Abstract :
ELECTRIC traction is considered one of the most widely used means of transportation because of its advantages such as being economical, environment friendly etc. Indian Railways has been using electric traction fed by 25kV single-phase AC supply obtained from three phase utility. This paper analyses the harmonic issues of the electric traction system by measuring voltage, current and harmonics at different traction substations. A passive harmonic LC filter is designed to filter out the prominent harmonics in the system.
