Utility-Scale Solar Ontario

Hazard Analysis

Phoventus was contracted to provide engineering support of Solar project ARC Flash Assessments for 3 Ontario Utility-Scale Solar Projects.

Between December 3ʳᵈ, 2018, and February 28ᵗʰ, 2019, Phoventus provided a full-wrap arc flash study, including prerequisite studies and data collection. A site inspection took place between January 3ʳᵈ, and January 6ᵗʰ, 2019. The study was completed using ETAP 18.1.1 and included both DC and AC studies.

This work conformed to the following standards: ANSI (1/2 Cycle), IEEE
946, IEEE 1584-2002, DC Arc Flash (Stokes & Oppenlander).

Onsite assessments / Solar project ARC Flash

Several regulations, codes, and standards define requirements for Arc Flash safety, including OSHA, NFPA 70E, CSA Z462, IEEE 1584-2018, and NESC. Article 130.5 of NFPA 70E requires employers to perform an Arc Flash risk assessment for electrical equipment and to update the study every five years.
