We recently had a Shut-down in a local factory, to upgrade the 11kV/400V tranny,
after the work was done and the transformer was re-energised, I had the task of throwing the Main Isolator,(a heap of remedial work, had been done in the factory),and as I went to throw the switch,
(a 1000A ACB), it got stuck half-way,resulting in a flash and a bang!.
How do you guys feel about throwing High current Isolators?, personally they give me the Willies.
Your thoughts please?.
