2. History of DLW DLW is production unit under ministry of railway. This is set in collaboration with AMERICAN LOCOMOTIVE COMPANY (ALCO) U.S.A in 1961, in ancient temple city Varanasi. First locomotive in rolled out in 1964. D.L.W is only manufacture of Diesel Electric locomotive with both ALCO and General Motors Technologies in the world. DLW got its first ISO certification in 1997.Recently DLW has obtained “Integrated Quality and Environment Management System” certification based on ISO-9001 and ISO-14001 in dec,02. DLW exports Locos to SRILANKA ,MALAYSIA, BANGLADESH, TANZANIA, VIETNAM.

4. Diesel fuel The word "diesel" is derived from the German inventor Rudolf Christian Karl Diesel who in 1892 invented the diesel engine. Diesel, or diesel fuel, is any fuel that is used to operate a diesel engine. Most commonly, it refers to a specific liquid fuel obtained by the fractional distillation of petroleum, often called petro diesel. Alternative diesel fuels not derived from petroleum are biodiesel and biomass to liquid (BTL) or gas to liquid (GTL) diesel. Diesel and petrol both are petroleum product. Yet diesel is more used.
5. LocomotiveA locomotive is a railway vehicle that provides the motivepower for a train.The word originates from the latin loco – "from a place" +Medieval Latin motivus, "causing motion", and is a shortenedform of the term locomotive engine.The first successful locomotives were built by Cornishinventor Richard Trevithick.Locomotive in India consist of electric anddiesel locomotives .Steam locomotives are nolonger used, except in heritage area.Locomotives are also called locos or engines.

7. MRS LTS My four week training was confined to three different sections EMS
8. Main Receiving Substation(MRS)• MRS receives main supply from UPPCL at 33kv. Earlier it was UPSEB.• This is step down with 7.5MVA transformer. The 33kv feeder is transformed is two 11kv feeder with a bus coupler in between.• The MRS follows the ring type distribution system for supplying power to DLW. The advantage of ring type system is that each substation is fed from two sides. If in case one line is faulted then the substation is fed by other line. But major disadvantage of ring type system is that it is too costly.

12. CIRCUIT BREAKERIt is an automatic- operated electricalswitch Designed to protect an electricalcircuit from damage Caused byoverload or short- circuit.Circuit breaker, electrical device that cut offthe electric current through electric circuitunder abnormal condition. They are classified as:-  Low voltage CB Medium voltage CB High voltage CB Oil circuit breaker
13. There are 3 DG sets in DLW IT CONSIST OF:- Cylinder Alternator VCB Prime mover Compressor Transformer Cooling tank Breather Panel Natural grounding relay Load Cylinder Horse power 1780 16 2600 HP 850 12 1200 HP 2250 16 3500 HP
14. COOLING SYSTEM • There is a RADIATOR COOLING system:- in this system Mobile ( gets cooled by) Chromate water (gets cooled by) Raw water
15. Control PanelControl panel is a flat , oftenvertical area where control ormonitoring instruments aredisplayed.PROTECTIONMETERING & INDICATIONBREAKER
16. RELAYS : Relays are used for protection of the power system fromdifferent faults which are occurring in the power system. Arelay is a simple electrochemical switch made up of anelectromagnets and a set of contacts. Relays are foundhidden in all sorts of devices. TWO TYPE OF RELAY USED IN MRS :- (QUANTITY AND AMPLITUDE)  Definite relay  Inverse relay
17. CAPACITOR BANK:- In the electrical system the power factor play a important role because byimproving the power factor one can reduce losses . Generally power factorshould not be brought below 0.8 for industrial loads. To improve powerfactor, capacitor bank are placed in parallel with the power supply. InDLW, 600KVAR capacitor bank is used for the improvement of power factor. Reason for Improvement of Power Factor:Reduced lossesReactive power decreased active power increasesEfficiency of machine increasesAdvantages of Using Capacitor Bank:Easy to increase the capacityReliability of the system is highControlling of bank is easyMaintenance is easy
