I'd have tought any sensibly designed system would have a way of doing this designed in. Pesumably one would connect a suitable load and allow time for discharge.

Very, Very, Very carefully........

John.

I once got a nasty pounding from a TV set when I accidently crossed the cap with a screwdriver.

Perhaps you could have an idiot run about with screwdrivers in hand.

Oh, yes my mistake.

Perhaps you could have a few idiots run about with screwdrivers in hand.

With the capacitor bank deenergized, the individual capacitors are short-circuited between their insulated terminals and tank and the tanks grounded. If the capacitor tanks are mounted on ungrounded racks, the racks must also be grounded. The internal resistance should never be depended upon to discharge deenergized capacitors. If grounding means are not built into the installation (through switches or sphere gaps, for example), this work is typically done with insulated ground sticks (equipped with a suitable electrode attached to a flexible, solidly grounded lead) or an insulated hot stick, similarly equipped. Before working on or handling the grounded capacitors, all the terminals and tanks should be temporarily wired together and grounded.

Finally, and most importantly, only trained, certified, or otherwise qualified high voltage technicians or line personnel should be fooling around with 115 kV capacitors or any other high voltage equipment.

Thankyou, that is exactly how it is done.
