Protecting Your Critical Assets – Transformers
Monday, April 8, 2019 | 9:00 AM – 12:00 PM | Marina 2 – 4, Lobby Level
Ed Khan; Doble Engineering Company
Transformers are critical assets that are very expensive so they need to be well protected. This three hour course is geared towards providing a complete description of the following protection schemes that are applied to transformers:
- Harmonic blocking/restraint
- Restricted earth fault protection
- Through fault protection
This training will describe in a simple and concise manner, the theory behind these protection schemes. These schemes need to be set appropriately to ensure that, when called upon, they will perform correctly and ensure the last line of defense works to minimize damage. The settings should also ensure that nuisance trips do not occur since they have a big impact on the reliability of the grid. In addition, we will describe the impacts of renewable power plants on transformers.
The intended audience for this training includes:
- Insurance personnel
Monday, April 8, 2019 | 9:00 AM – 10:30 AM | Commonwealth Ballroom, Concourse Level
Michelle Ward; Doble Engineering Company
DTAWeb is a powerful tool that allows the client safe secure storage of high voltage apparatus test results and associated documentation, including but not limited to Doble tests. DTAWeb includes asset management support functions, results data management and statistical analysis for bushing results.
This training will provide basic information on DTAWeb as well as exampled for test scheduling, data comparison to benchmarks, highlighting apparatus and sub-systems with poor test results and identifying apparatus based on industry service advisories.
The DTA User Group will follow immediately after this training in the same room.
Protecting Your Critical Assets – Generators & Motors
Generator & Motor Protection
Monday, April 8, 2019 | 1:00 PM – 5:30 PM | Marina 2 – 4, Lobby Level

Proper Application of Power Transformers, Autotransformers and the Tertiary Winding Transformer (Webinar)
Tuesday, April 9, 2019 | 9:30 AM – 11:30 AM | Commonwealth Ballroom, Concourse Level
Darin Mitton; Doble Engineering Company
Proper application of power transformers is essential for effective, reliable and economic operation. While some margin of extra capability may be desirable to accommodate planned upgrades or abnormal circumstances, too much can lead to excessive installation and operating costs. Insufficient capability can lead to increased maintenance and operating costs, and premature failure. For some applications, the auto connected transformer can offer economic benefits of lower material cost and reduced losses. But the galvanic connection limits isolation between the primary and secondary windings, making it unsuitable for many applications, and often necessitates inclusion of a tertiary winding. This two part discussion will include a review of the IEEE standard general requirements for power transformers and how they relate to the performance, design and cost of power transformers in general. Usual service conditions, unusual service conditions and operating at other than nameplate rating will be considered. The discussion on autotransformers will include basic concepts, such as co-ratio and the auto connection impact on impedance. Design considerations and construction features of the autotransformer will be presented. Operational considerations such as the need for a tertiary winding for harmonic currents, balancing or station loading will be reviewed.
This training is planned to be presented as a Webinar. Look for e-mail invitations.
Power Factor Theory
Tuesday, April 9, 2019 | 1:00 PM – 2:30 PM | Commonwealth Ballroom, Concourse Level
Jeff Short; Doble Engineering Company
This training will review dielectric theory and its role in power apparatus. The topic will define the information that is captured as part of the measurement, such as capacitance, watts and power factor, and the role of each in insulation assessment. The various test circuits used with the test set will be explained.
Transformer Testing Training
Tuesday, April 9, 2019 | 3:00 PM – 5:00 PM | Commonwealth Ballroom, Concourse Level
Mike Anderson; Doble Engineering Company
The training will discuss several transformer field test procedures used to determine the health and condition of various aspects of the transformer. Topics covered will include dielectric (power factor and capacitance) system testing, excitation current and losses, leakage reactance, and turns-ratio.
Wednesday, April 10, 2019 | 8:00 AM – 12:00 PM & 1:30 PM – 6:00 PM | Marina 4, Lobby Level
Geo-magnetically Induced Current Training
Wednesday, April 10, 2019 | 10:30 AM – 12:00 PM | Commonwealth Ballroom, Concourse Level
Dom Corsi; Doble Engineering Company
Severe geomagnetic disturbances (GMDs) caused by solar storms in upper atmospheric layers can induce currents in long conductors on the Earth’s surface, such as power lines, which can overload the electric grid system triggering voltage collapse, or worse, damage expensive extra-high voltage power transformers.
To adhere to the new NERC standard TPL-007-1, applicable entities must assess the potential impact of a benchmark GMD event on the bulk power system potentially including a transformer thermal impact assessment to ensure that all high-side, wye grounded transformers above 200kV can withstand the thermal transient effects associated with benchmark GMD event. This presentation will address:
- How geomagnetic disturbances can impact transformers
- New NERC standards to address geomagnetic disturbance events
- Transformer thermal impact assessment requirements and information required to complete a transformer thermal impact assessment
Power Factor Case Studies
Wednesday, April 10, 2019 | 1:30 PM – 2:45 PM | Commonwealth Ballroom, Concourse Level
Jeff Short; Doble Engineering Company
The presentation will build on the principles discussed during the Power Factor Theory and Transformer Testing Training sessions, by applying apply the theory and test methods discussed previously to real-world case studies. Through the review of test results, the topic will cover items to consider during testing, such as reasons for testing, impact of environmental conditions on measurements, typical test setup errors, grounding schemes, evaluation of expected vs. measured results, relationships between different transformer tests, and the impact of various fault conditions on apparatus measurements.
Swept Frequency Response Analysis (SFRA)
Wednesday, April 10, 2019 | 3:00 PM – 4:15 PM | Commonwealth Ballroom, Concourse Level
Linda Nowak; Doble Engineering Company
The training will discuss the role of frequency response analysis in a transformer condition assessment program. Included will be a review of theory, test procedures and expected results.

Circuit Breaker Fundamentals (Webinar)
Thursday, April 10, 2019 | 2:00 PM – 3:30 PM | Commonwealth Ballroom, Concourse Level
Mike Wolf; Doble Engineering Company
Circuit breakers are an integral component to the electric system and need to be tested routinely to confirm their performance. An understanding of the breaker’s construction is essential to properly identify and diagnose problems as they show themselves during testing. This presentation will review the operation, general design, and construction of oil, vacuum, and gas circuit breakers. Available diagnostic testing methods will be discussed, touching on the purpose, diagnostic significance, and benefit of each test. Throughout the presentation, real-world examples will be provided to better visualize the discussion.
