DC vs AC interruption
7
AC interruption:
Capture the swinging mass in its outer position
(current zero)
Zero kinetic energy – Max potential energy
DC interruption:
Oppose the motion of a linearly moving mass -
--> counter voltage
15 kA in 100 km line = 11 MJ
= 30 ton train at 100 km/h

WP 5, 10, 11 WG 64 62271-313 circuit breakers
• Set of requirements defined that covers all stages of current interruption
• This set is applied to testing of HVDC breakers up to 320 kV 20 kA
• Analysis made based on experiments on internal stresses on key components
• Lessons learned- transferred to CIGRE WGs on DC CB
HVDC WG finished early 2021- transferred to IEC MT on DC CB
draft standard end 2020
