Technical DescriptionFunction Q: Star-Delta StartingDescription
On energisation, the star contact closes instantaneously during the timing period T. At the end of the timing period, the star contact opens. At the end of the timing period Ti (interswitching time), while the contact is open, the delta contact closes and remains in this position.Legend
