The City of Benicia has a large wastewater treatment plant and several sewage lift stations that could require operators to work on energized electrical equipment. In an effort to reduce risk to personnel, Cannon was selected to perform an arc flash analysis.
Cannon’s scope included researching existing data and documentation, gathering field data, creating electrical models of the sites in power systems software (SKM Power Tools), and analyzing the results. As well, the City wanted to mitigate the incident energies to levels where the City personnel would not have to wear personal protective equipment (PPE) suits, but wear minimal PPE instead. Cannon modeled different scenarios for the City and provided recommendations on equipment to install to reduce the incident energy levels. The results of the analyses of all the sites were presented in a report, and Cannon prepared and installed arc flash hazard labels on the electrical equipment.Back to Service
