Electric Train Supply or ETS is the supply of electricity
which powers electrical equipment on a train. It is usually
provided by the locomotive, and used to power auxiliary
systems on the rolling stock, usually coaches.
Originally, trains hauled by a steam locomotive would be
provided with a supply of steam for heating the carriages.
When diesel locomotives replaced steam, the steam heating
was supplied by a boiler - either oil-fired, or heated by
an electric element in the case of diesel-electric
locomotives. At this time lighting was powered by batteries
which were charged by a dynamo when the train was in
motion, and buffet cars would use bottled gas for cooking
and water heating.

I have one ct of ratio 3000-2000/1 Amp its knee point voltage mentioned on name plate is 500-333/30mA-50mA at Vk/2. in secondary box there is three terminal named 1S1, 1S2, 1S3 then on which terminal obtained the knee point voltage ie 1S1-1S2 OR 1S1-1S3 & also specify the knee point voltage for the ratio 3000 from name plate.
