Mines run large medium-voltage distribution systems, high-horsepower motors, and dispersed loads where an electrical fault is both a safety hazard and a production risk. Canfield Engineering & Integration delivers the power system studies and arc-flash analysis that keep mining operations safe, compliant, and reliable across the Southwest and Mountain West.

Why mining operations need power studies

OSHA and NFPA 70E require employers to assess incident energy and label equipment so crews know the hazard before they open a panel. Beyond compliance, an up-to-date study is what keeps a mine running: proper protective-device coordination isolates a fault to the smallest possible area instead of tripping an entire circuit, and load-flow and motor-starting analysis confirm the system can carry expansions and start large drives without sagging voltage.

What CEI delivers

• Short-circuit and fault-current analysis
• Protective-device coordination studies
• Arc-flash incident-energy analysis and equipment labeling (IEEE 1584 / NFPA 70E)
• Load-flow, motor-starting, and voltage-drop analysis
• Harmonics and power-quality evaluation
• Grounding studies and system modeling in ETAP and SKM
• Remediation design and field labeling support

Experience across AZ, NV & CO mining

CEI has completed power studies, arc-flash analyses, and dewatering and substation designs for copper, molybdenum, and gold operations across Arizona, Nevada, and Colorado. Our engineers work in live mine environments, coordinate with site electrical crews, and deliver labeling and documentation ready for the field.
