Electrical & Instrumentation


HEA’s electrical team develops plans and specifications that conform to local building and electrical codes and MSHA health and safety requirements utilizing the latest technology in computer networking to directly control processes, provide data management reports, and organize maintenance functions. HEA’s Power Transmission and Distribution team provides engineering calculations and designs utilizing ETAP Electrical Power System Design Software for the design and optimization of power transmission and distribution systems, including arc flash, load flow, short circuit and transient stability analysis. HEA uses PLS-CADD software to design the transmission line and optimize pole locations, sag and tension.  HEA uses Dialux to energy model Lighting in 3D to solve lighting and shadow conditions in the planning process.
