Can Star-delta starter use for a 20kW Motor (For a powder
mixer machine) cause voltage-dip in the supply line voltage?
If so, what are the recommended solution to
eliminate/reduce the transient voltage dip in the line
voltage?
Answer Posted / tushar patil
yes u can use star delta starter
20KW means 30HP motor
u can use VFD (variable frequency drive) also
it is very easy to u
if cable length is more than 50 m then u should connect output line chock to output n input line also connect line chock..
n increase accelaration time in vfd
