Handy Arc Flash

The Handy Arc Flash Calculator software calculates arc flash fault current, incident energy, arc flash boundary, and hazard level based on IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations.

The software was developed by Electrical and Control Engineering Department at Electricity Generating Authority of Thailand for 2014-2015 KAIZEN activities. Handy Arc Flash Calculator is fully functional and welcomed to be freely distributed.

Software features includes:

* Three-phase bolted short circuit current calculation from transformer kVA and %Z

* Direct input for 3 phase bolted short circuit

* Equipment type selection

* Ground selection (grounded or ungrounded)

* Default gap and working distance as per IEEE 1584

* Direct input for protective device trip time

* Four IEC overcurrent curves selection for trip time

* Two stage definite time curves selection for trip time

* Circuit breaker trip time
