Solar project ARC Flash
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
- Site visit for data collection and verification
- Arc Flash hazards analysis
- Fault current calculation
- Protective device coordination study
- Personal Protective Equipment selection
- Arc Flash label printing and / or Installation
- Arc Flash hazards mitigation strategy
