It can be estimated how much electrical energy is used in HWS. The magnet may rotate inside the coil, or the coil may rotate in a magnetic field created by a magnet. You do not have the permission to view this presentation. This is the ability of measuring device to detect small difference in the quantity being measured. When the tension load in lines is exceedingly high, such as at long river spans, two or more strings are used in parallel. Injection System—Direct Unit Injector.

Do not by-pass any safety interlocks on the machine. The voltage range from 20 to 30 volts, ac or dc.
Its basic function is to detect a fault condition and interrupt current flow. In substations, it is often desired to disconnect a part of the system for mechaniczl maintenance and repairs.
Traction motors are used in electrically powered rail vehicles such as electric multiple units and electric mechajical, other electric vehicles such as electric milk floats, eleva- tors and conveyors as well as vehicles with electrical transmission systems such as die- sel-electric and electric hybrid vehicles. The Exciter supplies excitation for the main generator. The auxiliary generator supplies a dlw varanasi summer training report mechanical voltage of around 72V for supplying power to charge the battery for the control equipment and to power the locomotive lights.
In order to support this lateral load, strain insulators are used. DG Sets, Loco components and sub-assemblies. In mechanicxl battery there is negative and positive plate. M-mixed; both goods and passenger 4.
DIESEL LOCOMOTIVE WORKS (DLW) VARANASI (Uttar Pradesh)
It does not have any specified current breaking capacity or current making capaci- ty. Remember me on this computer. Process of the locomotive of diffferent type are baranasi to electrical point of view. Disconnectors have provisions for a padlock so that inadvertent operation is not possible lock- out-tag out.

The welding process is easier than other methods because the weldor can clearly see the welding zone. If this differential quantity is equal or greater than the pickup value, the relay will operate and open the circuit breaker to isolate the faulty sec- tion. The magnet may rotate inside the coil, or the coil may rotate in a magnetic field created by a magnet. Argon is used as shielding gas. There is a minimal amount of smoke, fumes, and sparks created by the TIG process.
During braking, the motor fields are connected across either the main traction generator diesel-electric loco caranasi the supply electric locomotive and the motor armatures are connected across either the brake grids or supply line. It can also be used to reverse the direction of motion by pushing the handle in the opposite sense. When a short circuit occurs at any point on the transmission line the current flowing in the line increas- es to the enormous value.
Presentation Description Diesel locomotive tfaining, Varanasi. The industrial training is fit for submission and the partial fulfillment dlw varanasi summer training report mechanical the condi- tions for the award of Bachelor of Technology. Stick welding requires moderate to high skill.
Flame hardening, induction hardening, laser beam hardening. However, for high voltage transmission lines, strings of cap-and-pin disc insulators are used, attached to the crossarm in a horizontal direction.

Impeller is made up of Al-alloy. The shop is divided into two parts: This unit produces diesel electronic locomotives and DG sets for Indian railways and other customers in India and Abroad. Z-narrow gauge 2 ft 6 in 4. The exciter has arma- ture and field windings. It can only be reset after 2 minutes and hence the driver will be held responsible for delay in reaching the next station. Here we are doing hardening of camshaft, connecting rod different small components of cylinder head.
Both involve heating steel to austenite region. On a train, the brake shoes are pressed directly against the wheel rim.
