Alabama Electrical 30 PDH Discount Package 3

This online engineering PDH course presents details cover issues related to DC fault calculation, DC protection equipment and DC arc flash energy calculation.

 

IEEE 1584 standard does not discuss arc flash hazard calculations in the DC systems. Standard NFPA-70E- 2000 provides a short calculation method. Therefore, the current literature is lacking calculations of arc flash hazard in DC systems. The necessary calculation steps are very similar to calculations in AC systems, however there are marked differences, particularly with respect to protection, cause of short-circuit currents in the DC electrical systems, and the current interruption devices in DC systems, which function fast to limit the energy let-through.

 

This 3 PDH online course is suitable for electrical engineers with a desire to understand DC system fault calculation followed by DC system arc flash calculation. Upon successful completion engineers will be able to address DC system fault calculation methodologies, basics of the DC protection equipment and methods to calculate incident energy in DC systems.

This online engineering PDH course provides a basic introduction to AC theory. The text is arranged to let you progress at your own pace, and concepts and terms are introduced as you need them, with many detailed examples and illustrations.

 

An alternating current (AC) is an electrical current whose magnitude and direction vary cyclically, as opposed to direct current, whose direction remains constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy.

 

Like DC, with AC circuits, power is equal to volts x amps, but this is only true instantaneously. Thus the power at any one moment in time is equal to the Volts at that time multiplied by the Amps at that time. If we want to find the average power used, we must take the average of the power at each time interval. Mathematically this is known as Integration. The integral of a sinusoid over one full period is zero, because there is as much time spent below zero as above it.

 

This 3 PDH online course is intended for professionals as well as individuals who are just beginning a career in electrical work, or who require a basic knowledge of electrical principals and equipment to better their primary responsibilities. This course is also a prerequisite for the all other electrical training.

This online engineering PDH course provides rules for time/current relay grading, IDMT protection characteristics, protection relay connections, as well as directional and ground protection.

 

Relay protection against high current was the earliest relay protection mechanism to develop. From this basic method, the graded overcurrent relay protection system, a discriminative short circuit protection, has been formulated. This should not be mixed with ‘overload’ relay protection, which typically utilizes relays that function in a time related in some degree to the thermal capacity of the equipment to be protected.

 

This 5 PDH online course is suitable for engineers with a desire to understand overcurrent protection fundamentals.

This online engineering PDH course provides a brief overview of the basic principles on which modern sensor technology functions. In describing modern sensor devices, we will need to also incorporate the basic concepts of physical measurement and the use of measurement instrumentation.

 

In examining the basics principles of sensor operation, we will cover some of the fundamental effects, physical phenomena, laws and rules of physics which are used by sensors to measure and quantify.

 

Though much of the modern sensor technology are based on MEMS (micro electro-mechanical systems), many of the same physical mechanisms which had allowed analog sensors in the past to operate, are still being used today in these micro “devices and machines”.

 

This 5 PDH online course is applicable to electrical and instrumentation engineers and other technical personnel who are interested in gaining a basic understanding of modern sensor technology.

This online engineering PDH course introduces the reader to the National Electric Code (NEC) and some of its mainstream tenets, as well as articles of the code that find common applications in electrical power distribution design. It also informs the reader about the legal and regulatory weight of the code; the fact that it's not just a voluntary standard. Readers are advised on how to enhance their knowledge of the code and why interpretation of the more profound aspects and interpretation of the code should be conducted by experienced electrical engineers.

 

Three common types of electrical drawings are discussed. These include a one-line power distribution schematic, a wiring diagram, and electrical control drawings.  The objective of this segment is to inculcate basic understanding of electrical symbols, electrical drawing conventions, and electrical design strategy. In addition, the reader will be provided a brief introduction to PLC Relay Ladder Logic Programming. Further, the reader is introduced to common industrial and commercial electrical power rate schedules. A few "low hanging fruit" type electrical energy cost savings opportunities are explored.

 

Finally, fundamental principles and concepts of illumination are introduced. Basic metrics associated with illumination and essentials of lighting system design are covered. Basic computational methods and illumination analysis associated with lighting system design are presented.

 

This 11 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 provides an overview of various types of indicating instruments used in engineering plants and other day-to-day applications.

 

Engineering measuring instruments are typically classified into the following groups: pressure gauges, temperature detectors, temperature measuring devices, electrical indicating instruments, liquid-level indicators, revolution counters and indicators, salinity indicators, and torque wrenches.

 

These instruments are used to determine how the engineering plant is operating. Machinery damage, personnel injury, and expensive and time-consuming repairs can be avoided by taking proper operator actions, which can only take place when the instruments (temperature indicators, pressure gauges, and so forth) are properly calibrated and properly interpreted by the operating personnel.

 

This 2 PDH online course is applicable to electrical and mechanical engineers as well as others interested in learning more about the basic instruments used in various engineering applications.
