The ETCR5500 series ground resistance detection sensor breaks through the traditional detection method and adopts clamp-type non-contact measurement. It is widely used in the ground resistance measurement of electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment. Magnetic shielding technology and CT technology can ensure high precision, high reliability, and high stability for year-round uninterrupted testing.
The ETCR5500 series is divided into a clamp-shaped open-loop structure and a closed-loop structure, as well as a long jaw and a round jaw. The long jaw is particularly suitable for flat steel grounding occasions and can meet the detection of various grounding systems. For the grounding system that forms a loop, there is no need to disconnect the grounding down conductor, and no auxiliary electrode is needed, which is safe and time-saving.
