Completion of B2 Training

B2 training for the system is now complete.  During the week, the PI team got to carry out some dry practise runs on the various maintenance activities that they will be expected to complete during the life of the system.

In the picture above, John and Matt have just completed an exercise to change out a blown lightning arrestor.  It lives inside one of the High Voltage modules in the PFE and involves a lengthy isolation and shut-down process before the module can be pulled out.  In all the process takes about 20 minutes to complete, not including the powering up of the PFE afterwards.  During this time, the system would continue to operate as Guam would be able to ‘Single End Feed’ the entire system, thus not interrupting traffic.
