Special Designs: Auto-Transformers

About the Topic
Electric Power Generation in the US has seen a constant increase in installed capacity during the past century. The load centers being remote from the generating stations, combined with the increase in power generation naturally resulted in extensive transmission networks, thus the need for transformers of large capacity. For better reliability and economic viability, the various isolated high voltage power networks are inter-connected by means of Auto-Transformers.
Though the advantages of Auto-Transformers have been known for a long time, they were not used as power units but only as auxiliary devices for fine voltage adjustments, for starting induction motors and so on. The recent de-regulation of the utility industry, however, has caused major changes. Utilities have merged to consolidate their resources, which resulted in superimposing power grid(s) on power grid(s), further increasing the demand for larger capacity network/grid inter-connecting Auto-Transformers.
The fact that Auto-Transformers have weight and overall dimension that is less than 2-winding transformers of the same outputs permits them to be produced with a considerably larger capacity per unit. Auto-Transformers, however, call for several unique design considerations which require special attention and careful study. Auto-Transformers discussed here are those of core form design and Y-connected for high-voltage networks and serving mainly as inter-connecting transformers.
About the Speaker
Mr. Sanjay Y. Patel is the Manager, Electrical Design-North America for Smit Transformers. He received his B.S in Electrical Engineering (Major "Electrical Machine Design") from M.S. University of Baroda, India in 1985. His graduate work thesis was on "Manufacturing Process of Power Transformers". He joined Smit Transformers in 1993, and has been mainly responsible for electrical design of transformers from 10 MVA up to 1000 MVA, BIL 1675 kV. Prior to joining Smit, he worked as a Design Engineer for Nik-San Engineering in India and as a Design Engineer for L. Wilson Power Corporation, Minneapolis, MN and Magnetek Ohio Transformers, Rancho Dominguez, CA. Mr. Patel has authored several papers on the subject of transformer design. He is a member of IEEE Transformer Committee.

Directions to Luncheon Location
You can reach the 24th floor of 55 East Monroe Street from the South
(Adams Street entrance) elevator bank only.
Please bring your lunch with you. If you would like to purchase lunch,
then the Under 55 dining room, in the basement on the North end of the
building, is recommended.
Take the elevator to 24 and sign in with the Sargent & Lundy
Receptionist. Please note that food is only permitted in the
Hospitality Area outside the Conference Room. Food is not permitted
in the Conference Room.
As you sign in, you may request a Discount Parking coupon. When you
depart, you must pay for parking at the Automated Pay Station in the
Parking Garage elevator lobby on the floor where you parked. First
insert the parking ticket, then insert the discount coupon, then make
payment. If you pay at the Garage Exit, then the discount is NOT
available. With the discount, parking is $16, without $36.
Continuing Education
IEEE technical meetings may be acceptable as continuing education where
required for maintenance of professional engineering licensure. Refer to
the individual state's requirements for details. A receipt for one
Professional Development Hour (PDH) will be provided.
