IEEE 953 - GROUNDING OF INDUSTRIAL POWER SYSTEMS Organization: IEEE
Date: 1956-10-01
Description: Looking at the problem from an overall standpoint, the grounding of the system would in most cases be done by making a metallic connection direct or through impedance between transformer or generator neutrals and the building grounding system which is described in Chapter 11. The grounding system described in Chapter II in turn is connected to earth through the system of ground rods and water pipes descried in Chapter IV.

IEEE 81.2 - GUIDE FOR MEASUREMENT OF IMPEDANCE AND SAFETY CHARACTERISTICS OF LARGE, EXTENDED OR INTERCONNECTED GROUNDING SYSTEMS Organization: IEEE
Date: 1991-01-01
Description: ScopeTest methods and instrumentation techniques used to measure the ac characteristics of large grounding systems include the following topics: 1) Measurement safety 2) Earth-return mutual errors 3) Low-current measurements 4) Power-system staged faults 5) Communication and control cable transfer impedance 6) Current distribution (current splits) in the grounding system 7) Step, touch, mesh, and profile measurements 8) The foot-equivalent electrode earth resistance 9) Instrumentation characteristics and limitations Grounding electrodes consisting of a single ground rod, arrays of ground rods, tower footings, and many grids (if no external grounding is connected) can be measured, interference voltages permitting, with methods outlined in IEEE Std 81-1983 [2] 1 .
