The Ultimate Earthing Solution.
ET 46D
The ET 46D Earth Tester by TAURUS is meticulously designed for accurate and efficient measurement of earth resistivity and earth resistance in power stations and substations. Employing advanced techniques such as the 4-point Wenner method for resistivity and the 3-point fall of potential method for resistance, the ET 46D ensures superior performance in diverse and challenging environments.
In modern power stations and substations, all electrical equipment is grounded to a station earth mat through earth electrodes. These electrodes are critical for maintaining safety, as they effectively discharge overvoltages or fault currents caused by lightning strikes or system faults. Regular monitoring of earth resistance is essential, and the ET 46D provides an ideal solution for such critical applications.
The ET 46D is a portable and robust device, offering an extensive measurement range of 0 to 20K ohms. Its advanced design ensures exceptional immunity to electromagnetic interference, power frequency noise, and harmonics. With unparalleled noise suppression and stable readings, the ET 46D delivers precise and repeatable results, even in high-noise environments like power stations.
Choose the ET 46D for unmatched accuracy, reliability, and ease of use. This innovative earth tester is an indispensable tool for engineers and technicians tasked with ensuring electrical safety and system integrity in substations and power stations.
