Electrical Edge: Arc Flash Calculator

Electrical Edge: Arc Flash Calculator is a tool developed to solve the challenge of performing arc flash calculations. It serves to increase the users understanding about the inner workings of electrical equipment and components. It provides electrical engineers, planners, safety POCs and field technicians with crucial information about how an electrical system will behave during a fault condition.

This calculator is based on the IEEE STD. 1584-2002, Guide for Performing Arc-Flash Hazard Calculations. It is designed to create the most clear and comprehensive user experience possible; calculating arc fault current values has never been so quick and simple. The calculator provides the user with the following:

• Bolted Fault Current
• Arcing Fault Current
• Incident Energy
• Flash Hazard Boundary

By allowing the user to change a variety of different parameters, they are able to use this arc flash calculator on a wider range of electrical equipment with ease.

Notable Features:
〉Clear, simple and comprehensive design
〉Number pad interface allows for quick number entry
〉Reference guides for Conductor Impedance, Bus Gap and Distance X-Factor values
〉Help guides for Arc Duration and Working Distance values
〉Parameter flexibility, including:
○ In-box and open-air Arc Type
○ System Voltage range between 208V – 15kV using an empirical model, and over 15kV using a theoretical model
○ System Fault Current range between 700A – 106kA
○ Bus Gap range between 10 – 153 mm
○ Conductor Impedance for various cable sizes
○ Grounded and ungrounded systems

With this valuable tool in hand, any engineer and field technician can feel equipped to work with arc flash hazards in check.
