The DET2/3 is a robust and compact automatic earth (ground) test instrument designed to measure earth electrode resistance and soil resistivity. The DET includes the option for remote control. For use on large or more complex earth systems, which include communications earth systems and difficult test environments, it can be used to test in accordance with BS 7430 (earthing / grounding), BS-EN-62305 (Lightning Protection), BS-EN-50122-1 (Railway Applications), and IEEE Standard 81.
Test frequency, test current and filtering can be quickly and easily adjusted so that adverse conditions, which can influence the test, can be overcome, and a wide band of test current frequencies, with a resolution of 0.5 Hz, can be used to eliminate errors caused by noise in the earth.
The GTS-300 is a two-piece test set designed to ensure the integrity of grounding systems and to test personal safety grounds. The high-current method of testing ground grid continuity and connections is a reliable, accurate method of detecting faults in the ground system.
The DET4 contractor series includes -
The DET4TD, DET4TC and DET4TCR replace the DET5/4R and DET5/4D.
