6.30am

Woken up by alarm to a brisk morning in Tamworth. A little far from home but there is a buffet  breakfast waiting downstairs with my name on it.

I am in Tamworth after travelling up yesterday for a fault investigation on a failed Capacitor bank can. Bulging on one capacitor can was identified during a visual inspection as a result of the Protection tripping the Capacitor bank. The fault was decided to be investigated further after testing of the Capacitor bank showed no problem, however an issue was identified following an analysis of the Protection fault records. Simulations were ran and the results were found to be similar to the protection fault records supporting the theory that there were repeated spark overs across one row of capacitor elements in one of the capacitor cans

7.10am

Time for the long 5 minute drive to the Tamworth Depot.

7.15am

Introduced to some local staff. It is always good to meet staff face to face having talked to them over emails and phone calls many times.

7.30am

Set up Laptop and check emails, responding to any priority work. This can involve planning or estimating customer work, providing support to maintenance staff, Fault investigations, reporting and documentation reviews. Can't forget to also make myself a coffee.

8.00am

Meet with team for risk assessment and discussion on hazards, controls and how the day's work will proceed.

8.15am

Carried out inspection and analysis of the dismantled Capacitor Can. Closer inspection showed evidence of low energy discharges to the tank at the ends of the top 3 or 4 capacitor element. This further supported both the simulation and protection fault record findings.

Each Capacitor element is a long, flat sheet consisting of Dielectric and foil layers. This is then rolled up to form each element. The two foil layers are offset to avoid shorting once the ends of all the elements have been soldered together.

I had previously never seen inside a capacitor can, however I now have a good understanding of the internal construction as well as fault finding of capacitors.

11.40am

Finished gathering evidence for Investigation. Brief discussion with team on findings.

11.50am

Time to get on the road back to Newcastle.

12.30pm

Taking care of lunch and fatigue management with a stop in at Wallabadah on the way back to Newcastle. The burgers are worth stopping in for.

1.00pm

On the road again. Travelling back with Senior Support Engineer allowed time to be able to reflect on the findings and discuss any technical questions. Lots of time to pick out as much knowledge as I can from him.

4.00pm

Arrived back at Newcastle Depot. Finalised the car pool booking and returned the keys just in time to call it a day. 7.47 hours done, got to love a working a 9 day fortnight.

6.30pm

Whip up some dinner

8.00pm

Fit in a gym session now that it should be a little less busy.

9.00pm

Finish the day off with a shower and bed, ready to piece together all of the Information gathered from the investigation the following morning.
