An autotransformer is an electrical transformer with only one windingThe auto Greek for self prefix refers to the single coil acting alone not to any kind of automatic mechanismIn an autotransformer portions of the same winding act as both the primary winding and secondary winding sides of the transformer.

This book contains examples of control circuits motor starting switches and wiring diagrams for ac manual starters drum switches starters contactors. Reduced voltage and wye-delta motor starters can help limit this inrush current by applying a lesser voltage to the motor for a brief period of time to while the motor gains speed before applying full rated voltage. This two-day seminar was created to bring students up to speed in their electrical troubleshooting skills as.

Readers are encouraged to identify these in. Available in both virtual and in-person instructor-led formats this hands-on Electrical Troubleshooting Preventative Maintenance course allows students to work with real-world components while learning how to fix electrical problems quickly and safely.
