(Continuation of Question 6/5) Motivation
In recent years, modern society has experienced a high and steady growth of
dependency on telecommunications. In this context, the reliability of
telecommunication services has become an issue of high priority. Bonding and
earthing of electronic equipment inside telecommunications buildings and
customer premises is one way to achieve this reliability.
The evolution of the power architecture of present and future ICT systems leads
to the need to study the impact of the new power architecture, operated by
direct voltage current (DC) or rectified current sources, on the bonding and
earthing of the equipment.
Furthermore the evolution of telecommunication network leads to the need to
study bonding configurations and earthing of remote sites in co-location
environment and of telecommunication centers.
This Question impacts climate change issues by ensuring that the adequate
resistibility requirements for equipment and protective measures for
installations reduce the amount of equipment and installation damage. By
reducing damages less fossils fuels are burnt (personnel do not have to drive to
a site to repair equipment) and less manufacturing is required (less replacement
equipment is needed).
The following Recommendations and Handbook, in force at the time of approval of
this Question, fall under its responsibility:
- K.27, K.35, K.66, K.73 and “Earthing and Bonding Handbook”.
Question
The purpose of this question is to produce new recommendations and to revise the
existing ones regarding the bonding configurations and earthing of electronic
equipment inside telecommunication buildings and customer premises as well as
remote electronic sites.
Study items to be considered include, but are not limited to:
- Bonding configurations and earthing of remote sites in co-location environment
and of telecommunication centers;
- Guideline for earthing and power feeding systems in co-located environment;
- Maintenance methods of bonding configurations and earthing.
Tasks
Tasks include, but are not limited to:
- One or more Recommendations on bonding configurations and earthing of remote
sites in co-located environment and of telecommunication centre;
- Maintenance and enhancement of existing Recommendations K.27, K.35, K.66 and
K.73 with better linkage and coordination between these recommendations and
other recommendations within the K-series;
- Maintenance and enhancement of "Earthing & Bonding Handbook".
