During he starting up of the motor, the upstream's MCCB
(350A) always trips due to the UVT relay activated.
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 / 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.
