4.cost.

Answer / sathish

1. cost is less
2. compact in size
3. operation is easy
4. time of operation is less

Answer / jkth

main advantages of dol starter are
1.cost is less(star delta starter contains 3 contactors,a timer dol
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).

Answer / v.balakrishnan

The only advantage of DOL Starter is that the cost compare
with Star Delta & Soft Starters.

Answer / muthupandi1418@gmail.com

1. low cost (compare star delta stater)
2.simple operation
3.troubleshooting easy
4.easy maintance
5.compact size
6.over current protection
7.line voltage direct apply to motor terminal .

Answer / elangkumanan

dol starter adventage that is motor protection device
another OL Relay, contactor, motor safe purpose use that is
adventage to dol starter.

In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.

A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
