Questions about future research plans

• New sensors and data acquisition equipment:

- Project #4 relates to this area - are there any needs for development of additional sensors through PSerc

• New way of collecting substation data coming from IEDs:

- Project #2 covers wireless comm. - are there other comm. technologies of interest for PSerc research

PSERC

Questions about future research plans• New way of processing data relevant to maintenance: - Project #3 covers condition-based maintenance and mobile agents - are there needs to explore other technologies/strategies and

how all of this relates to legacy solutions (RCM)

• Maintenance strategies: - Projects #1, 3, and 5 are talking about preventive, condition-based and just-in-time maintenance - How do the big picture and existing practice relate to what we are doing (or what needs to be done)

• Data Integration and Information exchange: - Projects #1,2 and 3 are addressing this issue - How this issue relates to maintenance and what additional needs

to be done
