Transformer Principles & Fundamentals
Mark Rivers, Vice President, Client Services;
Doble Engineering Company
As we move forward into the 21st Century, the use of electricity by mankind has evolved into a necessary staple of everyday life. But it
wasn’t always this way. The advent of power transformers in today’s world is a function of necessity, a product of ingenuity, and a marvel
of technology. Power transformers are the key element in the present system of electrical power distribution, and this system could not
function without transformers. Let’s take a look at why and how they were developed.
Mark Rivers received his BS in Electrical Engineering from the University of Massachusetts at Amherst, Massachusetts in 1979 and a
MBA at Nichols College in Dudley, Massachusetts in 1990. Since 1979 he had been employed by at Doble Engineering Company as a

Transformer Specifications
Don Platts, Customer Technical Executive;
SPX Transformer Solutions, Inc.
Since interpretation of the written word can be subjective, we will discuss some key elements of the transformer specification that are
critical to providing a complete quotation which results in satisfying both the customer’s wants and needs. This will be a comprehensive
look at the interpretation processes followed by most power transformers manufacturers as they design a transformer in response to a
client’s specification. The goal is to provide a clear, well-defined specification that eliminates variances of interpretation by vendors and
results in a proposal and product that meets the customers’ intentions and specifications. Many specifications refer to IEEE Standards for
definition, it is critical to know what the current revision of these standards require.
Donald Platts (“Don”) holds a BSEE degree from Lafayette College, Easton PA. He recently joined SPX Transformer Solutions as the

Transformer Economics - Evaluating Life-Cycle Ownership Costs
Jim McIver, Principal Applications Engineer;
Siemens Energy, Inc.
Purchase of a power transformer can easily account for the majority of investment into a new transmission or distribution substation. As
users strive for the most effective investment, it is important to consider life-cycle owning costs, rather than only the purchase price. It is
important for transformer owners to anticipate the many ways that transformer design is impacted by loss considerations. Different system
applications can lead to changing loss evaluation considerations, so it is important for the owner to choose an evaluation process that
properly reflects his financial, operational and quality needs.
Jim McIver has 38 years experience in the North American electric power industry. Prior to Siemens' acquisition of VA Tech, he was VA
Tech's Technology Director and now serves as Principal Application Engineer. While at Nevada Power, he managed design, procurement

Review of Geomagnetic Disturbances & the Impact on Power Transformers
Kiran Vedante, Consulting Research & Development Engineer;
ABB
There is some misconception in the electric power industry today that geo–magnetically induced currents (GIC) have caused, and would
cause, significant damage to the majority of large and medium power transformers installed on power grids in North America and around
the world. The purpose of this presentation is to present the true effect of GIC on power transformers. The presentation also provides
concise explanation of the cases of transformer failure / overheating reported in the published literature to have been caused by GIC
currents and demonstrates that, because of the nature of the GIC currents, the great majority of power transformers would not experience
much overheating or damage due to even high levels of GIC. Only some specific transformers could suffer some winding damage due to
high winding circulating currents if exposed to high levels of GIC. The real issue with GIC; namely, the narrow pulse of the magnetizing
current which results from part – cycle, semi – saturation of transformer cores when subjected to high levels of GIC currents will also be
addressed. This one current pulse / cycle could cause relays and capacitive components in power systems, such as SVC (s), to trip, which
may contribute to grid instability. Also, the current pulse is associated with 2nd and higher order harmonics. As a result, resonance may
occur, differential relays may operate, and stability of the grid may be compromised.
Kiran B. Vedante (SM-IEEE’2006) is presently a Consulting Research & Development Engineer at the Power Transformer Division of ABB
Inc. located in St. Louis, Missouri. He completed his Bachelor of Engineering, and Master of Engineering degrees in Electrical Engineering

Recent earthquakes throughout the world have highlighted the risk of damage to substation equipment. In addition to this, events such as
the Virginia earthquake have reminded asset owners that the potential for a seismic event is not limited to the west coast. Requirements
for the seismic qualification of transformers and their components has long been standard for utilities in areas with high seismic activity but
are now becoming more prevalent in less prone areas. The standards and methods used to seismically analyze transformers and their
components are constantly evolving and being reviewed by manufacturers, utilities, and asset owners. This presentation will address
methods for specifying seismic requirements, increased scrutiny that manufactures should expect for seismic qualifications of transformers,
recent changes in seismic qualification requirements, and seismic strengthening techniques for transformer designs.

