3 was being emptied and tank rise had ceased. A line of sight was established from the readings. Mostof the settlement took place whileinitially filling the tank. Upon furtherrefilling, settlement was limited to a maximum of \%”. Power to this station was provided through a 30 KVA 2400/120-208 volt, 3-phase, 4-wire, 60 cycle transformer. Primary power to the transformer was supplied through an oil fuse cutout from the island distribution system of 2400 volt, 3-phase, 3-wire, 60 cycle. The transformer and secondary distribution panel were mounted inside a waterproof wooden enclosure 22 feet from the outer tank. The circuit breaker distribution panel provided power to Station 23 and the adjacent tent within which a 12-circuit lighting panel was mounted that supplied power to 12 special receptacles. Power for Station 23 ran through a 12-circuit lighting panel with a 60-amp special receptacle for scientific needs. This panel also furnished power for Station Figure 2-38. CHAPTER I!, SECTION 3 1336.04. The total connected power load for the station was 21 KW. Timing signals were provided by one 37conductor cable and a 9-conductor cable, and telephone lines by one-pair conductor cables, terminating in a 26-pair terminal cabinet within the station. Three 2-conductor cables extending from the terminal cabinet provided timing signals for Station 1336.04, Eleven 7 /8-inch aluminum coaxial cables were run between Stations 1611 and 23 and the enclosure on the north edge of the large tank. A twenty foot cable for final hook-up was left at each end. Two portable 500 gpm gasoline-driven water pumps with 6-inch hose connections were used for filling the tanks. Ventilation of the inner tank was accomplished with a 700 cfm blower forcing air through steel pipes. A total of 311 cubic yards of concrete was poured. Station 24-55% Complete Page 2-55
