Megger DET3 Series 3-Terminal Digital Ground Tester
Product Description
The DET3TD is for basic ground testing while the DET3TC includes a current measuring function for ART (Attached Rod Technique) testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection (as explained further in this document).
By using the optional ICLAMP with the DET3TC, the user can augment the traditional fall-of-potential measurement method with ART (Attached Rod Technique), which allows electrode testing without disconnection and also leakage current measurements down to 0.5 mA.
