The motor will draw a high starting current until it has run up to full speed. This starting current is commonly around six times the full load current.To reduce the inrush current, larger motors will have reduced-voltage starters or variable speed drives in order to minimise voltage dips to the power supply.
DOL starters uses upto 5 HP motors.Star/Delta starters uses at above 5 HP motors.
DOL starter starts the motor in directly at on line.But Star delta starter starts the motor at directly and works at star and after 5 sec works at delta .

what is KSR type transmission tower? What is LSR type transmission tower?
in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
