ETAP Arc Flash Analysis

Reduce Risk

Improve Safety

Enforce Compliance

An effective arc flash safety program must be designed on a reliable foundation. As such, arc flash studies must be performed by qualified persons using a quality analysis tool which provide accurate results that you can trust and rely on!

Results You Can Trust

ETAP Arc Flash Analysis program is a powerful integration of ETAP’s intelligent one-line diagram, state-of-the-art protective device sequence of operation, and proven short circuit algorithm combined with ETAP’s extensive protective device libraries. Backed with embedded features and capabilities, ETAP Arc Flash Analysis automatically determines short circuit contributions, primary protective devices, fault clearing times and incident energies with a single click.

Unmatched Accuracy & Reliability

ETAP is the only high-impact electrical engineering software to comply with widely accepted and firmly established quality standards and regulations. Every release of ETAP is verified and validated against field results, real system measurements, established programs, and hand calculations in order to ensure its technical accuracy.
