The fifth and last group that has been added was not restarted.
The entire power station was not correctly performed vis a vis the failure of this group ...

We investigate with the concerned providers.

The problem has been understood.
The fuel gauge of the fifth generator was broken and it sends
misinformation.However the daily tank (small reservoir embedded in
the generator) was empty.

With no default, the group made three attempts to start (27 seconds in total)
and abandoned on an error "Failure to start." Following these 27 seconds, the other
groups are synchronized and delivered voltage after 37 seconds.


Our system of switch has therefore announced the groups out of time on startup
because one of the delayed group has been started. The time originally planned was 20 seconds and
was changed to 45 seconds to respond to this very special case of a group
that is slow to start in but it is not declared in default.

An upgrade of the switch program was installed.
We start the tests which are going to validate its good working.

The new program was validated.

Since we have electrical maintenances the next week, we are going to
do an endurance test this thursday on the power station of the
electrogen groups of Roubaix 1.
