Course Summary

Medium and large transformers are custom-built for specific transmission and distribution system requirements. There are many different design approaches, materials and manufacturing processes that can be used to manufacture transformers. These differences can result in varying levels of system performance, power transfer efficiency, fault tolerance, equipment life, cost and the like.

This one-day workshop will provide instruction on fundamentals of transformer design and manufacturing processes to enlighten the attendees on what to look for from procurement of transformer to asset management. The instruction also includes “Preparation of Preparation of Transformer Specification” focusing on key areas should be looked into in writing specification. It will provide insight into specifying the design and manufacture of transformers that are most appropriate for specific system requirements.

Who should attend?
This workshop is designed for engineers especially electrical who work in electrical power industry (Generation, Transmission and distribution). It is also targeted at experienced engineers requiring a refresher course on Transformer and how it’s parameters have impact on power system. This course will clearly demonstrate what can be missed in specification to procure a reliable cost effective transformer as well as the design and manufacturing process that has impact on life of transformer and system performance.

Course Objectives
• To provide a basic understanding of the Transformer design and manufacturing process that has impact on procurement, maintenance, asset management and life cycle of the equipment.
• To prepare specifications for procuring reliable transformers at market prices.
• To know and understand the clarifications/confirmations to ask in the Tender Review and Design Review meetings.
• To avoid delays in delivery by following up with the manufacturer at critical intervals.
• To obtain the best benefits by knowing the characteristics and the costs of the materials and the components used in the transformers.

Instructor:
Mr. Minhaz is the president and founder of Transformer Consulting Services, Inc. He has more than ten years experience in the specification and design of transformers. Prior to forming his own company, he worked as a Transformer Design Engineer at Pauwels Canada (manufacturer), an Equipment Engineer at SNC Lava Lin (ECPM), an Equipment Engineer at Enmax Power (utility), and a Lead Substation Engineer at McGregor Construction (substation construction). Mr. Minhaz holds a BS in Electrical Engineering from the University of Manitoba, Canada, and is a registered professional engineer in the province of Alberta, Canada. He is an active member of IEEE and IEEE Power & Energy Society. He has held various IEEE section-level leadership positions.

Course outline:
Part 1:
Title: Transformer Design and Design Parameters

Abstract:
The presentation will be on the Basic of Transformer Design. The presentation will explain how a transformer designer interprets parameters such as MVA, lightning Impulse, Switching impulse, Percentage Impedance supplied by a customer. It will touch on Power rating [MVA], Core, Rated voltages, Insulation Coordination, Short-circuit Impedance, Short-circuit Forces, Loss evaluation, Temperature limits, Cooling, Sound Level .. etc. It will also explain overload and life expectancy of a transformer as well when Delta winding is needed in Wye-Wye connection. The presentation will answer why in North America we like to regulate from low voltage side whereas in Europe regulates from high voltage side.

Part 2:
Title: Transformer Manufacturing Processes

Abstract:
The presentation will be on the Industry wide manufacturing process to build a transformer in the shop floor. Processes will cover Core Construction, Insulation, Windings, Core and Coil, Processing, Tanking, Testing and Shipping. Some of the hold-points during the processes will be explained as well what a customer should look into while doing factory inspection. The presentation will also cover reconnection both in LV and HV, LTC Tap changer both in tank and separate tank, Lead works.

Part 3:
Title: Preparation of Transformer Specification

Abstract:
The purpose of this presentation/tutorial 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.
