Isolating a Disconnecting Circuit Breaker using live line working

Isolating a Disconnecting Circuit Breaker using live line working As it becomes more and more common with live working, performed by special trained staff, the question has been raised if it is possible to use the manual links in the DCB-design for live working. In a plant taken into service, a test was performed, where a DCB first was linked off from the live switchgear and then reconnected. The test was documented in this video film.