Core-form vs. Shell-form Transformer Design & Construction
Juan Luis Thierry, Senior Transformer Consulting Engineer;
Doble Engineering Company
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.

Autotransformers for Electric Power Systems – Design and Construction Challenges
Enrique Bettancourt, Technology Planning Manager;
PROLEC GE
Electric autotransformers are key components in HV and EHV transmission networks. Their design and construction requires
application of advanced tools, to mitigate high voltage oscillations among closely coupled windings, and because high short
circuit currents frequently bring performance of materials and components close to their technical limits. Among others, tertiary
and stabilizing windings, application of internal voltage arresters and current limiting reactors are subjects frequently
addressed in specifications and design reviews. Testing of autotransformers implies special capabilities and equipment,
besides a clear specification and understanding of special operating conditions. All of these topics will be addressed in this
session.

HV and UHV long transmission lines present a capacitance to earth. These capacitive currents cause a voltage increase at
the end of the line, mainly if the load is low, which may be unacceptable. A primary application of “Shunt Reactors” is to
compensate these capacitive currents. In this session, we will present the main types of reactors and to explain the design
and manufacturing details of shunt reactors.

Between the years of 2002 and 2003, Southern California Edison (SCE) experienced several 500/220 kV transformer fires in
three of its 500kV substations. Without a fire mitigation system in place, the fires spread rapidly and resulted in tens of millions
of dollars of damage. SCE came to the realization that a Transformer Fire Mitigation System needed to be developed and
implemented to reduce potential future losses, minimize service disruption and reduce environmental damage. This
presentation will address the history and design of SCE’s 500kV transformer bank fire mitigation system and a case study of a
500kV transformer explosion and resulting fire.

As transformers grow in size and characteristics the overall management of these units within the fleet becomes more of a
challenge. From transportation options to sparing solutions, large power transformers can create headaches. If a transformer
can be broken apart in to more manageable pieces, then the options for fleet management increase considerably. Would you
rather ship with a standard flat bed rail car or a Schnabel car? Would you rather have a single spare for each transformer in
your fleet or one spare for numerous transformers? At least one option exists that answers these two questions and was
applied to a 700MVA; 230kV GSU. Come see the results.

This introductory presentation will provide an overview of pumps, coolers, fans, unit uprating, US and International standards,
ancillary and auxiliary systems, thermal constraints, ambient conditions, loading, dynamic modeling, design limitations, leak
repairs, and maintenance.
Losses in transformers are inevitable. Electromagnetic losses reflect as heat and consequently as elevated temperatures due
to thermal resistance. High temperature accelerates aging of insulation paper; the Arrhenius equation shows that the life of a
transformer is reduced by a factor of two with 8ºC rise in temperature. The transformer dissipates heat through all three
modes of heat transfer mechanisms - conduction, convection and radiation. The predominant mode of cooling is convection.
Both radiators and coolers depend primarily on convection for heat dissipation. When is one preferred over the other? So how
is the temperature controlled in new transformers with environmentally more friendly oils that are more viscous?
The second part of the presentation will address cooling system maintenance. With temperature control being crucial in newer
transformers, heat dissipation becomes very important. However, cooling system performance, with or without moving
mechanical equipment, deteriorates with age. Even systems without oil-pumps or fans can fail due to weathering, rusting and
fouling. How do we evaluate the health of the cooling system? Technology has improved with time, so what optimized
solutions are available?

