  6. Starting Large Motors on board ships Typical starting methods: • Direct On Line (DOL) • Star-Delta • Autotransformer (ATS) • Electronic Soft Starters • Electronic Frequency Drives (VFD) What is the optimum starting method for marine application ?

  7. Inrush current 300-800% In Initial Torque 150-180% Tn Motor Torque Motor Current Direct On Line Starting (DOL) Direct On Line Starting results in High Inrush Current & Mechanical Shock • The high inrush current can result in voltage drops • The high mechanical shock can result in damage to the motor, load and transmission system (gear, belt, etc.). It can also require frequent maintenance.

  8. D Un Y U Y UY= 58% Un t Transfer point Star-Delta Starting Two steps starting: Y connected (58% Un), transfer to Delta (100% Un) • Transfer to Delta by timer - open loop control, which may result in very high inrush current if transfer is done before motor reached close to full speed • Step angle of 30°

  9. Auto-transformer starting Un 100% 21% Voltage Drop 70% 32 Sec. 0 Sec. Autotransformer Starting (ATS) The inrush current of the transformer in an Auto-transformer starter may be too quick for the EVR to respond, resulting in a voltage drop
