Arc Flash Hazard Calculations in DC Systems (E03-035)
Basic Concepts of Alternating Current (E03-003)
Introduction to Protective Device Coordination Analysis (E04-030)
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 PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the DC system fault calculation methodology
- Learning about short circuit current calculation of DC elements such as batteries and rectifiers
- Learning about DC circuit breakers and fuses
- Knowing how to calculate incident energy in DC systems
- Learning about the protection of semiconductor devices
Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty (20) questions to earn 3 PDH credits.
Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you will be able to print it after we receive your payment.) For your convenience, we will also email it to you. Please note that you can log in to your account at any time to access and print your Certificate of Completion.
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 PE continuing education course is intended to provide you with the following specific knowledge and skills:
- The differences between AC and DC voltage and current
- The advantages of AC power transmission over DC power transmission
- The "left-hand rule" for a conductor
- The relationship between current and magnetism
- The methods by which AC power can be generated
- The relationship between frequency, period, time, and wavelength
- Peak-to-peak, instantaneous, effective, and average values of voltage and current
- The phase difference between sine waves
In this professional engineering CEU course, you need to review Chapter 1 of Module 2 titled "Introduction to Alternating Current and Transformers" of the Naval Education and Training Materials (NAVEDTRA 14173), Electricity and Electronic Training Series.

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 PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the basic theory behind protective device coordination studies
- Understanding how overcurrent and earth fault protection device coordination is achieved
- Learning about commercial software modelling techniques, simulation performance and interpretation of the results
In this professional engineering CEU course, you need to review the document titled, "Introduction to Protective Device Coordination Analysis".
Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty five (25) questions to earn 4 PDH credits. The quiz will be based on the entire document.
