contains a contactor only).
2.protection(it contains over current protection devices.star delta
starter also contains this)
3.less space is required


but it is used only for small motors like power less than 7.5,10Hp

Answer / kapil narayanrao bahadure

the advantages of DOL starter:-This is a protection device.
When motor takes large current from supply, then trip to
suplly.& safe from burn out.
When single phasing occures in the system then become
trip to sypply.by O.L.c.(over load coil).

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
