ArcSafety™ - AC Arc Flash
Arc Flash Analysis
The Arc Flash Analysis program is a completely integrated module that solves multiple scenarios to determine worst-case arc flash energy levels. The Arc Flash calculation software module also produces professional reports and high quality arc flash hazard labels at a press of a button.
The Arc Flash Analysis module also includes comprehensive single phase and three phase arc flash calculations as well as an invaluable arc flash analyzer tool to summarize results from the arc flash study.

This webinar will provide an overview of the fundamental differences between the IEEE 1584-2018 and existing arc flash methods. To better understand how the 2018 model combines empirical and arc flash physical behavior, the presentation will cover background and insights into the model development validation.
ETAP Arc Flash Analysis automatically estimates the Incident Energy released in the event of an arc fault and determines the required Flash Protection Boundary.
ETAP makes the creation of multiple configurations and operating modes for the system being modeled easy once the model has been created and then the available incident energy for each bus in each configuration can be determined and compared. The worst case incident energy and corresponding personal protective equipment (PPE) can be put on arc flash labels to be applied to the equipment.
ETAP 7.1 now includes the ability to customize and link arc flash electrical safety labels using Microsoft Word. This webinar explains step-by-step instructions.

ETAP Arc Flash IEEE 1584-2018
ETAP Arc Flash Analysis software is used to perform arc flash analysis for systems from 0.208 kV to 15 kV in accordance with IEEE 1584-2018 “IEEE Guide for Performing Arc Flash Hazard Calculations.” The software determines the incident energy and arc flash boundary values required to comply with NEC equipment labeling. It also provides hazard evaluation for shock protection and arc flash PPE according to NFPA 70E 2018.
Hazards of Single-Phase Arc Flash
This article presents different methods for assessing the hazards of high- and low-voltage 1-phase equipment. One common question being asked is how to determine the hazard level associated with 1-Phase (1-P) Arc Flash (AF) incidents. There is very little information about this type of circuit in the available guidelines such as CSA Z462-08, NFPA 70E 2009 & IEEE 1584 2002. If the right risk level is not properly determined, we run the risk of over-protecting or under-protecting personnel that are working on this type of electrical system. The objective of this article is to present different methods for assessing the hazards of high and low voltage 1-P equipment, and to justify the results taking into consideration the behavior of arc faults at different voltage levels.
