What is a PTW model?
PTW Viewer. PTW Viewer is the perfect tool 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 time-current curves, print arc flash labels, and many other activities.

How do you calculate arc flash?
- STEP 1: DETERMINE THE ARCING CURRENT. For low voltage electrical systems (<1 kV), the arc current is determined using formula (1).
- STEP 2: DETERMINE THE NORMALIZED INCIDENT ENERGY.
- STEP 3: EVALUATION OF INCIDENT ENERGY.
- STEP 4: FLASH PROTECTION BOUNDARY.
Does OSHA require arc flash analysis?
Arc-Flash Hazard Assessments are required by OSHA and NFPA 70E as a part of an Electrical Hazard Assessment. Arc-Flash Assessments are a serious life safety issue and essential part of a safe and comprehensive electrical safety program.

What is cal cm2 mean?
Calories per Centimeter Squared
Calories per Centimeter Squared (cal/cm2): This is a number identifying the amount of energy that can be delivered to a point at a particular distance from an arc flash. Once this value is known, the ATPV rating of the flash clothing required for work at that distance from the potential flash hazard is also known.
What is conductor gap?
The conductor gap causes an increase in incident energy and higher arcing currents due to the longer arc length. The distance exponent has more to do with the geometry of the equipment.
How often is arc flash required?
Arc Flash Training Requirements Employees must be retrained in safe work practices and in any changes to the NFPA 70E standard at least once every three years. Training is also required when new equipment is added, after a change in job duties, or after failed inspections.
How do I add a device to SKM library?
Expand the appropriate library category. 4 – Select the protective device(s) you wish to copy. -To select a single protective device, click once on the manufacturer’s name. -To select multiple (contiguous) devices, press and hold the key and select the first and last device.
What is PSS Sincal?
PSS®SINCAL provides distribution engineers with the simulation tools they need for the planning, design, and operation of power distribution networks. It can be used in balanced, unbalanced, radial and meshed networks – including single-phase and multi-phase (incl.
