_E`i4`iT PROJECT EX P,IPNCE - ARC FLASH PROJECT EXPERIENCE Elsinore Valley Municipal Water District, Arc Flash Study To assist Elsinore Valley Municipal Water District in its mission of providing customers with safe, affordable water, P2S provided an Arc Flash Risk Assessment of electrical distribution equipment at over 158 district sites. Our team created a Short Circuit Contribution Report, an Overcurrent Protective Device Coordination Study, an Arc Flash Risk Mitigation Report and a final Arc Flash Risk Assessment Report for the district. We will be conducting (1) 3-hour Arc Flash and Shock Hazard Electrical Safety training session for district electrical and maintenance personnel. Our team collected data, verified equipment in the field, created one -line diagrams and safely obtained equipment information for: distribution equipment types and ratings, conductor sizes, conductor lengths, overcurrent protection, and transformer ratings and impedances. We created power system study models in ETAP, based on the field surveys and verified as-builts. We modeled and analyzed switching configurations for the most conservative results for Short Circuit, Coordination, and Arc Flash. We are now in the final stages of the project as we coordinate with Southern California Edison to obtain the utility's contribution to fault current to complete our final analysis. P2S provided training to facility staff.

The purpose of the study was to develop a computer model using Electrical Transient and Analysis Program (ETAP) based on the existing single line diagrams, and data gathered during a field survey of the existing equipment ratings, protective device settings and feeder sizes and lengths. The model has used by the program to calculate the system available fault currents and incident energy levels due to arc flash at each of the medium and low voltage distribution panels and prepare device coordination curves for evaluating the existing overcurrent device settings for coordination with upstream and downstream protective devices. The results of the electrical system analysis were used to make recommendations for improved system coordination and arc flash mitigation measures. P2S also provided labels for the medium and low voltage electrical distribution equipment such as medium and low -voltage switchgear, load interrupter switches, MCC and low - voltage panels. P2S provided training to facility staff. PROJECT DATES: February 2015- April 2016 OWNER CONTACT: George A.
