Summarization request:
Please summarize the process of how an electric locomotive draws power and converts it to mechanical energy, as well as the equipment used to control its speed.

Source text:
The electric locomotive draws power from the over head equipment (OHE) with the help of Pantograph and converts this electrical energy to mechanical energy, in controlled manner, through Traction Motors which drive the axles.
To enable the locomotive to perform this task, it is equipped with suitable equipment, which enable loco pilot to control the speed of the train as per requirement by controlling the applied voltage to traction motors.
In conventional locomotives, 25KV, Single phase, AC supply is collected by a roof-mounted pantograph from the OHE and is stepped down by a transformer inside the locomotive.
This supply is then converted to DC supply by a full wave silicon rectifier and associated smoothing filter before being fed to the traction motors.
Torque / speed control is achieved by variation of the AC input voltage to the rectifier through an on-load tap changing arrangement on the primary winding of the loco transformer.
The equipment on electric locomotive, depending up on where it is located, can be classified in three different categories viz.
1. Roof equipment,
2. Inside equipment and
3. Under Frame equipment
Both the roof and the under frame equipment are subjected to lot of dust and atmospheric pollution and are therefore designed to withstand these severe working conditions.

kripaya is prakriya ko sankshep main prastut karen ki kaise ek electric locomotive bijli khinchataa he or ise yantric urja main parivartit karata he, saath hi saath isaki gati ko niyantrit karne ke liye upyog kiye jane vaale upkaran bhi.

strot ibaarat:
electric locomotive pantograph kii madad se over head equipment (oechai) se bijli khinchataa he or is vidyut urja ko yantric urja main, niyantrit tareeke se, karshan motors ke madhyam se, jo eksal ko chalaata he, ko niyantrit karata he.
is kaary ko karne ke liye locomotive ko sakasham karne ke liye, yah upyukt upkarnon se susajjit he, jo loko payalat ko trection motors ko lagu voltage ko niyantrit karke aavashyaktaa ke anusaar train kii gati ko niyantrit karne main sakasham banaata he.
paaramparik locomotive main, 25kv, ekal charan, AC aapurti ko OHE se ek chat-mounted paintograph dwaara ekatra kiya jaataa he or ise locomotive ke andar ek transfarmar dwaara neeche le jaaya jaataa he.
is aapurti ko tab ek purna wave silicon ractifire or sambandhit smoothing filter dwaara disi aapurti main parivartit kiya jaataa he, jise trection motors ko khilaayaa jaataa he.
toq / gati niyantran asi input voltage kii bhinnata dwaara ractifire ke liye praapt kiya jaataa he, jo ki loko transfarmar ke praathmik ghumaavdaar par ek on-lod tap changing vyavastha ke madhyam se hota he.
electric locomotive par upkaran, jahaan yah sthit he, us par nirbhar karata he, ise teen alag -alag shreniyon main vargeekrut kiya ja saktaa he.
1. chat upkaran,
2. andar upkaran or
3. frem upkaran ke tahat
chat or under frem upkaran donon ko dhul or vayumandaleey pradooshan ke adheen kiya jaataa he or isliye ise in gambhir kaamkaaji paristhitiyon kaa saamana karne ke liye dizine kiya gaya he.

electric locomotive paintograph kaa upyog karke overhead taron se bijli praapt karte hai.yah vaikalpik vartmaan pratyaksh vartmaan main parivartit ho jaataa he, jo eksal ko modane vaale karshan motors ko shakti pradaan karata he.voltage ko shuru main ek transfarmar ke rup main janaa jane vaale upkaran dwaara kam kiya jaataa he.baari -baari se karant ko ek ractifire or filter dwaara pratyaksh vartmaan main thik kiya jaataa he.locomotive kii gati ko transfarmar main input voltage ko samyojit karke viniyamit kiya jaataa he.
paintograph or trection motors ko kathin paristhitiyon ko sahan karne ke liye banaaya gaya he.mukhya ghatakon main shaamil hai:
chat (paintograph) par upkaran bijli main le jate hai.andar, ek transfarmar voltage ko katata he, ek ractifire ise pratyaksh karant main parivartit karata he, or ek tap changer gati ko niyantrit karne ke liye transfarmar ke input ko badal detaa he.
frem (trection motors) ke neeche upkaran eksal ko ghumata he.chat par or frem ke neeche upkaran pradooshan or malbe ko sambhaal sakate hai.
