Answer / bipin

it is 1-phase...25kv ac, 50Hz. actually traction substations
are there which recieve 3 phase supply and divide these
phases into sections of about 30-40 kms along the line. each
of these sections are completely electrically isolated from
each other by using dead sections.

Answer / kapil

25 kv single phase ac.converters are installed in engine because we need ac also to supply auxiluries like blowers etc.
