Arc Flash Detection Systems
using Optical Sensors

  • Remediation (using IE TRAP® products by ZMAC) 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 elevated risk and nuisance tripping

  • Base package capable of accepting 8 arc flash sensors.  Optional capacity is available

  • Outputs include dry contacts for pick up by SCADA system (PLC, DCS, etc.) for control room monitoring of trip events and system ok.

  • This is a cost effective best-in-class system. 

  • 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.
