Auto Transformer Starters, Feature : Accuracy, Adjustable, Durable, High Quality, Long Working Life

Motor is connected in delta from the start. Auto transformer provides voltage to the motor at start. Appropriate lower voltage tapping –customized as per the application – is provided to the motor. After the motor has attained significant torque changeover from auto transformer to on line takes place. The changeover is “closed transition” i.e. During changeover the auto transformer acts as a choke supplying voltage to motor – hence smooth or stepless or soft starting takes place. The motor then runs on line current. The transformer is isolated from both the ends to protect the contactors. Adjustable high torque: a high torque (up to 64%) possible and can be customized by voltage tapings. No power quality issues: all standards electrical components ensure that there are no harmonics or other power quality issues. Transient elimination: korndorfer closed transition technology ensures that transients are eliminated. Motor protection: motor is connected in delta at the time of starting to avoid high inrush current in the motor winding thus providing lesser heat generation. Reduced voltage starter: voltage controlled by auto transformer at the time of starting. The capicity of ats is 15hp to 1000 hp rs. 1111/- per hp for any starter.
