Tower Grounding Training For Telecommunications Networks

Tower Grounding

This Electrical Grounding For Telecommunications Applications training course is based on the CEC or NEC and is designed to give students the latest information on the design, installation and maintenance of electrical grounding systems in telecommunication networks.

The Electrical Grounding For Telecommunications Applications course that will define and completely explain grounding and bonding for telecommunications systems.

It will provide information for the installation of a grounding and bonding system for communications infrastructure. The course will include requirements for providing a permanent grounding and bonding infrastructure for communications circuits, raceways, and cable tray.

This course will provide the participants with a good understanding of the principles of lightning protection and grounding of telecommunications facilities, such as self-supporting radio towers, guyed masts, monopoles and rooftop antenna mounting frames and structures and how techniques are applied in the field to protect these structures and the associated equipment, staff and the general public.

This training course will explain grounding and bonding requirements in the C22.1-06, the NEC and TIA/EIA/ANSI Standards.

 

COURSE BENEFITS

Improve the protection and operation of your communications facilities and minimize the hazards to your personnel. This course will address electrical and mechanical grounding in central offices, loop access sites like DLCs, buildings, and wireless communications installations such as base station sites and microwave radio installations.

Students will come away with a sound understanding of:

  • The fundamental characteristics of lightning and how to protect against it
  • How power line disturbances can impact communications
  • How to control corrosion through grounding
  • The role of the CE Code, NESC, NEC and other codes and standards
  • Earth grounds and soil characteristics
  • How to provide for a common bonding network in telco sites and buildings
  • The participants will understand the requirements of the CEC, NEC and TIA/EIA/ANSI “Commercial Building Grounding (Earthing) and Bonding Requirements for Telecommunications.
  • The participant will understand the concept of "equal potential grounds" that the industry tries to achieve in a data center telecommunications environment.
  • Proper grounding at radio and antenna sites
