Automatic Railway Substations [PDF]
Transactions of the American Institute of Electrical Engineers, 1920 This paper reviews the broad range of conditions to which railway automatic substations have been applied and also discusses the economies and operating advantages effected by their use. A description is given of the modern equipment with details of its operation. Special reference is made to improvements in design of control apparatus, to the positive

Air insulated compact substations [PDF]
, 2008 With the known greenhouse effect of SF6-insulated substations, the aim now is to reduce the size of transmission substations using air-insulated designs. In this work, a 400 kV compact substation layout is proposed adopting the lower IEC basic insulation
