Substation Remediation using an Arc Flash Detection System

  • Substation remediation protects electrical workers from injury and prevents destruction of equipment.

  • The arc flash detection system trips an upstream device upon detection of arc flash light.  The trip signal assertion is accomplished in 1mS.

  • It is possible in most cases to remediate the complete substation to several calories depending on transformer size and upstream device performance

  • System facilitates full coordination (in other words adequate time separation between TCC curves) in most substation protective relay schemes

  • System does not require maintenance mode or low instantaneous settings that in other designs can allow nuisance tripping

  • Base package capable of accepting 16 arc flash sensors.  Optional capacity is available

  • This is a cost effective best-in-class plug-and-play system.  No PC is necessary for commissioning and no adjustments are necessary for optimal performance

  • One system covers one complete single-ended substation lineup

  • Two systems covers one complete double-ended substation lineup

  • Pre-engineering and detail engineering resources are available on request​ to create: project documents (SOW, etc.), protective device setting review with recommendations, sensor location layouts, commissioning, and construction support

  • NEC, NFPA-70E, OSHA  -  Aligns with the intent of the 2017 NEC article 240.87 (ARC Energy Reduction), the NFPA-70E (standard for electrical safety in the workplace), and OSHA.
