Electrical Engineering and Railways
How Resistance is important in understanding Electricity?
Resistance is the hindrance in the flow of electron and is similar to friction in mechanical movements. It is the property of a substance due to which it opposes (or restricts) the flow of charge or electrons through it. In metals, there is a significant presence of free or loosely-attached electrons in their atoms which […]
Where to begin to understand Electrical Engineering?
One need to understand a few fundamentals on which the entire electrical engineering is built over the period
Indian Railway Context – Sanding to improve adhesion
In Indian Railway context, sanding is one of the important design and functional requirement to improve adhesion between rail and wheel during traction. The requirement has gone so deep in the background of policy makers that it is difficult to believe a traction equipment without sanding gear. Any case of an investigation into wheel slipping/stalling […]
Mechanized measurement and inspection – a help to cut down maintenance cost
Last updated on March 16th, 2019 at 10:00 am Failure of integration of new technologies with the traditional system of working is the main reason for Indian Railways failure to cut down cost. Introduction of new technologies in any system cannot be done overnight and is always a well-planned engineering process. If not, both system […]
‘Rescue’ Indian Railway passenger business through statistical indices ‘RSKU’
Last updated on March 19th, 2019 at 11:48 am Is Indian Railway earning fully towards its non-sub-urban passenger business? There is no published data to corroborate this. Interpreting it by the long waiting list is a wrong assessment. The waiting list continuing in 2016-17 even when there is a drop of 10% passenger as compared […]
Wheel Slipping and Stalling of trains-an age old problem of IR
Last updated on March 19th, 2019 at 12:10 pm Wheel Slipping and Stalling Wheel slipping and stalling of freight trains is one of the major hurdles in running of trains during a certain period of monsoon and dew during early hours of winter. Such happening is accepted as seasonal with stereotype repetition of age-old instruction […]
Has Solar Power taken off to drive transport sector in future?
Last updated on March 25th, 2019 at 05:27 am Most of the modules for tapping using solar power available in the market have been developed for a wide range of applications in Industry, residential and office complex. These modules may not immediately suit the Railways need for a few specific applications. It is, therefore, necessary […]
Selection of Suspension Arrangement of Traction Motors : A Right Approach
Abstract Motor suspension arrangement is of paramount importance for the reliability of traction motors. Another vital input for the selection of traction motor for given motor suspension arrangement is its rotational speed. Non-availability of any complied information on the relationship of rotational speed of traction motors and their mounting arrangement makes the jobs of Rolling […]
Electrical Engineering and Railways
Last updated on April 5th, 2015 at 06:18 am Electrical Engineering is the field of the study of generation, transmission, distribution and use of electrical energy. Electrical Engineering in Railways made its beginning with the responsibility of illumination and ventilation at Railway stations, offices and residential complex and water supply. Thereafter, illumination of passenger carriages […]
