Preparation of Power Transformer Specifications


Please join the Pittsburgh IAS/PES Joint Chapter in welcoming Mr. Ronnie Minhaz P.E. and his presentation on the "Preparation of Power Transformer Specifications" on Monday 26MAR18, 6:00 pm at the Westinghouse HQ Building, Cranberry Township PA.

**Please Note: that our Chapter is covering Mr. Ronnie Minhaz’s expenses which requires us to charge for this presentation. The cost is $20.00 each for members, and $25.00 each for non-members/guests . Payment can be made at time of Registration through VTOOLS. Cash or Checks only are accepted at the meeting.  Please make checks out to:  "IEEE Pittsburgh Section". A light dinner is included prior to the presentation at no extra charge.**

The purpose of this presentation is to assist attendees in preparation of Transformer Specifications to procure economical and reliable transformers which meet system needs. By knowing the implications of transformer parameters on operation and on cost, functional specifications can be prepared. Some of the topics covered in the presentation/tutorial are rating, voltages, transformer type, vector group, loss capitalization, over excitation, insulation levels, cooling type, sound levels, tap range, taps in HV or in LV, operation of taps for input voltage fluctuations or for compensation of regulation, impedance, overloads, short-circuit, accessories, parallel operation, alternatives etc. Often the bid with the lowest evaluated cost does not give the lowest operational cost transformer, but a good specification is most influential in achieving this. Specifications should not only reduce the capital cost, should also reduce the operational cost. Specifications should help the maintenance and reduce the maintenance cost. To repair a transformer quickly at a low cost should be an important aspect in finalizing an order and to be covered in the specifications. A clear specification with all system requirements is of at most important in procuring reliable and economical transformers. A specification with no ambiguities and with no missing information avoids manufacturing design engineers to assume the requirements which are not clear or missing. When the manufacturing design engineers have to assume, most likely they will assume to obtain the lowest cost transformer, often this does not meet the system needs.
