Maine Electrical 30 PDH Discount Package 2

This online PDH course presents the basics of motor and drive systems and briefly describes important terms, relationships, and system design considerations. It also provides a roadmap for finding opportunities to improve motor performance, as well as exploring the economics of motor systems.

 

Electric motors, taken together, make up the single largest end use of electricity in the United States. In the U.S. manufacturing sector, electric motors used for machine drives such as pumps, conveyors, compressors, fans, mixers, grinders, and other materials handling or processing equipment account for about 54% of electricity consumption.

 

To achieve cost-effective operation and maintenance of a motor and drive system, operators must pay attention to the entire system as well as to its individual components. Often, when investigating efficiency opportunities, operators are so focused on the immediate demands of this equipment that they overlook the bigger picture, which includes the ways in which system parameters affect all the equipment.

 

This 6 PDH online course is intended for electrical and mechanical engineers, contractors, manufacturers, building professionals and others interested in learning more about improving motor and drive system performance.

This online engineering PDH course provides an introduction to protective device coordination analysis in a very structured fashion. First, a modelling technique is shown for a generic power system, protective relays are modelled in detail, and relay settings are determined based on short circuit current calculations. A detailed explanation of modelling and calculation procedures is offered. Illustrated techniques can be implemented in any commercial power system software package.

 

The objective of a protection scheme in a power system is to minimize hazards to personnel and equipment while allowing the least disruption of power service. Coordination studies are required to select or verify the clearing characteristics of devices such as fuses, circuit breakers, and relays used in the protection scheme. These studies are also needed to determine the protective device settings that will provide selective fault isolation. The goal is to achieve an optimum balance between equipment protection and selective fault isolation that is consistent with the operating requirements of the overall power system.

 

This 4 PDH online course is suitable for electrical engineers with a desire to learn about the analysis of protective device coordination.

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 5 PDH online course is applicable to electrical and mechanical engineers, maintenance personnel and other technical staff who are interested in gaining a better understanding of transformers.

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 presents details that address IEEE and IEC equipment accessibility types, arc resistant ratings, and testing procedures according to IEEE standards.

 

Arc flash resistant equipment may be described as the equipment made to withstand the impact of internal arcing fault by meeting the testing requirements of IEEE Guide C37.20.7-2007. In the 1970s, an interest started in Europe in assessing electrical equipment under internal arcing, which lead to IEC standard. This research spread to North America and was used as a foundation for EEMAC G14-1 procedure. The development of IEEE standard heavily relies on Annex AA of IEC standard and adopts many of the refinements originated in EEMAC G14-1 procedure. IEC 62271-200 defines the requirements for factory assembled metal-enclosed switchgear and control gear for alternating currents at rated voltage above 1 kV and up to and including 52 kV. It includes indoor and outdoor assemblies and frequencies up to and including 60 Hz.

This 2 PDH online course is suitable for electrical engineers with a desire to find out more about arc flash resistant equipment. Upon successful completion engineers will have more information about usage of arc flash resistant equipment and its proper application.

This online engineering PDH course provides a basic understanding of the fundamental principles, concepts and definitions of radar systems.

 

The term Radar is an acronym made up of the words radio detection and ranging. The term is used to refer to electronic equipment that detect the presence, direction, height, and distance of objects by using reflected electromagnetic energy.

 

Modern radar systems are used for early detection of surface or air objects and provide extremely accurate information on distance, direction, height, and speed of the objects. Radar is also used to guide missiles to targets and direct the firing of gun systems. Other types of radar provide long-distance surveillance and navigation information.

 

This 5 PDH online course is applicable to electrical, instrumentation and communication engineers, as well as other technical personnel interested in gaining a better understanding about radar principles.
