ELECTRICAL SYSTEM (MORRONI ENGINEERING, INC.) <br /> Power for the Robinson Seepwater Pump station will be derived from Climax's <br /> 13.8 KV overhead distribution system. There is an existing overhead system in the area <br /> of the proposed pump station, for estimating purposes 300 feet was used for the distance <br /> between the overhead lines and the pump station. A new pole, with a 3-pole interrupter <br /> switch and fused cut-outs, will be set"next to the existing overhead service and a 15 KV, <br /> 3-phase line will be tapped and fed to the new pole. From the pole, a 15 KV, 3 phase line <br /> will feed underground to a 15 KV pad-mounted fused switch, and subsequently to the <br /> primary side of a 2,000 KVA pad-mounted transformer. Both the high-voltage switch and <br /> the transformer will set next to each other approximately six feet from the pump station. <br /> The underground high voltage cables will be in PVC conduit and concrete encased in a duct <br /> bank. A spare 4" PVC conduit will run parallel with the 15 KV line, and be designated as <br /> a "spare". <br /> Preliminary load calculations indicate that the full load amps for the station will be <br /> approximately 1,542 amps. These calculation are based on the assumption that all four <br /> vertical pumps will be 300 hp in the future. Presently the Station is configured for three <br /> 300 hp pumps and one future 150 hp pump. Calculating continuous loading on this <br /> system will result in the service requiring to be approximately 1,928 amps. <br /> The secondary of the transformer will feed into the Main breaker section of a 2000 <br /> amp, 480/277 volt, 3 phase, 4 wire, motor control center. The main breaker will be a <br /> 2000 Amp, 100% rated breaker, with solid state trip and ground fault capabilities. In <br /> addition a Basler 47N negative sequence protection relay will be installed, for overvoltage, <br /> undervoltage, and single-phase protection. The service entrance will be a concrete <br /> encased underground feed between the transformer and the main breaker. <br /> 12 <br />
