CaOperator,
Thanks for that explanation. [Linked Image]
Very complete and informative.
Good to see that you have extra set of eyes during these Disconnections, with HV equipment.
These days, over here in NZ, with alot of our HV grid equipment, the disconnects are operated by UHF radio servo-systems, I don't trust these systems AT ALL!.
Out in the field, I have had incomplete disconnections, caused by one servo-motor not working, but there is no way that the Controlroom operator can know this, unless they are told.
I prefer mechanical Disconnects, for anything above 3.3kV, at least you have direct control over them and you can lock them out at your end!.
Radio control was supposed to make life easier for us Lineys, I have seen more single phases left live, since we got this technology, and at 11kV and 22kV, this is not good!!. [Linked Image]
