I have tons of pics of regular construction stuff but rather than bore everyone with that I am waiting till we do some of the unusual stuff. I did think you might enjoy these.
Picture one: One (of two) 300KVA Mirus harmonic canceling duel output transformer. This transformer has two 180KVA outputs phase shifted 30Deg from each other. One is 15 degrees out from the primary the other is 45 degrees out. The concept here is that the two outputs create a common mode rejection point to cancel 3rd 5th 7th etc. harmonic currents rather than allowing them to circulate in the primary delta winding as a normal transformer would. This eliminates the need for a high K rated transformer and filters noise out of the grounding system. Notice all the secondary terminals!
Picture two: The point where the 12" ground strap emerges from outside into the building. You can see one of the four rows of seismic rack bases for this room. At each one we will bolt and silver solder a 12" tap run down the inside of the bases. Each rack has a ground bus in it with a 2" copper strap silver soldered to it which we will silver solder to the 12" under the bases. Pics will follow.
PS: The silver solder we are using costs $32.00 per pound!
