PROTECTION & SECTIONALIZING STUDIES, ARC FLASH HAZZARD ASSESSMENT
Improving system resilience through advanced protection and risk analysis
Help utilities ensure system safety, protection, reliability, and regulatory compliance by evaluating protective device performance, and identifying potential coordination challenges.
Comprehensive Protection & Arc Flash Services
These services help utilities to improve system protection coordination, reduce safety risks associated with fault current exposure, improve outage response and system protection performance, and maintain compliance with industry standards while ensuring the safe operation of electrical infrastructure.
Typical services include:
- Protection coordination studies for feeders, substations, and transformers
- Review and optimization of protection settings including relays, fuses, and reclosers
- Sectionalizing analysis to improve fault isolation and system restoration times
- Fault current calculations and evaluation of equipment interrupting ratings
- Arc flash hazard assessment in accordance with IEEE 1584 and NFPA 70E standards
- Development of arc flash labels and incident energy calculations
- Recommendations for protective device upgrades and mitigation strategies
- Time-current coordination (TCC) curve development and review
- Support for system modifications, new interconnections, and equipment additions
