Three Ways to Improve Your Outage Planning with EMI Testing
There are few things more frustrating for power customers and the industry than forced outages. While some outages are unplanned, many are essential for conducting condition-based tests on critical assets to ensure safe operations.
Luckily, there are ways to minimize planned outage time for testing and get back on-line sooner while simultaneously minimizing the number of forced outages. New in-service testing tools along with improved testing techniques give asset managers critical health information so they can understand what does and doesn’t need immediate attention ahead of failures. With this knowledge, managers can best allocate resources during planned outages and prioritize maintenance and repairs. Benefits of such an approach include:
- Cost savings by being more efficient with off-line inspections. Detailed information about asset condition in advance of an outage makes your inspection and repair work more accurate, efficient and effective.
- Time savings because you’ll already know where the problem lies (if you have a problem at all) before taking your system off-line. This means you can do in-depth testing of targeted areas to get to the root cause and solve issues quickly.
- Reduction of risk for in-service system failures is facilitated by routine testing to identify emerging and developing problems. By knowing the status of assets while they are in-service, you are able to proactively address potential problems before they lead to a forced outage.
A New Solution: EMI Surveyor
Our EMI Surveyor, a non-invasive surveying solution, offers a new way to conduct in-service testing that helps minimize outage times and get systems back on-line faster. Key product features include:
- It’s effective for all assets greater than 2300 volts. This includes generators, motors, bus duct systems, transformers, switchgear, cable terminations and other high voltage equipment.
- The technology is inherently safe. There’s no need for permanent connections or equipment design changes. As long as it is energized and has a path to ground that we can get a 120mm clamp-on radio frequency current transformer (RFCT) on, we can test it.
- Maintenance recommendations can be developed after the first test.
- The approach provides a broader view of more than 70 different electrical insulation and mechanical defects. This includes partial discharge, sparking, corona and arcing.
Knowing what equipment needs attention in priority order leads to successful outage planning and appropriately allocating maintenance assets. This results in reduced forced outages, shorter testing outages and improved business performance. These techniques help to ensure asset health is of the highest level while maximizing the performance of your maintenance budget.
