Short Circuit, Device Coordination and Arc Flash Studies
Within each facility The Estopinal Group designs, the safety of personnel and the reliability and performance of equipment are top priorities. We create a safe environment by performing short-circuit, protective device coordination and arc flash hazard studies.
A short-circuit study will identify:
- Available fault current levels at various locations in the facility
- Whether the system and equipment can withstand the available fault current
- The ratings of equipment for future expansions, and improve the reliability of the system
A protective device coordination study will:
- Prevent extensive facility outages and safety hazards to personnel and equipment
- Enable protective devices to trip in a desired sequence during a fault condition
- Isolate the problem area from the entire power system and ensure that all electrically powered equipment is adequately protected
An arc flash hazard study will:
- Determine the risk of personnel injury as a result of exposure to incident energy released during an arc flash event
- Provide recommendations for appropriate arc flash hazard protection
- Inform personnel of existing arc flash hazards and comply with OHSA, NEC and NFPA 70E requirements
Following the study, personal protective equipment (PPE), such as gloves, eye protection, and flame retardant shirts and pants can be selected.
