This part of GB/T 17949.1-2000 focuses on the routine measurement of grounding systems. It provides guidance for soil resistivity, grounding Impedance and ground potential measurement, and details the commonly used Measuring methods, such as the quadrupole method for measuring soil resistivity. Clarify the required measuring instruments and accuracy requirements, and standardize the preparation work before measurement, including the selection of measuring points and electrode arrangement. For different measurement items, describe the specific operation process and Data processing method. By following this standard, the key parameters of the grounding system can be accurately obtained, providing a reliable basis for the design, construction and maintenance of grounding engineering in the power, communication and other industries, and ensuring the safe and stable operation of the system.
