Recurrent Energy New Liskeard AC & DC Arc Flash Incident Energy Analysis

Project Summary

Our team performed an Arc Flash Incident Energy Analysis in accordance with IEEE 1584-2018 and CSA Z462-24, utilizing ETAP software to model the system from the 115 kV level down to 120/208 V AC/DC distribution. The scope of work included:

• Performed an Arc Flash Incident Energy Analysis in accordance with IEEE 1584-2018 and CSA Z462-24 utilizing ETAP electrical power system analysis software.
• Performed a site wide electrical system audit to gather the required information to develop a detailed impedance model of the system from the 115kV voltage level through to the 120/208V AC/DC distribution.
• Provided a detailed report including the incident energy levels at all system buses with recommendations to reduce the incident energy level in areas which exceeded 12.0 cal/cm2 (typical arc thermal performance value of arc-rated work wear).
• Provided and applied arc flash warning labels on all equipment included in the assessment including information on incident energy, arc flash protection boundaries, working distances, voltage level, etc.
