PD UPDATE: breaker plan

Log Number: 3912567Logbook(s): Tags: Entry Makers: beneschBody: 

The lab does not have a spare breaker matching the one supplying the Arc 5 box supply. In the West Arc service building (aka NAB) there are three breakers of that size, supplying arcs 2 and 4 and RSEP8A. In a conference call including Steve Suhring and Sarin Philip by phone; Micheal Merz, Mark Todd, Daniel Moser, Paul Powers and Jay Benesch in the MCC, it was decided to move the RSEP8A breaker to the SAB and the Arc 5 breaker, after trip delay and other programming changes, to the RSEP8A slot.

PD UPDATE: arc 5 power supply

Log Number: 3912495Logbook(s): Tags: Entry Makers: beneschBody: 

The breaker on the distribution panel feeding the arc 5 power supply tripped for the fouth time in 36 hours. A recorder on the output of the breaker, as it enters the supply, shows two anomalies since it was installed. In one a phase dipped to 200 V. In the second a phase vanished. Last night DC Power tried and failed to persuade FML that the problem was in the breaker. FML just arrived on site. DC Power has been on site for about an hour. IMHO the only option is to replace the breaker; I hope we have a spare. This will require taking down the distribution panel.
