_____________
1 Scope
Add, after the last dashed point of Clause 1, the following new note and paragraph:
NOTE CIGRE Technical Brochure 368 [2] presents a study about the operating environment of voltage grading
capacitors applied to high-voltage circuit-breakers.
This standard does not apply to phase-to-earth capacitors installed on the circuit-breaker to
modify the Transient Recovery Voltage.
7.4 Minimum withstand value of mechanical bending load
Replace existing Subclause 7.4 by the following new text:
7.4.1 Capacitors mounted on air insulated circuit -breaker
The test bending moment M shall be calculated as follows:
c
m 1
 
M = 100+ ×g× ×l
 
C
2 0,7
 
where
M is in Nm;
c
l is the length of the capacitor in m;
