MEGGER Earth Ground Resistance Testers
MEGGER Earth Ground Resistance Testers Pioneered Ground Resistance Testing
The MEGGER company, established in the late 1800s, has been designing and making test and measurement instruments that perform electrical measurements for preventative maintenance and electrical troubleshooting. The MEGGER Earth Ground Resistance Testers were pioneered and introduced in the early to mid 1900’s and are the technology and innovative leaders of today. The MEGGER Earth Ground Resistance Testers are designed to conveniently measure the electrical conductive of the Earth. Megger offers over a dozen technical choices and solutions to satisfy your particular application.
MEGGER Earth Ground Resistance Testers Measures Earth’s Conductivity
The Earth’s electrical conductivity properties are put to practical use in every day applications in industrial plants and in the utility industries worldwide. Actually, the earth is a relatively poor conductor of electricity compared to normal metallic conductors like copper and aluminum. However, if the area of a path for current flow is large enough, resistance can be quite low and the earth can be a good conductor. It is the earth’s abundance and availability that make it an indispensable asset type component of a properly functioning electrical system. Determining effectiveness of “ground” grids and connections that are used with electrical systems to protect personnel and equipment is a fundamental application. Measurements of earth resistivity are most useful for finding the best location and depth for low resistance electrodes for neutral connections.
The Megger DET family of test instruments offers a unique solution to the measurement of earth or ground electrode (rod) resistance and soil resistivity. The family has three digital variants, which support 2, 3 and 4 point (DET4TD only) testing, and one analogue version that makes provision for 2 and 3 point measurements.
The DET3TC can use an optional current clamp (ICLAMP) to measure electrode (rod) resistance without disconnection, leaving the installation earthing system intact (Attached Rod Technique, ART). The DET3TC in conjunction with the current clamp can also measure conductor current.
The DET Series variants have the following features:
Feature | DET3TA | DET3TC | DET3TD | DET4TD |
Automatic C spike check | ~ | YES | YES | YES |
Automatic P spike check | ~ | YES | YES | YES |
Manual P spike check | YES | |||

4-wire test | ~ | ~ | ~ | YES |
No disconnect testing (ART) | ~ | YES | ~ | ~ |
Voltmeter (ground noise voltage measurement) | YES | YES | YES | YES |
Megger DET2/2
|
The Megger DET2/2 digital ground resistance meter measures earth electrode resistance and soil resistivity to increase the safety and performance of electrical systems. The unit measures digitally and has manually-selected test current, test frequency, and filtering so that it can be used in noisy environments. The meter uses the four-terminal method to eliminate the circuit current resistance for more accurate measurements. Megger_DET2-2 Datasheet | |
