condition monitoring systems

• Mitigate the risks of catastrophic failure.
• Help identify problem equipment.
• Address and manage the risks associated with the now-known
problematic equipment.
• Extend the life of existing assets.
• Situational awareness of how far you can “push” an asset.
• Provide remote visibility of operating parameters.
• Where feasible, eliminate routine, timed maintenance or reduce
its frequency saving time and money.
• Determine equipment condition and plan maintenance at
optimal times.
• Provide information to create an asset replacement plan.
• Gather and manage data reporting to asset visualization
software, a standard database or enterprise software platform.
Define the Goals – Why & What

3. Monitoring, Control and Communications for Electrical Power Apparatus
• Standardization is the route to the common ground required to
deploy, support and sustain a monitoring initiative over time,
across the company and with different OEM transformer
suppliers.
• While there are some differences that are necessary site-to-site
(example: cooling details or settings), extra effort making things
as standardized as possible across the fleet pays off in many
ways.
• Wherever possible, the system should use standard I/O
definition, the same type of sensors and commonality in as
many aspects as possible.
• DR will provide assistance based on many years of experience.
Define the Standards

• It is critically important to include your vision of the transformer
parameters needed in the spec regardless of which OEM
provides the transformer.
• Include and specify the relevant “hooks” in the transformer
specification so that the appropriate points you want to monitor
have the contacts, sensors points or access needed to
implement them. That does not happen automatically.
• Enforce the discipline across all transformer buys, regardless of
the OEM.
• Communicate the vision internally so that stake-holders and
colleagues can understand it and support it.
Incorporate the Vision

Manage the Data Content and Paths
• What path(s) will be used to deliver the information?
• What information subsets need to be directed to different stake-
holders and constituents (such as SME, maintenance,
operations).
• Who will be responsible for the data?
• Who will be assigned to respond and in what timeframe and
manner?
• Develop a Response Action Matrix so it is well-defined what to
do when and alarm is delivered.
• Who will have access and what access ruled will be used?

6. Monitoring, Control and Communications for Electrical Power Apparatus
• Training is critical and should include both written material and
hands-on interaction.
• Training give the crews the understanding and confidence to
use the system.
• Where possible, provide a readily-accessible summary of key
information that can provide a refresher when needed.
• Help develop “champions” in department sub-groups where
possible.
