Managing Data from Condition-Based Monitors
Challenges of Asset Data Management
It is important for organizations to understand what they intend to do with the data coming from online monitoring of transformers, circuit breakers and more. Data should be used for fleet management. Ideally, a plan would be outlined before implementing monitoring. However, the challenge faced is a daunting task of working collaboratively with various stake holders who have different priorities and requirements. There is also a bias to use existing operating systems to simplify architecture by leveraging previous communication and IT systems. Yet this often creates a conflicting environment where the existing systems and processes really do not meet the business requirements of condition-based monitoring. It is advantageous to benchmark with peer groups and listen to users who have mature systems in place.
How do I manage the data from condition-based monitoring?
When dealing with online monitoring, many have asked “what do I do with the data”? One of the biggest mistakes to avoid is sending too much information from the monitoring system to SCADA and relying on system operators to turn this information into an action plan. The reality is a system operator must prioritize immediate requirements to maintain system reliability and safety and will always deprioritize asset management information.
The solution is to partition information intended for asset management into a separate dashboard. There are several options to achieve this:
- Invest in PI database servers to address various business needs. Although extremely powerful, this approach can be expensive and resource intensive.
- Utilize a purpose-built end to end single vendor solution. This streamlines the process and reduces the resources and costs to manage a fleet of transformer and breaker monitors. This eliminates point to point SCADA mapping, provide concerns index for prioritization of work orders, and eliminates many of the organizational challenges to access data when sent to an operational control system such as SCADA.
How does a concerns index improve asset management?
Fundamentally, asset management is about resource allocation to optimize system reliability. Assets are continuously aging from the date of being put into service. Asset managers must provide recommendations on where maintenance and replacement budgets are best used to prevent unplanned outages and other service disruptions. No budget or resource pool is infinite, so assets must be prioritized based on some set of criteria. A concerns index is one tool utilized to simplify those decisions.
A concerns or health index can provide an overview status of the asset. The intent is to make it easy for asset managers to assess if equipment needs immediate attention or is in good operating condition. One of the key benefits of continuous online monitoring is the ability to trend the condition of equipment. This allows asset managers to make informed decisions if a known problem needs immediate attention or if it can be addressed during next planned outage. The concerns index provides some of this guidance by scoring assets that need immediate attention differently than those that are at low risk for failure. Therefore, the concerns index a key tool when performing risk management on a large fleet of power transformers and circuit breakers.
