Critical telecommunications circuits are often located in HV environments such as electric utility power plants, substations, cell sites on power towers, and standalone telecommunications facilities such as 911 call centers and mountaintop telecommunications sites.

The need for highly reliable telecommunications circuits during power faults and lightning strikes when controlling our nation’s electric power grids, communicating via wireless phones, and conversing with public safety support individuals at 911 call centers has never been higher.


The utilization of the information provided in this High Voltage Protection for Telecommunications book should help provide higher reliable telecommunications circuits and improve the safety of personnel working in HV environments.

Several industry standards and best practices are referenced throughout this High Voltage Protection for Telecommunications book.

These standards and practices are based on power and telecommunications company experience, field testing, workgroup committees, equipment manufacturers’ support, and the advice of construction contractors and industry experts/consultants. 

This High Voltage Protection for Telecommunications book is very comprehensive in that it combines several detailed references into a practical general-purpose applications reference guide.

There are a power and telecommunications industry concern that a high percentage of people knowledgeable in this subject area have either retired or are approaching retirement, and these industries are losing valuable expertise for proper application solutions.

This High Voltage Protection for Telecommunications book is intended for individuals new to this subject area who want a working knowledge of the concepts, design techniques, and industry’s best practices.

Likewise, subject area professionals require knowledge of the dos and don’ts regarding the special electrical phenomena that affect telecommunications circuits that are required to be reliable and safe to maintain.

The target audience is managers, engineers, planners, and technicians involved in protecting critical telecommunications circuits from the adverse effects of electric power faults and lightning strikes.

Personnel in public safety, natural gas, water, public utilities, and others involved in assuring that critical telecommunications circuits are reliable under lightning conditions should find benefit from reading this High Voltage Protection for Telecommunications book.

What is not covered in this High Voltage Protection for Telecommunications book are the details surrounding each type of telecommunications circuit such as digital subscriber line (DSL), high-speed DSL, T1, plain old telephone service, the difference between two-wire and four-wire circuits, and so on.

This information is readily available on the Internet and from other resources such as the following:

  • Subscriber Loop Signaling and Transmission Handbook–– Analog by Whitman D. Reeve
  • Subscriber Loop Signaling and Transmission Handbook–– Digital by Whitman D. Reeve

Also not included in this book are the vendor-specific details of their proprietary HV isolation equipment and details contained in the referenced industry standards.

The focus here is to explain how such critical circuits are protected from lightning strikes and power faults, plus the safe handling of such circuits should a power fault or lightning strike occurs at the time of construction or maintenance.

This High Voltage Protection for Telecommunications book provides a helpful reference to implement concepts correctly and to recognize situations to avoid.

The reader should also be aware that sophisticated computer programs and consulting services are readily available for guidance with unique circumstances that may not be covered in this High Voltage Protection for Telecommunications book.

This High Voltage Protection for Telecommunications book does provide the knowledge and background necessary to work closely with consultants or to understand the principles of sophisticated computer programs.

Chapter Summaries

A brief overview of each chapter is presented below to summarize the flow of technical information and to help identify what and where specific topics are covered in this High Voltage Protection for Telecommunications book Chapter 1 presents an overview of high voltage protection for telecommunications (HVPT).

The High Voltage Protection for Telecommunications book starts out with a brief yet informative discussion of the impending problems that can occur when critical telecommunications circuits exist in HV environments.

The purpose of this chapter is to quickly familiarize the reader with the important issues, industry-standard solutions, and safety aspects affecting telecommunications reliability during lightning and power fault situations.

Chapter 2 discusses the fundamentals of electric power systems to help readers who are unfamiliar with HV equipment become better acquainted with HVPT applications.

A basic model of the overall electric power system is presented to establish a fundamental understanding of how power systems work and the electrical phenomena that can interrupt critical telecommunications circuits and, if the system is not properly protected, cause equipment damage and injury to personnel.

This chapter explains how substation ground grids, protective relaying, fault clearing devices, lightning arresters, and telecommunications equipment are used to clear power faults to minimize equipment damage and maximize electric service reliability.

Chapter 3 elaborates on the concepts of ground potential rise (GPR) and zone of influence (ZOI).

These two concepts are fundamental to this subject area, and proper protection design, installation, and maintenance depend on a solid understanding of these concepts.

The definitions, causes, boundary conditions, and calculations of GPR and ZOI are discussed in this chapter. The critical telecommunications circuits found in HV environments are discussed in Chapter 4.

The various classes and types of critical telecommunications circuits used by power and telecommunications companies and public service providers where HV protection is necessary are also discussed.

Examples of situations which require HV protection are the critical electric power systems control centers and associated protective relaying applications, telephone companies that are using telecommunications circuits involving wireless radio equipment mounted on HV electric power towers, and 911 call centers, which have their respective requirements for critical circuit reliability.

The standard service performance objectives (SPOs) and standard levels of protection are discussed in this chapter.

Chapter 5 presents discussions about the actual HV protection equipment used in these critical circuit situations. (High Voltage Protection for Telecommunications)

The concepts behind modern telecommunications protection schemes and equipment used to resolve GPR problems are also discussed, as well as references to industry standards and typical manufacture equipment offerings.

Chapter 6 discusses proper installation and testing procedures of high voltage interface (HVI) equipment. (High Voltage Protection for Telecommunications)

The design and installation objectives, both theoretical and physical, for reliable HV isolation are the focus points of this chapter.

Proper design and installation are paramount; however, attention is given to the dos, don’ts, and common installation deficiencies. (High Voltage Protection for Telecommunications)

Photographs of actually installed equipment configurations are included in this chapter to give the reader a practical perspective. Safety in working with HV equipment is the main topic of Chapter 7.

The safety of personnel who work with HV protection equipment is a paramount concern for supervisors and managers responsible for technicians and field personnel.
