What THiD would be expected with 200% current limit on a soft start?
When sizing soft starters, THiD levels are impacted by the current limit setting. The THiD using a 200% current limit on a soft start would be about 20% (about 33% less than using a 300% current limit). Adjusting the current limit setting down on a soft starter helps reduce voltage distortion on transient voltage dip issues while operating on a generator.
