Power Testing and Grounding of Electronic Systems

Starting from the basics of a power distribution system the author explained the mechanism of how grounding noise currents arise in a facility transformer. This is followed by computer simulation of short circuit or fault currents required in sizing the interrupting capacity of a circuit breaker. <br> Chapter 3 closely examines propagation constant and characteristic impedance of a transmission line. The model of a transmission line can explain most of the electrical or electronics problems. Some of these problems include redundancy in power systems and grounding noise voltage. <br> Often an engineer needs to find the cause of a failure in a system. He must have at his disposal a systematic method of testing to find the most probable cause of failure. This book recommends the boundary approach in finding such a cause. Testing may involve characterizing a device or a signal. An example of how an unknown device may be characterized is shown in this book. <br> In this book a grounding noise voltage is treated as a signal. It is perhaps the most common cause of failures in electronic systems. To illustrate an example of how a signal may be characterized and address grounding itself Chapter 7 shows experiments on how a grounding noise voltage may be minimized. Finally Chapter 8 is a recommended approach in designing a grounding system.
