Energy Conservation Non-Traction
Last updated on May 23rd, 2017 at 11:06 am Usage of Energy in Indian Railways is basically under two heads namely Traction and Non-traction and measured separately. Traction Energy is consumed towards hauling of trains whereas Non-traction energy is towards offices, railway station, yards, residential, water supply, air conditioning, workshops, maintenance depots etc. The energy […]
Electrical Protection System -Train Lighting and Air Condtioning
Coach Train Lighting 110V system is used for train lighting with floating potential. Positive and negative circuit runs separately on two different side panels of the coach and comes together only near lamp, fan and switch. A fault in one wire will not cause any problem but as soon as there is occurrence of another […]
Electrical Protection System – Tap Changer Locomotive
Last updated on April 5th, 2015 at 06:13 am Protection system of Tap changer locomotive is primitive based on the technology prevailing during 50s. This was imported along with WAG1 class of locomotive and continued to be followed with all class of locomotive developed later on. The protection system comprises of instantaneous relay detecting over […]
Electrical Protection System
Last updated on July 18th, 2013 at 04:01 pm Electrical protection system is to identify the changes in the current and voltage parameter as a consequence of a fault which may result in damage to the equipment and beings. The detection then result simultaneous isolation of the faulty equipment. There are four aspects involved in […]
Electrical Protection, Fire and Safety
Last updated on April 5th, 2015 at 06:13 am Electricity becomes unsafe when current finds path towards non-intended route. Electrical Circuits are designed for systematic current flow. If current escaped the designed path, it becomes a potential cause for unsafe working and fire. Protection system detects any unusual variation in current and disconnects power supply […]
Energy Conservation
Last updated on November 21st, 2014 at 10:40 am Energy Conservation is defined as “To limit and ensure efficient use of energy sources and economic harness of an abundant source of naturally existing renewable sources of energy” Thus there are three areas of research, development and action for Energy Conservation Human behavior for cutting need and reducing […]
Traction Mechanics
Last updated on November 21st, 2014 at 08:15 am Traction Mechanics is the study of train motion. The mechanics involves conversion of overhead electrical power/diesel/steam power in rail horse power to haul a train encountering acceleration, train, grade, curve resistance and similarly braking. Traction Mechanics involves concept of train resistance tractive effort braking effort adhesion […]
