The grounding system described in Chapter II in turn is connected to earth through the system of ground rods and water pipes described in Chapter IV.<br />\n
          The protective systems discussed for static and lightning protection in Chapter III would likewise be connected to the ground rods and water pipe system as outlined in Chapter IV.<br />\n
          \t\t\t\t<br />\n
          The question of whether or not to ground a power system is one which mu9t be faced sometime by most engineers charged with planning industrial distribution.<br />\n
          A decision in favor of a grounded system leads then to the question of how to ground.<br />\n
          It is the intent of this chapter to assist the planning engineer to answer these and other more detailed questions on the subject, by presenting basic reasons for grounding or not grounding and by reviewing general practices and methods of system grounding.

The advantages and disadvantages of grounded vs. ungrounded systems are discussed. Information is given on how to ground the system, where the system should be grounded, and how to select equipment for the ground of the neutral circuits. Connecting the frames and enclosures of electric apparatus, such as motors, switchgear, transformers, buses, cables, conduits, building frames, and portable equipment, to a ground system is addressed. The fundamentals of making the interconnection of a ground conductor system between electric equipment and the ground rods, water pipes, etc., are outlined. The problems of static electricity— how it is generated, what processes may produce it, how it is measured, and what should be done to prevent its generation or to drain the static charges to earth to prevent sparking—are treated. Methods of protecting structures against the effects of lightning are also covered. Obtaining a low-resistance connection to earth, use of ground rods, connections to water pipes, etc., are discussed. A separate chapter on electronic equipment is included.<br />\n

          The problems of system grounding, that is, connection to ground of neutral, of the corner of the delta, or of the midtap of one phase, are covered. The advantages and disadvantages of grounded versus ungrounded systems are discussed. Information is given on how to ground the system, where the system should be grounded, and how to select equipment for the grounding of the neutral circuits. Connecting the frames and enclosures of electric apparatus, such as motors, switchgear, transformers, buses, cables conduits, building frames, and portable equipment, to a ground system is addressed. The fundamentals of making the interconnection or ground-conductor system between electric equipment and the ground rods, water pipes, etc. are outlined. The problems of static electricity—how it is generated, what processes may produce it, how it is measured, and what should be done to prevent its generation or to drain the static charges to earth to prevent sparking—are treated. Methods of protecting structures against the effects of lightning are also covered. Obtaining a low-resistance connection to the earth, use of ground rods, connections to water pipes, etc. is discussed. A separate chapter on sensitive electronic equipment is included.<br />\n

          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 an impedance between transformer or generator neutrals and the building grounding system which is described in Chapter II. The grounding system described in Chapter II in turn is connected to earth through the system of ground rods and water pipes described in Chapter IV.<br />\n
          The protective systems discussed for static and lightning protection in Chapter III would likewise be connected to the ground rods and water pipe system as outlined in Chapter IV.<br />\n
          \t\t\t\t<br />\n
          The question of whether or not to ground a power system is one which mu9t be faced sometime by most engineers charged with planning industrial distribution.<br />\n
          A decision in favor of a grounded system leads then to the question of how to ground.<br />\n
          It is the intent of this chapter to assist the planning engineer to answer these and other more detailed questions on the subject, by presenting basic reasons for grounding or not grounding and by reviewing general practices and methods of system grounding.
