have resistance values of less than 0.5 Ω, the differences can be quite small. An instrument with 1 mΩ measurement resolution can indicate the small differences between low readings. |
| 8. | Noise is a major problem in testing large ground systems and must be addressed to ensure accurate results. To be effective, the test instrument must be designed to overcome the effects of significant noise in the test environment. Among the technical capabilities that can help offset the noise problem are: |
| a. | A variable test frequency (rather than a single, fixed test frequency) which can help remove any stray noise that could affect the reading. |
| b. | A high peak-to-peak interference suppression level. |
| c. | A sophisticated filter system to reject more noise. |
| d. | Various current settings to improve the signal-to-noise ratio when necessary. |
