16.67 Hz and 25 Hz systems are supplied from three-phase commercial AC systems with stationary converters of 50/16.67 Hz or 60/25 Hz.
On the network side, these converters always contain a three-phase input converter transformer and a single-phase special output transformer on the catenary side. These transformers are specially designed for the converter technology and follow generally the principles of a variable speed drive transformer.
