Recommendation K.11



1.	Add a new paragraph to point 1.6.3:



	"To avoid disturbances in telecommunication circuits caused by striking protective devices, the striking 
voltage values and the numbers of arrestors should be considered."



2.	Add new point 2.6:



"2.6	Recommended policy



	Where lines in a telecommunications network are exposed to frequent or severe disturbances from 
power line faults or lightning, the voltage of these lines relative to local earth potential should be limited

construction methods for the line."
