Engineering Studies:
Our staff can provide the following engineering studies and provide detailed graphs, charts and reports. The results of these studies are used in the final product application or design to reduce the risk of shock hazard to maintenance or fire fighting personnel.
- Short Circuit and Protective Coordination Study
A coordination study is critical for the safe, efficient, and economical operation of any electrical distribution system. A Short Circuit Study will help to ensure that personnel and equipment are protected by establishing proper interrupting ratings. When an electrical fault exceeds the interrupting rating of the protective device, the consequences can be devastating, including injury, damaged electrical equipment, and costly downtime. A Coordination Study maximizes power system selectivity by isolating faults to the nearest protective device, as well as helping to avoid nuisance operations that are due to transformer inrush or motor starting operations. - Arc Flash Hazard Analysis Study
An arc flash occurs when short circuit current flows across a gap creating an arc. The resulting spark or explosion can cause serious damage, injury and death. OSHA, NFPA 70E and CSA Z462 mandate that the employer assess the hazards in the work place, select, have, and use the correct Personal Protective Equipment (PPE) and document the assessment. An arc flash study is used to determine the incident energy exposure for a worker’s chest and face if an arc flash occurs. It also determines the level of PPE a worker must wear based on the possible incident energy exposure. It also determines the flash protection boundary.
A detailed arc flash study requires performing calculations to estimate the magnitude of incident energy exposure. These calculations are based on specific details of the equipment, including its location, available short circuit current, device clearing time, grounding, arc gap distance, equipment type, and many other factors. The results are used to determine the flash protection boundary and required level of PPE. This information, as well as data regarding electric shock protection and approach limits, is included on the detailed arc flash warning label placed on the equipment under study. Before conducting live work, a qualified worker can refer to the label and obtain all of the data necessary for the shock hazard and flash hazard analysis.
