  1. Mu2e Conventional ConstructionConventional Electrical Value Engineering Review of Mu2e 2/2013 Randy Wielgos

  2. Mu2e Site Electrical Loads R. Wielgos - VE Review

  3. Conventional Requirements Lighting Assembly/High Bay 85 foot-candles Tunnels 20 foot-candles Automated Controls AC Distribution 120/208 V – 20 Amp Quad Outlet @ 25 Feet 480 V – 60 Amp Welding Outlet @ 50 Feet Standby Power Available R. Wielgos – VE Review

  4. Generator 150kva Elevators, elevator equipment, and elevator machine room/controller cooling. Air handling systems for the ODH. Cranes Sump Pumps. Emergency/StandbyPower Systems Battery Fire detection and alarm systems. Exit sign illumination. Emergency lighting. * Tech equipment requiring UPS will be provided within that Level 2 R. Wielgos – VE Review

  5. Conventional Power Services Above Grade • 13.8 kV Pad Mount Switchgear • Oil Filled Power Transformer • 2000 Amp, 277Y/480 VAC Switchboards • 150 kW Emergency Generator • Power Supply Disconnects Above and Below Grade • Power Distribution Panels (Demarcation w/Exp.) • Welding Receptacles • Lighting Distribution Panels R. Wielgos – VE Review

  6. Electrical Services Beamline PS Disconnect Generator Transformers in Oil Containment Electric Room Panelboard Solenoid PS Disconnect 13.8 KV Switchgear R. Wielgos - VE Review

  7. Electrical Load Model Two Transformers 500 kVA “House Power” 1000 kVA “Power Supplies” R. Wielgos – VE Review

  8. 13.8kV Power System • Expand existing Delivery Ring (PBar) Feeder 24, fed from MSS • Current feeder replaced in 2005 • Second leg to be added Site Prep GPP • Breaker at MSS capable of full anticipated load • Configure system as Sectionalized Loop R. Wielgos – VE Review

  9. 13.8kV Power System Existing: 13.8kV Switch Transformer Feeder & Duct Mu2e AP-10 Proposed: 13.8kV Switch Transformer Feeder & Duct AP-10 MC-1 AP-50 AP-30 R. Wielgos – VE Review

  10. Status Summary • Final Electrical Loading Criteria in Process • 2nd 13.8kV Feeder Cable may be Needed • Options for Building Electrical Service • Two Small Transformers • Smaller Electrical Panels • Separated Loads • One Large Transformer • Future Capacity Benefit • Demarcation with Experimental Equipment Determined R. Wielgos – VE Review
