RELEVANT PROJECT EXPERIENCE <br />P2S INC. <br />CITY OF SANTA ANA PUBLIC WORKS <br />ARC FLASH ANALYSIS & ELECTRICAL SAFETY PROGRAM <br />ARC FLASH PROJECT EXPERIENCE <br />Elsinore Valley Municipal Water District, Arc Flash Study <br />To assist Elsinore Valley Municipal Water District in its mission of providing customers with safe, affordable <br />water, P2S provided an Arc Flash Risk Assessment of electrical distribution equipment at over 158 district sites. <br />Our team created a Short Circuit Contribution Report, an Overcurrent Protective Device Coordination Study, <br />an Arc Flash Risk Mitigation Report and a final Arc Flash Risk Assessment Report for the district. We will be <br />conducting (1) 3-hour Arc Flash and Shock Hazard Electrical Safety training session for district electrical and <br />maintenance personnel. <br />Our team collected data, verified equipment in the field, created one -line diagrams and safely obtained <br />equipment information for: distribution equipment types and ratings, conductor sizes, conductor lengths, <br />overcurrent protection, and transformer ratings and impedances. We created power system study models in <br />ETAP, based on the field surveys and verified as-builts. We modeled and analyzed switching configurations for <br />the most conservative results for Short Circuit, Coordination, and Arc Flash. We are now in the final stages of <br />the project as we coordinate with Southern California Edison to obtain the utility's contribution to fault current <br />to complete our final analysis. P2S provided training to facility staff. <br />PROJECT DATES: January 2017- Ongoing <br />OWNER CONTACT: <br />Jon Moore CHST Safety Technician <br />951.674.3146 x8311, jmoore@evmwd.net <br />PROJECT OWNER: Elsinore Valley MWD <br />PROJECT TEAM: <br />Aravind Batra, Principal -in -Charge <br />Marco Cabibbo, PM, Electrical Engineer <br />Cal Poly Pomona, Arc Flash, Short Circuit and Coordination Studies <br />P2S provided electrical engineering services for campus -wide arc flash, short circuit and coordination studies <br />in accordance with IEEE 1584, NFPA 70E and NEC from the incoming medium voltage utility service down to <br />low -voltage panels. The purpose of the study was to develop a computer model using Electrical Transient and <br />Analysis Program (ETAP) based on the existing single line diagrams, and data gathered during a field survey <br />of the existing equipment ratings, protective device settings and feeder sizes and lengths. The model has used <br />by the program to calculate the system available fault currents and incident energy levels due to arc flash at <br />each of the medium and low voltage distribution panels and prepare device coordination curves for evaluating <br />the existing overcurrent device settings for coordination with upstream and downstream protective devices. The <br />results of the electrical system analysis were used to make recommendations for improved system coordination <br />and arc flash mitigation measures. P2S also provided labels for the medium and low voltage electrical <br />distribution equipment such as medium and low -voltage switchgear, load interrupter switches, MCC and low - <br />voltage panels. P2S provided training to facility staff. <br />PROJECT DATES: February 2015- April 2016 <br />OWNER CONTACT: <br />George A.
