Issue #28 - ARCAD website redesigned and revamped
After much hard work, we are pleased to introduce a
completely redesigned ARCAD website at www.arcadvisor.com.
Please take a few moments to navigate through the
updated website. We hope you enjoy the new design and
you'll find time to look through the many pages of
information waiting for you behind the new home page.
Please feel free to let us know about any suggestions
you might have or additional material you would like to
see on the website.
We have also recently released new Short Circuit Analytic (SCA) mobile app. The app takes into consideration all of the key electrical parameters of power distribution system including power supply, cables, transformers, motors, generators and performs available short circuit 3-phase and phase to phase fault current calculations in three-phase radial electric power systems. Visit the SCA mobile product page online at http://www.arcadvisor.com/
Did you know that most fabrics recommended for protection against electric arc fires will burn vigorously when exposed to a sufficiently large and sustained exposure fire? NFPA 70E allows flammable clothing with a fabric weight at least 4.5 oz/yd2 to be worn when working on tasks stated low risk. Stating a task as low risk and allowing the use of apparel fabrics may lead to severe injuries and fatalities from clothing ignitions in arc flash incidents. A method predicting the behavior of the fabrics during convective and radiant heating has been developed, and an article describing the method was recently published in the International Association of Electrical Inspectors (IAEI) magazine.

Issue #27 - Ignition and Melting Characteristics of Protective Clothing
Wishing you a Happy Easter! I hope some time out for rest and
relaxation with your loved ones puts a spring in your step and gives
you a chance to celebrate life and all its blessings. Peace, love,
joy and yummy Easter eggs to you!
Here at ARCAD INC., we would also like to express to you our sincere appreciation for your loyalty and take this opportunity to update you on arc flash news and ARCAD INC. solutions addressing the matter.
HOW TO EVALUATE THRESHOLD INCIDENT ENERGY FOR IGNITION OR MELTING OF PROTECTIVE CLOTHING
In many cases, if exposed to a sufficiently large and sustained exposure fire, the fire-retardant (FR) fabrics will burn vigorously. Fabric's time to ignition or melting versus heat flux data can be used for determining the textile TDU value. For example, Figure 1 shows that it takes approximately 5cal/cm2/sec heat flux for igniting denim textile listed in Table 1 within 3 seconds time interval. The TDU value for the denim fabric can be calculated by substituting the values for heat flux and time to ignition into Equation 4, and it is roughly equal to 3800(kW/m2)4/3 * sec. Behavior of the fabrics other than those listed in Table 1 during convective and radiant heating can be predicted using a simple test that can be quite easily reproduced in the field.

"The 2015 edition of nfpa 70e no longer has a PPE Category 0, however my software still calculates Level 0. What am I missing?"
Indeed, the AFA V5.0 software does not show anywhere the term "PPE Category" or "Hazard Risk Category" (HRC). The program displays term "Level". The new NFPA 70E 2015 does not prohibit using the term "Level". As long as you don't call it "PPE Category" there should be nothing preventing you from doing so. Remember that not that long ago people were told not to mix HRC with incident energy. So they began to call it 1, 2, 3 and 4 PPE categories to get away from the term HRC. This time around the NFPA 70E claimed ownership for the term "PPE category" that people moved to, and say you can't use that term with incident energy. Also, the NFPA Handbook shows a sample label with fields to be filled in for "Available Incident Energy" and "Level of PPE" while just half a page earlier states that "available incident energy" cannot be included with the "PPE category" in table 130.7(C)15(A)(b). It makes sense since the "Level of PPE" and "PPE Category" are technically two different terms.
Clicking on Settings menu, selecting Incident Energy at AFB and switching to Evaluated option will also prevent the Level 0 displayed on arc flash labels created using the AFA V5.0 program. Also, you can edit default site-specific PPE by clicking on Settings menu, selecting Site Specific PPE and making required changes.
MODELLING HRC FUSES FOR ARC FLASH ANALYSIS
IEEE 1584 Guide for Performing Arc Flash Calculations has established practice when modelling HRC fuses for arc flash analysis. The IEEE 1584 4.6 Step 5 reads "For fuses, the manufacturer's time-current curves may include both melting and clearing time. If so, use the clearing time. If they show only the average melt time, add to that time 15%, up to 0.03 seconds, and 10% above 0.03 seconds to determine total clearing time. If the arcing fault current is above the total clearing time at the bottom of the curve (0.01 seconds), use 0.01 seconds for the time". The opening time tolerances differ between fuse designs and the percentage of the overload relative to the amp rating. Incrementing the time according to IEEE 1584 guidelines should effectively compensate for the margin of error in published time-current curves in most cases.

Issue #26 - Behavior of Apparel Fabrics during Convective and Radiant Heating
This week is March Break in Canada. Springtime around the world is traditionally observed as a time of renewal. we hope you have an opportunity to engage in some needed spring cleaning such as catching up on some long-delayed project or chore at work or at home, or simply taking a few moments to take stock of your goals. However you plan to spend spring break, we wish you an enjoyable time and an opportunity to focus on yourself, family and friends. We would also like to take this opportunity to update you on arc flash news and ARCAD INC. solutions addressing the matter.
BEHAVIOR OF APPAREL FABRICS DURING CONVECTIVE AND RADIANT HEATING
Personal protective equipment (PPE) recommended for arc flash is not always designed for arc flash exposure. The purpose of this paper and accompanying online calculator is to warn of the dangers posed by using the improper materials in arc flash exposures until standards have caught up on this issue. NFPA 70E allows flammable clothing with a fabric weight at least 4.5 oz/yd^2 ( > 0.16kg/m^2) to be worn when working on tasks stated low risk. Stating a task as low risk and allowing the use of apparel fabrics may lead to severe injuries and fatalities from clothing ignitions in arc flash incidents. The NFPA 70E based arc flash analysis fails to consider the variable nature of onset to second degree burn energy on bare skin. Also, there seem to be issues in NFPA 70E when the standard calculation procedure for determining arc flash boundaries allowing flammable clothing to be worn in situations that could result in ignition of the clothing.

IEEE 1584 FUSE EQUATIONS
IEEE 1584-2002 provides formulae for calculating arc-flash energies for use with current-limiting Class L and Class RK1 fuses. What is the manufacturer of the fuses used to develop the formulas in IEEE 1584? Do the formulas apply for 440V 50Hz? Check the link below for answers to these and more fuse related questions:

NEW GRAPHICS PER THE 2015 NFPA 70E
In the past, the images that include the prohibited approach boundary were used for arc flash labeling. Since the NFPA has discontinued use of the prohibited approach boundary definition, it is recommended to bring arc flash hazard labels up to date with the terminology in the standard. Check the link below for an example of image with only the limited and restricted approach boundaries along with the arc flash boundary shown and accompanying discussion:

- Nominal system voltage for shock hazard assessment has been revised reflecting changes to NFPA 70E table 130.4(c)(a)
- All references to the prohibited approach boundary have been deleted throughout the standard and the AFA V5.0 program. Once the restricted approach boundary was crossed, there were no other requirements in the NFPA 70E 2015 edition.
- All label layouts and terminology have been rearranged to meet the new standard requirements.
- Personal protective equipment (PPE) recommendations displayed on labels created using the program can be reviewed, edited or reset to default values. The feature will let you making necessarily PPE adjustments required for various tasks in English and a variety of other languages. Also, the PPE requirements in new NFPA 70E standard have changed from previous editions of the standard. They may become different again and the feature will let you make changes as the safety standard evolves without the need to purchase new program.
- The program is now memorizing selected label style (including label size, text color, style), optional extra line title, value etc.
