The burnt capacitor one is interesting.... we are seeing similar things at work with the pfc caps in the quad ceiling tile type flourscents. I'm wondering if this is down to triplen harmonics ... those caps are going to have a much lower impedance at 150Hz and so will pass a much larger current than the designer anticipated.

That's about the fifth cap. I've seen like this on the site.

Ditto, spotted some today where the plastic case has fallen off the cap & is sitting on the upper side of the tile diffuser...... Guess I'll go have a closer look at them....

Easily resolved - the firm refuses to pay the invoice.

What cause the problem with the brick light?

What cause the problem with the brick light?

Corrosion from salts and lime in the bricks and mortar I suspect.

Brick lights are the worst invention ever invented. I've never had anything but trouble with them.

A couple of years ago our work had a recall from crompton about the capacitors in their fittings melting/burning, the brand affected were labelled as DNA, we ended up getting sent a load of replacement capacitors ( different brand) as we were finding them popping everywhere and were advised to replace them due to the fault.
I dont actually know what caused the failure.

A leaking roof over an 11kv Circuit breaker casued the mech casing to start to desolve.

A female 11kv circuit breaker contact after opening/tripping on a fault.....Actually not that badly damaged and have seen worse put back into service

a 1937 11000/415V Transformer that has spent the many many years with a low oil level

And whats more or less an 11000v Connector block having its TAR compund melted out
