Auto transformer an auto transformer is a transformer with only one winding wound on a laminated core.

Schematic diagram of auto transformer starter. Auto transformer starter control wiring and power wiring diagram kaise kare duration. Most of the auto starters are provided with 3 sets of taps so as to reduce the voltage to 80 65 or 50 percent of the line voltage to suit the local conditions of supply. The inrush current in wye is reduced to 33 of what it would be if the motor was started with an across the line starter.

Assortment of 3 phase motor starter wiring diagram pdf. What is auto transformer starter. An auto transformer is similar to a two winding transformer but differ in the way the primary and secondary winding are interrelated.

3 phase motor starter wiring diagram pdf. Circuit and function an auto transformer starter makes it possible to start squirrel cage induction motors with reduced starting current as the voltage across the motor is reduced during starting. Ryb electrical 450141 views.

In this method the starting current is limited by using a three phase auto transformer to reduce the initial stator applied voltage. In contrast to the star delta connection only three motor leads and terminals are required. A part of the winding is common to both primary and secondary sides.
