City of Everett 26 05 73.16 - 8 <br /> Inductive Charging Infrastructure for Everett Transit <br /> 3.4 LOAD-FLOW AND VOLTAGE-DROP STUDY <br /> A. Perform load-flow and voltage-drop study to determine steady-state loading profile of <br /> system. Analyze power system performance two times as follows: <br /> 1. Determine load flow and voltage drop based on full-load currents obtained in <br /> "Power System Data"Article. <br /> 2. Determine load flow and voltage drop based on 80 percent of design capacity of <br /> load buses. <br /> 3. Prepare load-flow and voltage-drop analysis and report to show power system <br /> components that are overloaded, or might become overloaded; show bus <br /> voltages that are less than as prescribed by NFPA 70. <br /> 3.5 MOTOR-STARTING STUDY <br /> A. Perform motor-starting study to analyze transient effect of system's voltage profile <br /> during motor starting. Calculate significant motor-starting voltage profiles and analyze <br /> effects of motor starting on power system stability. <br /> B. Prepare motor-starting study report, noting light flicker for limits proposed by IEEE 141, <br /> and voltage sags so as not to affect operation of other utilization equipment on system <br /> supplying motor. <br /> 3.6 FIELD ADJUSTING <br /> A. Adjust relay and protective device settings according to recommended settings <br /> provided by coordination study. Field adjustments must be completed by engineering <br /> service division of equipment manufacturer under "Startup and Acceptance Testing" <br /> contract portion. <br /> B. Make minor modifications to equipment as required to accomplish compliance with <br /> short-circuit and protective device coordination studies. <br /> C. Testing and adjusting must be by qualified low-voltage electrical testing and inspecting <br /> agency. <br /> 1. Perform each visual and mechanical inspection and electrical test stated in <br /> NETA ATS. Certify compliance with test parameters. Perform NETA tests and <br /> inspections for adjustable overcurrent protective devices. <br /> END OF SECTION 260573.16 <br /> 26 05 73.16 - 8 COORDINATION STUDIES <br />
