Answer / 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

Answer / piyush rana

You can check the length of the cable from the supply to
motor, I think It will be more so that due to line
resistance loss during starting the line voltage will go
down for the fraction of seconds.
please mention the connected load, transformer capacity,
volatge incoming etc for further clear answer.
