CONSIDERATIONS IN THE DESIGN OF H.V. A.C. ELECTRIFICATION FOR THE SOUTH AFRICAN RAILWAYS

The reasons for the South African Railways' decision to adopt hv ac electrification for the Ermelo-Richard's Bay line and other suitable sections are briefly given. The solution of certain technical problems such as restricted electrical clearances and appropriate insulation levels, reduction of impedance of the catenary system, and limitation of rail to earth potentials is considered. Some of the results obtained from practical tests on an experimental ac electrification section near Vryheid are included.
