The earth tester / earth resistance meter is a versatile ohmmeter. With this grounding meter a variety of resistance measurements can be performed. Thus, with the grounding meter, the possibility exists to perform a normal resistance measurement of 2- or 4-pole application. It is also possible to determine the resistance of the soil with the grounding meter. For the measurement of earth resistance corresponding earth spikes are included in the scope of supply. These ground spikes can easily be connected to the grounding device via the supplied separate 20 meter / 66 ft cable.

Another important measuring function is the measurement of the resistance of, for example, lightning conductors. This measurement is used to control the lightning conductors on, for example, schools or university buildings and is essential to derive a possible lightning strike into the ground. This earth tester / earth resistance meter can thus be used to determine whether the lightning rod is properly connected to the ground and whether it has the right resistance value to discharge a lightning bolt into the ground.

To ensure a perfect measurement, the earth tester / earth resistance meter has a measuring terminal detection. After the operator has set the grounding meter to the desired measurement function, the terminals to be used light up. If an incorrect connection has been selected by the operator, the grounding meter signals the operator both acoustically and visually. At the same time, the measurement by the grounding meter is refused until the test setup has been properly connected. This massively limits faulty measurements by the intelligent grounding meter. Also, the grounding device has a memory. This allows the measurement data from the grounding meter to be transferred to a PC and evaluated after a measurement.

What are the methods of measuring Earth Resistance?

There are primarily three methods to measure earth resistance: the fall-of-potential method, the 62% method, and the star-delta method.

1. Fall-of-Potential Method: This is the most common method. It uses three electrodes: the earth electrode under test (EUT), a potential electrode (P), and a current electrode (C). The EUT and P are connected to the earth tester meter. The meter injects a known current through the EUT and C and measures the resulting voltage drop between EUT and P. The earth resistance is then calculated using Ohm's Law.

2. 62% Method: This is a variation of the fall-of-potential method. It involves moving the potential electrode to a point where it is 62% of the distance from the EUT to the outer electrode (C). At this point, the resistance reading is at its minimum and most accurate.

3. Star-Delta Method: This method uses four electrodes instead of three. While it's more complex, it provides more accurate measurement, especially in areas where the ground composition is uneven.

Each method has its advantages and is used in different situations. The choice depends on the specific requirements of the measurement task and the characteristics of the site.

A qualified engineer should be consulted to determine which method is most suitable for the situation at hand.

ADK Instruments offers a wide range of earth tester meters that are capable of accurately measuring earth resistance using all three methods.

What principle does earth tester work?

The earth tester meter operates on the principle of Ohm's law. This fundamental law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points. In practical terms, an earth tester meter applies a known voltage to the earth electrode under test and measures the resulting current. By doing this, the device can accurately calculate the resistance of the earth electrode. The measurement provided by the earth tester meter is crucial in ensuring electrical systems are properly grounded. This grounding helps to safeguard both equipment and personnel, preventing electrical faults and reducing the risk of electrical shock.

What is the voltage of the earth tester?

The voltage applied by an earth tester meter can vary based on the specific model and manufacturer. However, a common operating voltage for many earth tester meters is in the range of 25V to 50V. It's crucial to note that the appliance measures the resistance of the earth electrode, which is then used to calculate the earth's resistance. The exact voltage is typically selectable on the instrument, allowing the user to choose the most suitable voltage level for the conditions. This flexibility makes the earth tester meter a versatile tool for assessing the safety and efficacy of grounding systems in various environments.

Are Earth Tester and Megger the same?

While both the Earth Tester and Megger serve important roles in electrical safety, they are not the same instrument. An Earth Tester, as the name suggests, is specifically designed to measure earth electrode resistance and soil resistivity, ensuring the effectiveness of grounding systems according to Ohm's law. On the other hand, a Megger, or insulation tester, is used to evaluate the insulation resistance of electrical wiring and equipment. This is crucial in preventing unexpected power failure or electrical shock due to insulation breakdown. Therefore, while both tools are integral to maintaining the safety and reliability of electrical systems, they perform different functions and cannot be used interchangeably.

What are P and C in the earth tester?

In an earth tester meter, the terms 'P' and 'C' refer to the potential (P) and current (C) terminals or probes employed in the process of earth resistance measurement. The 'P' probe is usually placed along the line between the earth electrode under test and the 'C' probe, which is positioned at a distance from the earth electrode. The arrangement facilitates the creation of a known voltage division from which the earth's resistance can be calculated. By utilizing these probes, the earth tester meter accurately measures the resistance of the earth electrode, ensuring the safety and efficacy of the grounding system.
