Substation Remediation using a Protective Relay with Current Transformers 

  • Substation 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 excessive current on the equipment being remediated.

  • 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

  • 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.
