Line Harmonic Filter is connected with Primary
winding of main transformer which consist of resistors
and capacitors.
The Harmonic Filter reduces the high frequency
harmonics to avoid disturbance in signaling. If the
harmonic filter gets by-passed by the system, the
speed of the locomotive will be automatically restricted
upto max. 40 kmph.
The complete Resistor Assembly is mounted on
the roof of the Locomotive. This Resistor is naturally
cooled by air circulation.
The formation of Resistor Element is of special design
i.e. Corrugation type with a certain pretension,
is wound in the form of meanders around
ceramic Insulator which are fixed with transverse
rods on to the frame. The elasticity due to corrugation
of the resistor tape ensures good stability of
its shape, even at high temperature. |
