This is a discussion of the basic principles behind grounding systems and how grounding is related to safety and the effective operation of circuit protection devices such as fuses and circuit breakers. The discussion moves quickly from a basic study of grounding to simple examples of a single building installation and onto

Electrical earthing / grounding is one of the most important aspects of any electrical installation. Earthing or Grounding is a technique which is as old as the use of electrical power on a commercial scale. The practice came in to existence in the early days of electricity when the systems in use were all ungrounded and that

techniques summarised in the following sections. 1.3.2 SOIL RESISTIVITY TESTING PROCEDURE GUIDELINES. The purpose of resistivity testing is to obtain a set of measurements which may be interpreted to yield an equivalent model for the electrical performance of the earth, as seen by the particular earthing system.
Introduction. Nothing is quite so common or abundantly available throughout the world as the earth's soil. We are more apt to think of earth as something to be tilled for planting or to be excavated for a building foundation. Yet, it also has an electrical property -- conductivity (or low resistance) -- that is put to practical use
