Abstract
268,305. Akt.-Ges. Brown, Boveri, et Cie. March 29, 1926, [Convention date]. Oil switches. - In order to limit the gaseous pressures produced on break in an oil switch the air volume above the oil surface in the switch container (or total volume in all the containers where there are two or three switch tanks) amounts for each 100,000 maximum three-phase kVA rupturing capacity to at least 50 + 1/6 E litres (or in the case of single-phase current to 2/3 of this amount), E being the rated line voltage of the switch in kV.