Kurt Schamburg – Transformer Program Manager;
Calpine Corporation
Transformers represent one of the largest, most critical investments in an electric power system. Many utilities, generating
plants and industrials have large fleets of critical transformers and are looking for strategies to help identify units at risk of
failure so that limited maintenance resources can be focused where needed most. Whether evaluating an individual
transformer or a fleet, reliability assessments are complex and require a proven methodology and an experienced team of
design engineers, chemists and technicians using numerous evaluation criteria including DGA and oil analysis data, electrical
field test data, design and factory test data, operations and loading history, fault and short circuit history, maintenance and
repair history and any existing infrared and/or RFI survey data. Learn more about Doble’s two-stage approach with the intent
of consolidating all sources of transformer asset health information into an integrated view.
In 2011, Calpine Operating Services Company, Inc. initiated a transformer fleet management program at their approximately
100 power plants across North America. Calpine had standardized on a common routine laboratory diagnostics program and
electrical testing program for all their power plants. The next step was to perform an overall transformer fleet health
assessment so that Calpine could prioritize and focus operations and maintenance budgets towards transformer showing
significant indication of performance and reliability risk. Learn more about the key drivers behind their program, approaches
taken, early success and next steps in their comprehensive program.

Transformer life depends mainly on the condition of the liquid & solid insulation. The liquid insulation can be maintained and
restored with purification & reclamation. The solid insulation however is difficult to maintain directly. Various technologies and
techniques are available to maintain the insulation (both directly & indirectly). Appropriate selection and application of
transformer dry-out technologies and techniques can extend transformer life, reduce downtime and save money. These
technologies and their field applications will be discussed during this presentation.

Transformer Regasketing & Field Repair
Pierre Feghali, Project Management Specialist;
North American Sub-Station Services, LLC.
As the US transformer fleet ages, users are scrambling to replace their old transformers in record numbers. The large number
of transformers in service is making it difficult for users to reduce the average age of transformers from the extremely high
average of 40 years. Users are faced with the dilemma of not being able to replace transformers fast enough while the aging
fleet is leaking and starring imminent failure in the face. An alternative to replacement, is regasketing and field repair. This will
enable users to increase the life of their transformers until such a time that they make it to the top of the replacement list. The
other issue is the high e cost and lead-time for new transformers makes the alternative approach of reagsketing and repairing
the existing substation assets more attractive. This presentation will review some of the transformer regasketing and repair
projects and offer four real life examples of field regasket and repairs of transformers which were approaching end of life. The
repair enables the user to increase the transformer life and reduce the associated operating costs. This has allowed users to
delay the replacement by as much as 20 years.

Large power transformers are critical in today’s energy supply. The failure of a single unit could lead to a dramatic interruption
in the electrical grid. For this reason, there are many topics in the field of ensuring the proper condition of such transformers
currently available. With 70% of all transformers in the United States 25 years or older, and an average transformer life
expectancy of 40 years, aging of large power transformers is an area of important concern. In addition to aging transformers,
manufacturers are also faced with higher energy demands. One way of minimizing transformer failure and addressing higher
load issues is managing transformer capacity using advanced cooling systems. There are several controllable cooling
solutions which differ in range of application, degree of adjustment and certainly investment. This presentation addresses the
impact of changed transformer requirements (e.g. operational life span; transformer uprate; different installation site) on the
applicable cooling technology.

Partial Discharge – Detection, Location and Continuous Monitoring
Falk Werner, Sr. Field Engineer;
Doble Engineering Company
Over the past 30 years, great strides have been made in online monitoring and health assessment of transformers, rotating
machines and HV apparatus. Specifically, partial discharge (PD) measurements and monitoring offer excellent methods of
assessing the condition of various HV components under actual in-service stress such as load and temperature. With these
advances and a greater understanding of the mechanism of PD, a more informed decision can be made about the condition of
their associated insulation systems. These advances include better digital acquisition systems, noise rejection methods,
sensor technology and in particular advanced approaches in analysis and interpretation. This presentation will focus on the
mechanisms of partial discharge in HV apparatus, in particular in transformers, and analysis and interpretation for health
assessment of a transformer covering factory testing and in on-line service applications.
Falk Werner studied Electronics and Information Technology with a focus on Telecommunication and Signal Processing at the
University of Stuttgart, in Germany. His final thesis was entitled “Location of Partial Discharges by Means of Sensor Arrays.”





