What is this symbol?
(OP)
Hi all!
Please refer to the attachment.
This is a 6600 V switchgear, built in the 40's. In it, there are neon ground lamps witch appears to be inductively coupled to the bars. We're wandering what this capacitor-like symbol represents? It is not possible for us to inspect these devices without a total shutdown.
Anybody here ever seen this?

HRC fuses are expensive and if you can get by using this "device" - why not?

Radar use in a modulator
The spark Gap when there was a high current level ionized the gas inside it and arced across the gap and this avoided destroying the modulator when there was a high current draw.
When they ionize one time you have to replace them. Or they just keep arcing but at a lower current.
This must of been a painful experience only reason i remember this.

I think I know how you got your handle! Clipping to those bus-bars with no fuse would probably change your handle to burnt3x or burnt4ever!

In some older equipment in the wraping of the insulation of the bushings, they would insert a metal foil and use it as a potential source.
The bushing acted as a condencer voltage divider.
Condencer bushings work somewhat well as long the secondary load dosen't change.

Gunnar, yep, twice is perhaps all that I could handle.
