JJA is a leading consulting engineering firm established in 1978 in Dallas, Texas, and has been providing power system analysis since our inception with an emphasis added to ArcFlash Hazard Assessments in 2003.  We have standardized on the use of EasyPower® software, developed by ESA, Inc. located in Portland, Oregon.  The analysis is based on the NFPA-70E and IEEE-1584 standards, which require a detailed model be developed for the electrical distribution system.


JJA has performed Power System Studies for mission critical facilities, commercial office buildings, corporate campuses, industrial, manufacturing, and corporate campus projects.  Power System Analysis performed by JJA includes an overview of the electrical distribution system using three (3) separate but integrated steps.  Each step of the study; the Short Circuit Study, the Coordination Study and the Arc Flash Study, work together to determine potential concerns and possible methods of improving the selective coordination of the electrical distribution system and provides labeling compliance with permanent labeling of the equipment per NFPA 70E and OSHA.


JJA is committed to providing a safe working environment for our Clients by providing a complete electrical distribution system power study.
