The Future of Predictive Technologies is Here Now Download/View

Experience has taught us that half the battle in ensuring electrical equipment reliability is to keep it Clean, Dry, Cool and Exercised. If these four items are accomplished, then currently available on-line predictive technologies can take care of the rest. With depleting technical expertise in electrical equipment and the pressures of running facilities 24 x 7 x 365, these new technologies offer the ability to fill the maintenance gap while reducing costs and increasing power system reliability. Due to the decreasing cost of these IED’s and the high cost of unplanned outages, a rapid ROI is achieved.

On-Line Trasformer Diagnostics Download/View

For decades, transformer asset managers have sought ways to assess the general condition of electrical power apparatus and identify specific problems. Periodic off-line diagnostic tests still play an important role in industry. However, “continuous� or “on-line� monitoring can overcome some of the fundamental limitations of off-line tests while increasing performance and reliability of the monitored equipment. As technology advances, additional continuous or on-line monitoring techniques are being developed and proven the in the field. This paper will present some newer on-line diagnostics methods and provide examples of monitoring and diagnostics for bushings and windings on transformers. These same techniques can be applied to high voltage current transformers, CCVTs and other equipment.