Key elements, from an insurer perspective, of risk mitigation plans including established maintenance practices to
“expert” monitoring systems.
IEEE currently has two approved guides for transformer and shunt reactor failure investigation and reporting:
C57.125-1991 Guide for Failure Investigation, Documentation, and Analysis and C57.117-1986 Guide for Reporting
Failure Data. An effort is underway to revise and consolidate the two existing guides. We will discuss the content of
new IEEE document, which is intended to encourage the establishment of routine and uniform data collection
procedures, establish consistency and compatibility with similar efforts by other organizations, and promote
cooperative efforts by users and manufacturers during the failure analysis.
Forensic examinations of transformers are conducted for a number of reasons; however, the end goal is typically to
determine the root cause of 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.
The life of a transformer is limited to the life of the insulation (cellulose paper and pressboard) inside the tank.
Natural or accelerated aging of the insulation can reduce chemical, mechanical, and dielectric strength of the paper
or pressboard which may lead to a catastrophic failure. Some of transformer failures are not due to old age, but

Transformer Induced Voltage Testing in the Field
John Herron, P.E., Sales Engineer;
HIGHVOLT
Gilbert Lemos, Supervisor;
Southern California Edison
Southern California Edison has been proactively replacing old and unreliable extra high voltage (EHV) transformers within our
service territory over the past several years. All new transformers are now coming from manufacturers based overseas.
Consequently, these transformers are more susceptible to damage caused by extra handling, including on and off-loading at
docks, traveling over-seas, railcar or truck, and off-loading at final destination. At any point along the way, this handling
exposes transformers to possible damage. In addition, the introduction of conductive contamination is possible during
disassembly at the factory or assembly at the final destination. As a result, this damage or contamination may not be detected
through internal inspection or routine acceptance testing. Since 2006, Southern California Edison has implemented field
induced testing with partial discharge (PD) measuring equipment as a final check to ensure the integrity of the transformer
before placing in service. Driving factors (cost and risks) which lead SCE to perform this test in the field, including a few cases
which would have led to failures will be discussed during this presentation.
The issue of induced testing on site will also be addressed. Induced testing is rapidly becoming a requirement and routine
diagnostic practice for power transformers. Reasons for performing this test and information that can be gleaned from test
results will be examined. Testing methods and available equipment technology will be discussed and compared. Also
presented will be an overview of revisions and updates to standards which are addressing this issue; IEEE C57.152 Field Test
Guide and associated IEC Standards..

Infrared thermography is a remarkable tool for inspecting electrical systems. However, it is just one tool in the tool box. When
properly used, thermal imaging cameras reveal thermal patterns that can both validate normal equipment operation and
forecast abnormal situations that can shorten the “Life of a Transformer”. Modern infrared cameras are reliable and easy to
use. Unfortunately the interpretation of images is more complex and an understanding of the technology’s limitations is crucial
for successful data analysis. This session focuses on the application of thermography on transformers and inspection
techniques. Real-life sample images will be shared demonstrating failure modes and infrared camera performance
specifications and inspection methodologies and reporting options will be discussed.

Reliable transformer operation can be significantly improved through the judicious application of electrical controls and
monitoring devices. Operating temperature, combustible gas generation, and tank pressure are several of the operating
parameters that provide an indication of a transformer’s condition. The instruments for control and monitoring these
parameters, the principles of their operation, and how they are effectively applied to power transformers will be presented.

Tap Changer Controls & Contribution to Premature Transformer Failures
Tom Jauch, Consultant;
Beckwith Electric Company
This presentation focuses on traditional Load Tap Changer (LTC) transformer control practices and those associated with
proposed SMART GRID (SG) functions. The use of LTC control capability for peer-peer communication and its effect on
transformer paralleling and in SG communication will be included. Also discussed will be transformer control practices which
may cause tapchanger hunting and therefore excessive tapchange operations. Applications of various paralleling methods and
the determination and confirmation of optimum settings, will be included.

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.
