• “MAINTENANCE ONLY AFTER THINK”• WHAT FOR Maintenance?
– To avoid some unavailabilities;– To prolong useful life of assets;
• WHICH Target?– Quality and continuity in supply
• HOW?– To maximizing intervals (time between two consecutive maintenance
actions);– To minimize costs (not to support of any more)
• BASIS– Expert knowledge of article to supporting;– Historical behaviour – statistical of article to supporting.

Pilot experience (III)
• Transducers CALISTO– Dissolved gases and oil dampness
Analyzer– Sending signals to the monitoring
equipments (AREVA MS-3000 óABB TEC 2.0)
Pilot experience (IV)
Up:• Dissolved gases analyzer Hydran. Send
signals to the monitoring equipment
Right:• Monitoring equipment ABB TEC 2.0.
Pilot experience (V)
• Monitoring equipment AREVA MS-3000– PC embedded to get information– Transmits data to the local PC (CITCEA)
for its treatment and later storage.
Pilot experience (VI)
• Protection relays AREVA MiCOM P-132– It is send the MT cells switch
state to the PC
Pilot experience (VII)
MONTSE • Elaborated equipment by NÚCLEO• Transducer of signal relays AREVA
MiCOM to the local PC.
Pilot experience (VIII)
• Centralizer enclosure TR-5• Local Computer. Receiving information TR-5, TR-2, and MT switches.
– Sending information to the Corporative repository (PI)

PROCESSING INFORMATION
• Incidental study analysis
• Analysis and study of behaviour in real time
• Normal behaviour models
Incident history analysis
Own development of applications for analysis and study of the incidents by MATLAB
• Analysis of the unavailabilities duration and its impact• Estimation of average times between unavailabilities
(by device or device and substation)• Estimation of average time between availabilities• Estimation of the impact rate for unavailabilities• Estimation of the next dates of failure risk in f (impact rate,
unavailabilities frequency)
