Wednesday: Morning Technical Seminars


8:00 AM
A Comprehensive Strategy for Low and Medium Voltage Cable Fault Location

Speaker: Thomas Sandri, Shermco Industries

Description:
The mere mention of cable fault location sends shivers down many a spine. Don’t lose heart, all is not lost. Remember, cable fault location, like any other craft, simply requires some basic skills, proper tools and a sound procedure. Don’t be fooled into over simplifying the problem or solely relying on a single technique or instrument for every situation.

Although many faults exhibit similar properties, all faults are unique and therefore different. A fault locating technique or instrument that works well in one situation may be completely useless in another.

In this seminar we will review cable fault locating techniques, their strengths and weaknesses and build a comprehensive strategy for fault location on both low and medium voltage cables.

How Smart Workers Use Situational Awareness to Improve Safety

Speakers: Richard Gasaway, Situational Awareness Matters

Description:
Most workers know, intuitively, that strong situational awareness is an important aspect of worksite safety. However, many do not understand what situational awareness is, how it is developed and how it can erode while working in a high risk, high consequence environment.

Participants will learn:
-3-step process for developing and maintaining situational awareness while working in high-risk environments.
-7 ways stress impacts performance and a proven 4-step process to combat the effects of stress on decision making.
-10 best practices for overcoming the “Dirty-Dozen” situational awareness barriers.
-5 tricks to use during training evolutions that will help members improve decision making skills.
-7 immediately-actionable skills to improve critical thinking and resilient problem solving. 

We’ll answer important questions, like:
1. What exactly is situational awareness?
2. Why is situational awareness important to worker safety?
3. How is situational awareness developed and maintained?
4. Why is situational awareness so difficult to develop and maintain in high-risk work environments?
5. What tips and best practices improve situational awareness in the workplace?

8:00 AM
Transformers Winding Condition Assessment

Speakers: Daniel Carreno and Sameer Kulkarni, Megger

Description:

The transformer windings are amongst the main components to maintain to ensure proper functionality and reliability of the system. Among the most important tests to assess the transformer winding’s condition are Transformer Turns Ratio (TTR), Windings Resistance (WR) and Excitation Current measurements. There is a strong correlation between these three measurements, as in conjunction they can detect windings related issues, such as improper number of turns, turn-to-turn insulation failure, internal connection problems -- including those to the tap changers (if installed) -- as well as shorted laminations in the core, ground faults, residual magnetism, and core structure deficiencies.

Join us for this Best Practices Seminar to learn more about the theory of these important diagnostic tools, as well as the tools and analysis criteria that can help you assess the condition of the transformer windings.
