    In the electrical point of view and as a safety measure, metallic fence shall be separately earthed unless they come within m of any equipment or structure above the surface of the ground, which is connected to the main earthing system. If the separation of m cannot be obtained the fence shall be bonded to the earthing system. Here is how compound fences connecting to the earthing system. point of reference; for most systems that is the earth. Grounding=s main purpose is to provide a common point of reference between various sources of electrical energy, i.e. Different power systems - Public Utilities, on-site generation, battery systems Different voltage systems - .

Introduction to Substation Earthing Grid. In high and medium voltage Air Insulated Substations (AIS) the electromagnetic field, which causes are the static charges of bare cable and conductors and by the atmospheric conditions (surges), induce voltages at no-live parts of the installation that create potential differences between metallic parts and ground and also between different points.

IC () Guide for the Construction of Driven-rod Ground Beds IC () Guide to Substation Grounding and Bonding for Mine Power Systems. lation of grounding systems requires knowledge of soil characteristics, grounding conductor materials and compositions and grounding connections and terminations.

A complete guide to proper grounding is often part of national and international standards. For example, IEEE Guide for Safety in AC Substation Grounding, is a. System grounding has been used since electrical power systems began.

However, many companies and industrial plants have used system grounding methods differently. The problem of whether a system neutral should be grounded, and how it should be grounded, has many times been misunderstood completely. Therefore, grounding of many systems has. This method of measurement is detailed in the Bureau of Mines Publications ICGuide to Substation Grounding and Bonding for Mine Power Systems.

The fall of potential method is also covered in many other publications that are readily available and is part of the instructions contained with earth resistance measurement equipment.

n Power Generating Systems n Grounding n This metal fence grounding requirement may be accomplished by bonding the fence to the substation grounding grid or to a separate underground NESC.

20 Various fence grounding practices are: n Fence is within the ground grid area and is connected to the substation ground grid. Additional Physical Format: Print version: Cooley, Wils L. Guide to substation grounding and bonding for mine power systems. [Washington, D.C.]: U.S.

Dept. of the. Although electric utility companies have been active in grounding and bonding within substations, the mining engineer or mine electrical engineer is not involved to the extent that he can be fully up-to-date on the most effective practices for substation construction.

The coal mine power system is grounded in a fundamentally different way from. Once a reliable system ground has been established that connects all the metallic frames of electrical equipment together, then the grounding system must be placed at some reference potential.

Improper frame grounding is the cause of many electrical accidents in metal/nonmetal mines. transmission systems and electric power distribution design. The main purpose of power system substation grounding grids is to maintain reliable operation and provide protection for personnel and apparatus during fault conditions.

Grounding system allows controller harmonics and drain to earth the fault currents. With today’s advances in. NASA Images Solar System Collection Ames Research Center.

Bonding: Electrical power systems, such as the secondary winding of a transformer are grounded. Consistent adherence to IEEE Standard would save billions of dollars annually over today's common practices. What makes this standard so powerful?To many of us, properly designing and installing a commercial or industrial grounding system is often a confusing process.

Fortunately, IEEE Standard provides all the information you need to clear up confusion and develop a good grounding design. Substation Grounding Training - This Hour live online instructor-led course will discuss how to maintain, test, and inspect a proper grounding system for high voltage transmission and distribution systems and especially the electrical power substation.
