What reading level is Transformers for Single And Multiphase Currents a Treatise On Their Theory Co book?
To quickly assess the difficulty of the text, read a short excerpt:
We require for B = 1 2000 an exciting force of 4 ampere-turns per cm. , or 468 ampere-turns crest value, that is 332 ampere-turns effective value. Since n = 640 we find ?; = 0'52 or 2*6% of full load current. This is permissible. The case for this transformer would be 100 cm. X 60 cm. And about 140 cm. High. Allowing for corrugation, the surface wetted by oil would be about iioooo sq. Cm. Since the drop from oil through case to air is to be 25, the specific cooling surface is . 25 that is to sa...y, the case can dissipate noooo 60 = 1 840 watt leaving 1320 watt to be taken up by the cooling water. The worm will be a pipe of i" diameter, and have a total length of 12 yards. With a 5 rise in the tempera- ture of the water (10 at inlet and 15 at outlet) we ENLARGING A DESIGN 141 require 240 litres, or 54 gallons, of cooling water per hour. The weight and cost of active material will be as follows : Iron . . 580 kg. . . 5805-. Copper . 300, , 5255-. 880 uo5
