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.
