Megger has launched an earth/ground resistance tester named DET2/3 with optional test lead reels to reduce time and frustration for the operator. The high-performance ground tester replaces DET2/2 that has been widely used in the industry for 25 years.
DET2/3 features a graphic display for better data analysis, error detection capabilities, as well as a wide range of test frequencies to ensure noise protection. The company says DET2/3 offers improved accuracy and stability. DET 2/3 has a test frequency range of 10 Hz to 200 Hz in steps of 0.5 Hz, with an automatic frequency selection feature that allows users to ensure tests are carried out at the frequency with the lowest noise level.
The new model of the ground tester has a large internal memory that allows quick calculation of resistivity and storage of more than a day’s worth of test results. The results can be downloaded to a USB flash drive or directly to a PC running PowerDB software.
DET2/3 meets IEEE Standard 81 and is suitable for testing grounding and lightning protection. It has an IP54 rating during use for real-world conditions as well as IP65 protection (with the lid closed). Supporting two-, three- and four-pole ground resistance measurements, this tester is an excellent diagnostic tool for anyone performing ground testing, according to the company.
Megger is a leading manufacturer and supplier of test and measurement equipment used in the electric power, building wiring, and telecommunication industries.
