Electric utilities place high priorities on the design of effective grounding system to achieve the level of electric safety demanded by the society. The National Electrical Safety Code (NESC) and the National Electric Code (NEC) have specific regulations to achieve the safety of the public from electric shocks.
Stray voltage is one of the most annoying problems associated with customers’ services. It is hard to predict and detect and the solution can be illusive. Stray voltage can cause substantial losses in farms and can lead to unsafe conditions for the public. This course covers the foundations of grounding and stray voltage analysis. It also identifies sources of stray voltages and methods to alleviate the problems. Applicable standards and codes are discussed and engineering analyses of the problems are given.
Several real-world cases are presented, studied and analyzed in this course. In addition, some of the tools used to analyze the hazards and to test the proposed solutions of the stray voltage problems are presented.
