100 Level Courses: Prerequisites for all Advanced Courses

EIU101 - The Big Picture
Class 1 - T.E.A.M. Concept
Scope: The real world needs information about all aspects of an application. Individual tests are usually limited to one aspect. The real world can be approached by separating the multifactor requirements of the application into single-factor evaluation. The real world multifactor stresses can be approached as a T.E.A.M. concept: T = Thermal stresses; E = Electrical stresses; A = Ambient (environmental) stresses; and, M = Mechanical stresses. Testing is usually approached addressing one aspect of TEAM at a time and combining the results.
Class 2 - Spectrum of Testing
Scope: Each aspect of the total processes from selection of materials and manufacturing processes through to completion of the evaluation of an end-product can be separated into testing and evaluations at different levels. All of the various levels of tests can be structured into different categories while these categories are linked in some manner.
Class 3 - Structure of Standards
Scope: All standards start with the end-product requirement for safety and performance

EIU104 - Types of EIM
Class 1 - General Descriptions
Scope: This course introduces many of the wide range of categories of materials used in end-product manufacturing. Each category presented in presented to describe the type of material and some aspects of the selection process. Categories of materials include Wire and wire insulation; Insulating Varnishes / Impregnating Resins, Potting Compounds; Films / Sheet Insulation and their composites; Molding resins.

EIU105 - ELTEK Labs and UL
Class 1 - Levels of Interaction
Scope: This course presents an explanation of the long-term relationship which exist between Underwriters Laboratories [UL] and ELTEK International Laboratories [ELTEK Labs].

EIU106 - Thermal Classifications
Class 1 - General
Scope: This course presents a general introduction level to the structure of the thermal classes used for different categories of materials. There are two systems used for designation; one using numerical values and the second using letters. This course describes the international system used to define Thermal classes; when to use numerical designations vs. letter designations; how to use the thermal classifications for EIM and EIS vs. use for end-products

200 Level Courses:

EIU 200 - Electrical Insulation Materials (EIM)
Class 1
Scope: Presents the function of a material [component] selected for the manufacturing of an end product to serve as an EIM.
Class 2
Scope: What is the distinction between "major insulation" and "minor insulation"?
Class 3
Scope: Properties of EIM "as received"

EIU 201 - EIM Thermal Rating
Class 1
Scope: Why thermal ratings are the most common type of ratings assigned to EIM.
Class 2
Scope: Presents the distinction between Relative Thermal Index ratings [RTI] and Thermal Index ratings [TI]. Some EIM have TI values while other EIM have RTI values assigned.
Class 3
Scope: Presents a comparison of the two main thermal aging techniques

• [1] The traditional Fixed Temperature [FT]; and,
• [2] The Fixed Time Frame Methods [FTFM]; similarities and differences

EIU 210 - Electrical Insulation Systems (EIS)
Class 1 - Origins of EIS Testing
Scope: Presents the origin of the concept of EIS testing
Class 2
Scope: Presents an explanation of possible test specimens; what are the possible properties to be tested?
Class 3
Scope: EIS testing is intended to be an RTI type of program
Class 4
Scope: A summary of IEEE EIS test methods
Class 5
Scope: An explanation of the two general types of EIS [1] Open and [2] Encapsulated

EIU 211 - EIS Thermal Ratings
Scope: Different EIS test methods make reference to a “Control” or “Reference” EIS.

EIU 212 - EIS Calibration at ELTEK Labs
Scope: EIS

EIU 220 - Compatibility testing
Class 1 - Compatibility In General
Scope: Compatibility testing is application related. The link to the T.E.A.M. approach; different applications means different stresses, A = Ambient (environmental) stresses
Class 2
Scope: Compatibility testing of EIM
Class 3
Scope: Compatibility testing of EIS

Scope: Domestic and International flame tests and applications

EIU 310 - Allowable Magnet Wire Substitutions into Established EIS

EIU-333 - The Role of Fillers
Class 1 - Fillers in Casting or Potting Compounds
