Question Why a starter is used for a motor?
 Question Asked In Companies :: L&T,     < I also faced this Question! >
 Question Submitted By :: ravi
  Answer Posted By  
 
Answer
generally the resistance of armature is very small i.e in
term of .05ohm or like this.this is due to reduce the
losses.if the motor is connected direct supply high current
will flow and it may burn the armature winding.thats why
starter is connected between supply and motor which reduces
the starting current and provided smooth operation

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics.

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? 249
