ArcCalc - Arc Flash Calculator

Engineers and Inspectors now have access to an affordable calculator to quickly estimate the electrical arc flash hazard level at any location in a power system. The new calculator is called ArcCalc.

ArcCalc calculates the arcing fault current, determines the fault clearing time from the protective device settings, calculates the incident energy, flash boundary and PPE requirements, and produces warning labels and work permits in compliance with NEC and NFPA requirements.

ArcCalc is a perfect tool to estimate arc flash hazard levels when minimal system data is known or when there is insufficient time to build an entire network model. The calculator uses generous tolerances for utility, transformer, cable and motor data to calculate minimum and maximum fault currents. The minimum and maximum arcing fault currents are used to determine the trip time for the primary protective device and the resulting incident energy and flash protection boundary. The largest incident energy and required PPE are reported in custom label formats.

ArcCalc includes a large validated library of protective device trip characteristics to provide accurate trip times for the calculations. The calculator also includes a comprehensive report with input data and calculated results, a custom label designer, and support for plain paper and vinyl label printers.

Arc Flash Educational Video
Engineers, maintenance personnel, and inspectors have a new educational source to understand arc flash hazard calculations. The educational DVD discusses the difference between a bolted short circuit and an arcing short circuit, arc flash hazard labeling requirements, calculation methods, and the important relationship between the arcing short circuit and circuit protection response.

The free education DVD is a valuable resource to anyone who designs power systems or works on or near energized electrical equipment. The DVD video is 30 minutes in length and may be requested by calling (800) 232-6789, or by sending an email to arcflashDVD@skm.com

ArcCalc vs. PTW Arc Flash

How are they different? 
ArcCalc calculates the incident energy and arc flash boundary for a single point in a power system. Minimum and maximum arcing short circuit currents are calculated using broad tolerances to provide conservative results with estimated system data. 
PTW ArcFlash allows you to build a system model for your entire power system. Once the system model is built, the Arc Flash module calculates the incident energy and flash boundary at every location in the power system. 

Features that ArcCalc and PTW Arc Flash Share
* Both calculate incident energy and flash boundary values. 
* Both produce standard and custom labels 
* Both produce Energized Work Permits 
* Both calculate arcing fault current values 
* Both automatically determine the trip times from the protective device settings. 
* Both have a large validated library of protective devices. 
* Both follow the calculation methods outlined in IEEE 1584 and NFPA 70E. 

ArcCalc Advantages 
* Simple calculator-style interface. 
* Low cost ($995 for ArcCalc versus $3495 for smallest PTW combination with ArcFlash). 
* Intelligent default data for fault sources, transformers, cables and motors. 
* Intelligent default data for arcing fault variables including bus gap and working distance. 
* Automatically applies tolerances to determine min/max arcing fault currents to provide more conservative results with estimated data. 

PTW Arc Flash Advantages 
* Works from a full interactive model of the electrical power system. 
* Evaluates multiple levels of protective devices including mis-coordination. 
* Accumulates energy from multiple parallel fault sources automatically. 
* Integrated with protective coordination drawings to help evaluate alternative designs. 
* Stores and compares multiple operating scenarios. 
* Calculates and reports bus, line-side and load-side fault conditions automatically. 

PTW Arc Flash Evaluation calculates the incident energy and arc flash boundary for each location in a power system. Arc Flash saves time by automatically determining trip times from the protective device settings and arcing fault current values. Incident energy and arc flash boundaries are calculated following the NFPA 70E and IEEE 1584 standards. Clothing requirements are specified from a user-defined clothing library. Clearing times can be automatically reduced based on current-limiting capabilities.

PTW Viewer
This tool is a perfect way to provide an interactive electrical model to your customers. Rather than paging through long reports, your customers can display results on the interactive one-line, view coordination, print arc flash labels, and many other activities. The cost of the viewer is only a fraction of the full PTW application and with the Viewer there is no chance of inadvertent changes to the power system model. 

Here are just a few of the many things a user can do with the Viewer:
1) View, print, and export all study results.
2) Make new one-lines, pick existing components and expand the one-line.
3) Adjust component positions in existing one-lines and add annotations.
4) Modify datablocks and apply them to any one-line or TCC.
5) View and print standard or custom Arc Flash labels and energized work permits.
