Sets forth the steps needed to protect criticaltelecommunications circuits from power faults and lightning in highvoltage environments
The need to protect telecommunications circuits from powerfaults and lightning has never been greater: when power outages orsystem disturbances occur, reliable telecommunications areessential. With this book as their guide, readers will know whatthey need to do (and not do) to protect critical telecommunicationscircuits and equipment located in high voltage environments such aselectrical power plants, substations, and power towers. Moreover,the book explains how to get the job done safely, detailing theproper implementation of safety procedures and the use ofprotective equipment to eliminate or minimize risk.
Setting the foundation, the book begins with an overview of theproblem, key issues, industry standards, and safety concerns. Next,it covers:
* Definitions and fundamentals of electric power systems, withregard to HVPT applications
* Causes, boundary conditions, and calculations of groundpotential rise
* Critical telecommunications circuits that must be protected inhigh voltage environments
* Protection schemes and equipment to resolve ground potentialrise problems
* Effective installation and testing of high voltage interfaceequipment
* Personal safety for telecommunications personnel working withequipment in high voltage environments
Throughout the book, the author refers to accepted industrystandards and best practices. Written by one of the most respectedprofessional trainers in the telecommunications industry, HighVoltage Protection for Telecommunications can be used forprofessional training courses or self-study. It will enable readersto protect critical data and voice communications circuits fromhigh voltage events and protect themselves during equipmentinstallation and maintenance.
