we have a 400hp, 380v asynchronous motor supposed to drive a compressor (Full load current about 520A). We have installed Cutler-Hammer S801 series soft start for a smooth start. But starting current still remains a concern. How much amps our utility must supply in order to be sure that the starting current will not cause a problem when we use ramp start or kickstart mode?
Also Assume our utility can just supply about 500-600 amps. Can we use current limit option in soft starter to ensure that there will be no problems during start?
There is another question I didn't want to start a new topic for. Is distance a concern in selecting an ignition wire? Is there a standard for burial of ignition cables? And what other factors are required when selecting an ignition wire for a flare/ burn pit system?
