Harnessing Modern Software to Improve Arc Flash Safety
Anyone who works in facility safety should know that an arc flash has the potential to be one of the most dangerous, destructive and even deadly events that take place. To put it simply, an arc flash is any electrical discharge where the electricity travels through the air between two conductors or between one conductor and a ground.
The event is an electrical explosion that can result in fires, damage to equipment, serious injury or even death to those in the area. What makes an arc flash particularly dangerous is that they occur so quickly and often with no external warnings.
Dangers of an Arc Flash
While any type of electrical shock can be dangerous, an arc flash can really take it to the next level. This is because an arch flash can reach temperatures exceeding 35,000 degrees Fahrenheit. These extreme temperatures can instantly vaporize metal and create a splash of plasma or molten metal throughout the area.
If someone is working anywhere in between the source and destination of the electricity during an arc flash, the electricity can pass through them or close to them to cause severe burns. Another risk is that the arc flash force will throw the individual some distance, potentially causing a significant amount of harm. Of course, any resulting fires from the arc flash could also be quite deadly.
In addition to the extreme heat and other dangers, the arc flash can also be harmful due to direct electrocution of those in the area.
Most arc flashes occur in electrical systems that run at 480V or higher. The higher the voltage, the more risk there will be. With this in mind, all facilities should be taking all possible precautions to help minimize the risk of an arc flash occurring.
Modern Options for Reducing Arc Flash Risk
Over the years there have been many safety improvements when it comes to electrical equipment. Using proper personal protection equipment, checking wiring for proper insulation and things like this have all helped to contribute to the overall safety of many facilities. While important, these are very manual tasks that can only provide a limited amount of benefit given the fact that they require people to physically inspect all the electrical equipment on a regular basis.
Today, however, there is a powerful new option to help reduce the overall risk of an arc flash from occurring. This option is high-tech software tools that can help in planning and monitoring of electrical equipment and even offer recommendations on how to improve the safety of the facility.
There are many great companies that have developed high quality software that is either focused specifically on arc flash safety or else can be used for that purpose. Taking some time to learn about each of these options will help you to see which one is right for your company.
Some companies will only need a single type of software to handle their specific needs. Others, however, can benefit from multiple different software suites. Knowing what your facility needs can help you to ensure you are able to have the safest facility possible when it comes to arc flashes and other electrical hazards. Whether you are able to invest in just one or your company has the funds to use several, it is always best to know all your options before moving forward.
SKM Systems Analysis Inc
SKM Systems Analysis, Inc has been around since 1972 and is based in California. The company was started by a team of three engineers who wanted to help improve electrical design using automation and computer systems. The company provides electrical planning, evaluation and safety software to many users around the world.
Their software is frequently used at regional electricity sub-stations, wind farms, hydro-electric dams and much more. Anywhere that electricity is produced, stored or used in large quantities can benefit from the products offered by SKM System Analysis, Inc. Even if your facility is only using one high voltage machine it may be well worth it to invest in the type of software offered by this company.
They started by developing a system for power analysis called DAPPER. This software was run on a mainframe located in the UCLA Computer Center. Mainframe computing was, at the time, the only way to get the complex calculations that were required in order to gain the results they were looking for. After several years of development, the DAPPER system was up and running on the Control Data Corporation mainframe by 1978. It operated in time-share mode and was able to be accessed and used by engineers around the world.
Over the years SKM has grown and innovated in many ways, but has continued to maintain its focus on using technologies to improve electrical systems. Today, software by this company is used by 39 of the top 40 electrical engineering firms around the world.

Arc Ad (Arc Advisor)
Arc Advisor is a company that designs PC and mobile software to help businesses create a safe working environment for those who work on or service any type of electrical systems. They provide both online, PC based and mobile software for short circuit fault current as well as arc flash analysis.
First, look at the following two mobile apps which are available for Android and iOS devices. Both of these mobile apps are free to download and use as much as you'd like. They do, however, have 'professional' versions that you can buy if you need to unlock some extra features that can be very helpful. When it comes to industrial software of this type, however, even their premium price is extremely inexpensive.
Arc Flash Analytic is a free app (with some in-app purchases) that was developed by Arc Ad. It is based on the IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations. It is easy to use and makes it quick to calculate things like incident energy and the arc flash boundary. It can also help in determining limited, restricted and prohibited approach boundaries based on risk categories.
This app will take equipment configuration, gap between electrodes, the type of grounding used, the short circuit fault current value and the total system input voltage and then determine the arcing fault current at any potential point where the fault could occur. This can help make it easier to properly use protective devices so that employees in the area can be safe.
In addition, the app will allow you to document information about a given area, take pictures of any device that is of concern, add fuse and/or circuit breaker data and much more. The app is primarily used for electricians or safety specialists who work on or around electrical devices.
Another great perk of this particular app is that it allows you to create custom safety labels based on the information gathered through the app. If your mobile device is connected to a network, you can then print these labels on your LabelTac 4 PRO label printer quickly and easily. There are many types of labels available through this app so you can ensure all your electrical equipment is properly identified for the highest levels of safety.
