6:30 AM – 8:00 AM Attendee Breakfast
7:00 AM – 6:00 PM Registration & Information Desk Open
8:00 AM ‐ 8:30 AM Autotransformers
Waldemar Ziomek, Senior Global Expert ‐ Power Transformers & High Voltage Insulation
CG Global
When the primary and secondary voltages are obtained from the same winding, or from two windings which are
galvanically connected, such a transformer is called an autotransformer. The autotransformer requires less turns
than a two‐winding transformer. The presentation will focus on fundamentals, design and applications of
autotransformers. It will start with basic concept and typical winding arrangements. Next, the voltage variation will
be addressed through presentation of different tap winding arrangement in the unit. Magnetic field distributions and
resulting impedance at different tap positions will be shown. The selected problems of insulating system will be
discussed (e.g. end fed vs center fed HV lead bring out, stresses in the end insulation). Examples of the lightning
impulse voltage distributions for different winding arrangements will be shown.
Dr. Waldemar Ziomek works for CG Power Systems, as a global senior expert in the area of power transformers. Till
2013 he was employed by CG Power Systems Canada's large power transformer plant in Winnipeg, MB, as Manager

8:00 AM – 10:00 AM Asset Life‐Cycle Decision Making
The utility systems require a broad spectrum of equipment for the transmission of electric power from the utility
generating stations to distribution substations located near industrial plants and residential areas. Transformers are
used in most of the power systems, as generator step‐up transformers; as transmission autotransformers and as
shunt reactors. Mobile substations are used by utilities for emergency or temporary power sources. These units are
usually a transformer in a package with HV breaker, arresters and LV switchgear mounted on a trailer for easy
transport.
Power transformers are also used for special industrial application such as electric arc furnace transformers which
supply high current, low voltage power to arc furnaces used in steel making. The development and growth of the
transformer stemmed from a basic need for low cost electric power generation and transmission, and the question
has been always the same: core type or shell type? Both transformer types are suit for essentially the same
application, but there are some design features that can make the difference in the long run. The Purpose of this
presentation is to identify the main design and construction differences between core‐form and the shell‐form
transformers.
8:30 AM – 9:00 AM Mobile Transformers & Substations
Marion Jaroszewski, Senior Consultant
Delta Star, Inc.
Types and applications of mobile substations are presented. A mobile versus power transformer is discussed with
emphasis on the temperature ratings and associated with it hybrid insulation system, short circuit and dielectric strength,
oil preservation and cooling system design. The mobile transformer and substation testing is discussed. The essentials of
specifications and trailer components are also addressed.

Root Causes of Failures
Bill Griesacker, Transformer Consulting Engineer
Doble Engineering Company
Forensic examinations are conducted for a number of reasons; however, the end goal is
typically to determine the root cause of the failure. Often this examination involves the
review of historical operating conditions prior to the failure and the disassembly of the
failed transformer in search of supporting evidence. Case studies will be presented.
Bill Griesacker is a member of Doble Engineering Company as a transformer engineer working on projects that include factory inspections, condition assessment, design reviews, failure analysis and general consulting. Mr. Griesacker holds an MS in electric power engineering from the Rensselaer Polytechnic Institute and a BS in electrical engineering from Gannon University. He is an active member of the IEEE, PES Transformers Committee where he holds positions in several working groups and subcommittees.

6:00 AM – 4:00 PM Registration & Information Desk Open
7:00 AM – 4:00 PM Transformer Condition Assessment Using Laboratory Diagnostics
David Koehler, Manager Laboratory Services
Doble Engineering Company
This one‐day session provides students with a thorough understanding of how to assess the condition of electrical
insulating materials and transformers.
Dissolved gas‐in‐oil analysis – This is the single most important diagnostic test for transformers. This presentation
reviews how the test is performed, how to distinguish between normal gassing behavior and problems, and how to
evaluate trends. Practical case studies and examples are used to illustrate theoretical concepts. Seminar participants
will be quizzed (with class participation) on their understanding in diagnosing 12 cases.
Water in Transformer Oil – Assessing how dry a transformer is requires more than a water in oil test. Learn how to
assess the wetness of the transformer insulation system and why you need to know the operating temperature at
the time of sampling. This session discusses water migration in transformers and how water affects the ability to
overload them. Examples are provided.
Condition assessment of cellulosic insulation – The analysis of the condition of the paper insulation has changed
quite a bit in the past 10 years. Learn how the solid insulation ages and how to assess the condition of the paper and
pressboard insulation and its remaining life. Case studies are given to illustrate the distribution of paper aging in
transformers and how operation and maintenance can influence it.
Metals in oil – This presentation provides an understanding of the importance of metal‐in‐oil tests as a diagnostic.
To be able to use the information, the correct test must be specified – learn the difference between dissolved and
particulate metals and when to choose each test. Case studies are given.
Quality of new and service aged oils – Background information is provided on the properties of transformer oil. The
presentation includes how to specify and evaluate new oils, what tests to perform and how to evaluate in‐service
oils.
Aging characteristics of insulating materials ‐ Aging is discussed in sections on oil and paper which provides
information on how to increase the life of transformers. There are a number of factors that accelerate the aging of
the insulation system that can be controlled. This session provides information on when to reclaim or replace oil and
gives specifications for reclaimed oil.
Load tap changer and oil circuit breaker diagnostics – This presentation gives the latest information on diagnostics
for load tap changers (LTCs) and bulk oil breakers. Case studies are provided.
Sampling – The presentation discusses how to save money on your sampling program through proper training and
what common pitfalls to avoid. Proper sampling preparation, practices, and equipment are given.
