Delaware Electrical and Ethics 24 PDH Discount Package 2

This online engineering PDH course describes the basic concept, function, types, and the different components of electrical transformers.  

A transformer is an electrical equipment that transfers energy from one circuit to another by electromagnetic induction. They are often used to convert between high and low voltages (step-up or step down). Transformers and their components vary depending on the application and are available in several different configurations.  

This online engineering PDH course introduces the reader to the concept of load factor, its role in power quality considerations and electrical energy cost reduction through peak shaving. Significance of electrical equipment service factor and voltage regulation of power distribution systems is highlighted. Electric power bill calculation in residential, commercial and industrial arena is illustrated.

DC and AC motors and generators are introduced. Basic principles and equations governing the operation and performance of electric motors are presented. Common calculations involving electric motors are covered, and illustrated through examples and self-assessment problems. The reader is introduced to the concepts of induction motor slip and the roles that slip and frequency play in determination of the motor shaft speed.

An exploratory tour of power distribution and safety equipment is conducted through the review of motor control center (MCC), power switchgear, electronic safety devices and variable frequency drives (VFD). Pictures and diagrams are used in this discussion to give the reader a "hands- on" feel of common electrical and electronic equipment.

This 8 PDH online course is applicable to engineers of all disciplines, as well as technicians, facilities managers and executives who are not intimately familiar with electrical engineering principles and practices.

This online engineering PDH course describes electrical measuring devices such as voltmeters, ammeters, ohmmeters and wattmeters. It also describes test equipment such as multimeters and meggers. It discusses the electrical parameters measured and the principles of operation of common instruments.

This 2 PDH  online course is applicable to electrical and computer engineers, design and construction personnel, technical staff and facility operators who are interested in gaining a better understanding of electrical test instruments and measuring devices.

This online engineering PDH course describes the hazards of electrical work and basic approaches to working safely.

Whenever working with power tools or on electrical circuits, there is a risk of electrical hazards, especially electrical shock. Anyone can be exposed to these hazards at home or at work. Workers are exposed to more hazards because job sites can be cluttered with tools and materials, fast-paced, and open to the weather. Risk is also higher at work because many jobs involve electric power tools.

Electrical trades workers must pay special attention to electrical hazards because they work on electrical circuits. Coming in contact with an electrical voltage can cause current to flow through the body, resulting in electrical shock and burns. Serious injury or even death may occur. As a source of energy, electricity is used without much thought about the hazards it can cause. Because electricity is a familiar part of our lives, it often is not treated with enough caution. As a result, an average of one worker is electrocuted on the job every day of every year! 

This online engieering PDH course provides instruction in engineering ethics through a case study of the Space Shuttle Challenger disaster. The minimum technical details needed to understand the physical cause of the Shuttle failure are presented. The disaster itself is chronicled through NASA photographs. Next the decision-making process, especially the discussions occurring during the teleconference held on the evening before the launch, is described. Direct quotations from engineers interviewed after the disaster are used to illustrate the ambiguities of the data and the pressures that the decision-makers faced in the months and hours preceding the launch. The course culminates in an extended treatment of six ethical issues raised by Challenger.

This 3 PDH online course is intended for all engineers who are interested in gaining a better understanding about the ethical issues that lead to the Challenger disaster and how they could have been avoided.
