Why starter?
When DC Motor is suddenly connected to a supply source,
it creates stresses on the armature and supply system.
Since at standstill the armature is not developing any back
e.m.f, so the more current than the rated current
and this will cause damage to the motor.
What the starter do ?
A Motor Starter is used for the smooth starting of a motor.
It consists mainly of a variable resistance placed in
series with the armature.
The purpose of this resistance is to restrict the armature
current to a safe value for starting and accelerating.
The other uses of using a Motor Starter is
· To disconnect the motor in case of an overload
· To disconnect the motor when the supply voltage fails
· To disconnect the motor when the field current is reduced
beyond limit.

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
