Re: Relocating office...
all CRTs where flickering like hell whenever a train passed
Pa, that's nowt. Try welding current being passed through the frame of a steel portal building.
"A few" years ago, our offices were being expanded - the factory & warehouse kept moving along into new extensions, then office were extended into the newly vacated bits. The contractors decided on "belt and braces" so welded all the joints as well as bolting them. Cue 'kin big welding transformer with welding earth cable just clamped to the nearest bit of framework while the welder goes round all the joints. The magnetic field has "very interesting" effects on the CRT screen the other side of the wall - "wobbling" the picture right off the screen !
