UV INSPECTION APPLICATIONS

The DayCor® family of cameras detects and captures both corona and arcing activity effectively. The awareness to corona discharge is shared among companies that have high voltage apparatuses and those that manufacture components for these apparatuses.

EPRI, IEEE, CIGRE and other institutions publish from time to time researches conducted with corona cameras. Sharing information on the use of available technologies is important because of the global aspects of the electrical markets. Based upon those leading knowledgeable organizations, there is a consensus in favor of using daytime corona cameras to achieve reliability and save losses.

Corona cameras are being used by the following:

Power companies and utilities focus on reliable ongoing power supply without outages. At the same time power companies and utilities strive to reduce maintenance costs and seek methods to predict the remaining life time of their assets.

Ofil's mission is to improve and develop diagnostic and monitoring methods and manufacture tools that will assist power companies to achieve these goals.

Information availability and feasibility

DayCor® provides immediate, on the fly, visible reliable, correct and relevant information:

  • Predictive — indicate specific symptoms prior to failure
  • Nonintrusive — no interruption of service is required nor any change of the regular operating voltage
  • Nondestructive — the tests do not affect/damage/change the equipment under inspection
  • No need for over loading the lines — testing is carried out during regular voltages
  • Trending-oriented — finding can be stored and retreivd for trending reports
  • Pinpointing — locating the partial discharge emmiting sources to facilitate repair
  • Cost effective — performing surveys at most facilities is fast and easy with meaningful important information
