Continuation of Question 12/5 studied in 1997-2000
Type of question
Task-oriented
Reason for question
The electromagnetic interference between telecommunications
lines and power and electrified railway lines have been studied
by ITU and the results of these studies are reported in the nine
volumes of the Directives and in Recommendations K.33, K.53 and
K.54. There is a need to maintain these documents and to ensure
good coordination between them.
Text of question
This question will revise Volume VI of the Directives
considering Recommendations K.33 and K.53.
The question will also review the suitability of techniques
for testing the immunity of telecommunication equipment against
induced voltages by a.c. power and electrified railway lines
(revision of Recommendation K.54)
Specific objective and time-frame
A new edition of Volume VI of the Directives providing
guidance on limits concerning permissible levels of induced
voltages and currents and on responsibility of different network
(telecommunications and power/railway) operators (2002).
A revision of the recommendation on immunity test methods and
procedures of telecommunication equipment (2004).
NOTE - The revision of the Directives should be done in
collaboration with CIGRE and UIC.
Relationship to other
- Recommendations
- Questions
- International bodies
