DrG, what camera do you use?

Im not sure if this qualifies as interesting, but got a few shots from my canon rebel that I thought I'd share...

Here is a long exposure of a lighting storm while I was in Texas.

and here is some shots I took while exploring some storm drains.

One rather dramatic sunset taken from my hotel window while working in Sweden a few weeks ago.

A rather more normal one, zoomed in on the bridge between Sweden and Denmark:

I was generally minimising sightseeing with the present situation, but I had to go to the local shopping centre for food & got this from just outside an entrance - it's Malmo Emporia, which curved notches? in places around it.

This view with the sun & clouds was just too good to miss:

The pictures of .22 shells used as fuses in another thread reminded me of these - "Shotgun shell" fuses!

I've no idea of the formal name for them and several specialist fuse suppliers have searched for them but have no record of anything like them, so the holders were replaced. They are from equipment dating to probably around the 1940s.

They may have been something to do with the railways .. .. .. .

My father spent the war years as a signalman near Warwick and I've seen those before in his gear

I worked for a switchgear manufacturer in my early working life and we had a unit called a T4GF3 (I think) which was a fused ring main unit - 3 phase 11kV 630A normal current. It had 3 fuses feeding the transformer outlet at the back. These had an explosive charge which fired a pin out of the end to trip a mechanism to prevent loosing a single phase. The fuses were (from memory) 14" (~35cm) long and 2.5" (6.2cm) diameter. One of the jobs I had was to design a simulator of the explosive pin and then a compound pendulum to measure the energy transferred. BTW, the fault current was 21kA!!!

Edit, found a picture of one.

Got enough padlocks on it

Got enough padlocks on it

That's probably how it was in service. If it's not locked someone (normally kids) will find a way to switch it. Also, the top is both bolted and locked down for the same reason. When I worked there, one Monday we got a fault report from a switch that had failed (!!!!). Three 10 year old boys had decided it would be funny to blackout the area and the switch had an oil level indicator on the front. They broke the indicator and poked umbrella spokes through the hole. When the spokes reached the bus bars, the oil (250L) instantly boiled and ignited. All three were killed in the subsequent explosion. After that, all access points had to be locked and the oil level indicator removed.

Actually, that's probably how it was taken out of service as all switches are in the earth position ensuring the cables are both dead (not live).
