Background
The three 60V, 165A, 10kW bulk power supplies require remote turn on - turn off capability. No monitoring is needed. Ethernet controller interface specified.
Problem
Power supplies operate in voltage, not current mode. Ethernet controller does not accommodate. No front panel, local control mode
Solution
Use manually controllable 60V, 165A, 10kW power supply

Remove Two 60V, 165A, 10kW Ethernet power supplies (not yet purchased, bids due 10/17)
Increase quantity of 25V, 375A, 10kW power supplies by two for BC1
No change in overall quantity or cost
Delete two 25V, 375A, 10kW power supplies for BC1 not yet purchased
Write purchase requisition for three 60V, 165A, 10kW MCOR local control bulk power supplies instead of one bulk for the Sector 21, BC1 MCORs – Net 1 add
Increase in quantity - zero
Overall change 0 10kW power supply, 0k$

Ground Fault Detection and Protection
October 14, 2005 10Injector, Sector 21, BC1 MCOR Bulks/Ground Fault
The MCOR System does not include ground fault detection and protection
Why Ground Fault Detection and Protection?
Prevent power supply current from straying outside magnet
Can lead to equipment damage or fire
Current read by power supply transductor is not the magnet current
Ground current fluctuates causing erratic magnet current
The next few slides propose a ground fault detection and protection system.