Many people will find that having the ability to print warning and hazard labels right from a mobile device is a very powerful feature. Safety professionals can take their smart phone or tablet around to the different areas of the facility. When they find a location that can benefit from a safety label, they can have it created and sent to the label printer immediately. This can save a lot of time and effort since you don't have to return to a PC or order labels from a third party print shop.
Short Circuit Fault Current Calculations is the name of the other app that is developed by ArcAd. This is a fairly simple application that can perform short circuit fault current calculations quickly and easily. It uses a three-phase electric power system and factors in a variety of parameters to provide accurate information.
You can add in and remove different components, wiring and even a motor to help simulate real life electrical environments. When ready, just tape the button to run the calculations. You'll get an estimated short circuit current at each busbar. This can help you to understand where there may be potential problems before you actually implement a system in real life.
When used properly, this app can allow you to dramatically cut down on the risk when creating new circuits or adding new devices. By keeping your simulation up to date, you'll find that this app provides you with a significant amount of important information that can be used to streamline day to day tasks of many electricians or facility maintenance professionals.
In addition to their mobile apps, ArcAd has a nice PC based tool called DC Arc Flash Analytic. It functions more or less like the Arc Flash Hazard Analytics app except it is on your Windows based PC. This makes it far faster and easier to determine approach boundaries and hazard risk category.
Most modern computer systems will be able to run this software without a problem. In fact, many facilities will have it installed on a laptop, which can be brought around through the facility so that electricians or safety managers can access, update or review the information as they need it.
If you prefer working on a laptop or PC rather than a mobile phone or tablet, this is clearly the better option. Of course, you can always use both versions to get the most out of any situation.
The biggest thing to keep in mind when looking at this software is that it is for DC environments only. If your facility uses AC for anything you will not want to use this software.
Easy Power is another electrical software design firm and one that is providing the industry with a lot of great options. They make a variety of different products including their Easy Power safety tracker and online designer.
What is most important here, however, is the Arc Flash Analysis software. This is a comprehensive productivity platform that is used for performing arc flash analysis. It can also be used to help ensure your facility is in line with OSHA and NFPA standards (including the 70E requirements).
The software itself is used by electricians and safety professionals who either design, implement or maintain a wide range of different electrical systems. This particular software can also be purchased as part of the Easy Power Electrical Software Suite.

They can actually have highly trained and experienced professionals in each area provide you with direct assistance either on site, over the phone or online.
This is an excellent way to get the expertise that many facilities occasionally need, without having to hire someone on full time to fill these roles. The fact that CYME provides these and many other great services makes them a popular choice when companies are looking for any type of arc flash hazard software today.
When it comes to arc flash hazards, CYME has long been a safety leader for their customers. Their software has a dedicated module for arc flash hazard analysis that can help assess the risk of this issue.
The arc flash hazard analysis module takes all the needed parameters used for determining the risk level and compiles them to provide safety procedures based on your specific situation. It can calculate things like short-circuit fault current levels and provide information on how to reduce the possibility of this happening.
If your system changes, it just takes a few clicks and adjustments to update your 'virtual' system to reflect it. Of course, you can make adjustments in the virtual environment first to see what type of impact it may have. Many facilities find that this is a great way to do quick and easy testing before making any changes to a live environment.
Keeping your virtual system up to date can help ensure you always know what you can expect before it is put into place. Of course, you'll still need to do manual inspections and other work in your live environment, but this type of software provided by CYME can help you to reduce risks from unexpected intersections within electrical systems.
Another nice thing about this software is that after you have entered all the detailed information about your electrical systems, you can easily create warning labels to apply to your systems. These labels will contain exact details from your systems so that employees in the area can quickly read through them and understand what types of safety efforts are needed.
For example, if a particular machine is operating with high voltage levels, it is likely best to wear protective gear whenever coming anywhere near it due to the risk of an arc flash. For low voltage equipment, however, it may be acceptable to just wear protective gloves while actually working on the machine.
The bottom line here is that you can have your warning labels identify the exact hazards and proper responses to them. Once you've got the label information entered into the software it can be printed to your LabelTac 4 PRO label printer in just moments. This is the fastest, easiest and most affordable way to get custom labels for your facility.
Whether you need to just print one label or many, they can all be designed from within the software package provided by CYME, which is yet another reason why they are one of the leaders in electrical safety and power engineering software solutions.
CYME's arc flash module is fully compliant with all the major industry standards when it comes to analyzing arc flash calculations. This includes the NFPA-70E and the IEEE-1584 standards. Their new algorithms in the most recent version of their software are based on NESC 2007 and the Heat Transfer Model.
High Quality Arc Flash Labeling
As you may have noticed throughout this page, one of the main things that each of the software platforms have in common is the ability to create and print some type of arc flash labeling. This is an essential component because of the fact that proper labeling of electrical equipment is critical for keeping your facility safe.
Not only does it help improve safety, but it is also necessary for facility compliance with OSHA and other standards. No matter which of the software packages you choose, you will need to have a good printer to be able to actually create the labels themselves.
Of course, these label printers can be used to print any type of label that you may need for your facility, not just those related to an arc flash. Having this type of printer on site can be a great convenience for many departments while also improving overall visual communication and safety throughout the facility.
